But it does not mean that the formula that 0.001aв1i is equal to 1l will hold.

And the correct formula should be:

xaвci.

td

x and cd are unknown numbers

It's to stir, to mix.

t is time, which is known to be 168 seconds.

Represents unknown.

Moreover, the process of this formula is tortuous and long. Zhou Wenwen thinks that his junior high level will definitely not be able to supplement this formula. When he meets Iron Man later, he can talk to him.

But as the saying goes, true knowledge comes from practice. Zhou Wenwen can first try out how powerful 1L unit of ash energy is.

Thinking of this, Zhou Wenwen's interest suddenly increased. He pressed the button of the armor on his left hand, took over the aβ electron absorption cycle conversion and emission ash energy 0.1 system, called out 3 degrees of aβ energy and 10a current, and quickly introduced it into the accelerator tube to circulate.

The time setting is to launch after 1 second.

So more than 2 minutes later, that is, 168 seconds and 1 second later, a white energy beam shot out from the mouth of the electronic cycle device and hit the rear armor plate of the pickup truck 33.02 meters away from Zhou Wenwen within 55.1 seconds.

The armor piece on the rear of the pickup truck immediately left the rear of the pickup truck and flew more than 66.72 meters within 57.21 seconds before landing. According to the hunter's mapping, it was meters.

After getting the value, Zhou Wenwen started to calculate. First, according to the first value formula of formula td, he will get:

1x3aв10ad这个第二值公式，鉴于0.001度aв1a等于1l，导入第二值公式解出可得:

1x31x102.997aв30l2.997aв。

Represents remainder, package.

It is known that the unit of qirt is j, which is joule, which is the unit of energy and work. One joule of energy is equal to the work done by the point of application of 1 Newton force moving a distance of 1 meter in the direction of the force.

Then substitute 30l2.997aв into the formula ir, and you will get the third value formula q30l2.997aвxt.

Since the rear armor piece of the pickup truck flew 57.21 meters, the third value formula can be introduced to solve:

57.21jq30l2.997 degrees aвxt is the fourth value formula.

It is also known that the time for the rear armor piece of the pickup truck to fly out is 6.72. By importing the fourth value formula and solving it, we can get:

57.21j30l2.997degreeaвx6.72s

Simplified, we get:

8.51339286j4.46428571l0.445982143 degrees aвx1s is the fifth value formula.

So what is the use of this fifth value formula and is it correct?

Zhou Wenwen didn't know the answer, but he knew that this fifth value formula could be used as a comparison.

Zhou Wenwen took a deep breath and pressed the button of the left armor again, taking over the aβ electron absorption cycle conversion and emission ash energy 0.1 system, calling out the 15 degrees aβ energy and 18a current, and introducing it into the accelerator tube to circulate.

If the time is still set, it will be launched after 1 second.

Just like that, 168 seconds and 1 second later, a light beam of white energy that was not thick came out from the nozzle of the electronic cycle device with a whooshing sound, and hit the front of the pickup truck straight. And next time, something unexpected happened. .

The front of the pickup truck did not fly out like the rear armor piece of the pickup truck. Instead, it melted into a small hole and exploded immediately. Apparently, the energy beam penetrated the fuel pipe of the pickup truck front and generated high temperature, which ignited the gasoline. Finally, Produce an explosion.

So how to calculate this second example?

Zhou Wenwen couldn't help but fell into deep thought.

Zhou Wenwen knew that under normal atmospheric pressure, the auto-ignition point of gasoline is 427c.

However, gasoline evaporates quickly, and gasoline vapor is easily ignited when mixed with air, which will also cause the flash point of gasoline to be lower than about 28°. Generally, the lower the flash point, the higher the auto-ignition point.

The flash point is the temperature at which oil can flash ignite when exposed to an open flame when heated to a certain temperature. The autoignition point is the temperature at which oil reaches a certain temperature and comes into contact with enough oxygen in the air to cause combustion.

To be on the safe side, Zhou Wenwen initially estimated that after the energy beam penetrated the oil pipe, when the gasoline merged with the air, the energy beam with a surface temperature of 20 degrees extinguished the gasoline, eventually causing an explosion.

Leaving aside gasoline, the key now is the energy beam with a surface temperature of 20 degrees.

And this involves specific heat capacity.

Specific heat capacity, the English abbreviation is shc, the English full name is specific heat capacity, symbol c.

shc, short for specific heat, also known as specific heat capacity, is a physical quantity commonly used in thermodynamics to express the ability of a substance to absorb or dissipate heat. The greater the specific heat capacity, the greater the material's ability to absorb or dissipate heat.

That is, the heat absorbed or released by a unit mass of a substance that increases or decreases by a unit temperature.

Its unit in the International System of Units is joules per kilogram Kelvin j kgk or joules per kilogram per degree Celsius j kgc, where j refers to joules and k refers to the thermodynamic temperature scale, that is, the time required to increase or decrease the temperature of 1 kilogram of substance by 1 kelvin. energy.

According to this theorem, the most basic formula can be derived:

cqmΔt

q is the heat absorbed or released, m is the mass of the object, and Δt is the change in temperature after absorbing or releasing heat.

In junior high school textbooks, Δt is written as Δt. In fact, this is irregular. In our daily life, c is often used as the unit of temperature, and k is rarely used, and ΔtΔt. Therefore, Δt is used in middle schools, but in international or higher scientific fields Still use Δt.

It is known that the temperature is 20 degrees, the specific heat capacity of pickup truck gasoline is about 0.8 to 1.8, and the minimum estimate of pickup truck gasoline pipe is 1 liter and the maximum is 6 liters. Four formulas can be obtained by importing the formula:

0.8201Δt

0.8206Δt

1.6201Δt

1.6206Δt

Δt variant solution:

Δt25, Δt4.17.

Δt12.5, Δt2.08.

It can be seen that after the energy beam hits any object, it can generate a temperature of at least 1 degrees and a maximum of 3 degrees within 2 to 25 seconds.

In the first value formula of td, there is also a corresponding explanation, that is, the temperature rise, that is

15aв18i.

3 heating d.

But Zhou Wenwen was not satisfied with this, so he decided to try again.

He pressed the button of the left armor again and took over the aβ electron absorption cycle conversion emission ash energy 0.1 system, and this time he adjusted the remaining 92 degrees aβ energy and 73a current, and introduced it into the accelerating tube to circulate.

The time is still set to launch after 1 second, and this time the target is a piece of iron with an area of ​​1 square meter and a weight of about 15 kilograms.

So more than 2 minutes later, that is, 168 seconds and 1 second later, another white energy beam shot out from the nozzle of the electronic cycle device, hitting the iron piece 66.12 meters away from Zhou Wenwen within 3029.1 seconds.

As if being thrown with great force, the iron piece flew more than 3 meters in one fell swoop and went deep into the ground. The whole process took less than 275.124 seconds. According to hunter mapping, the iron piece flew 2.712 meters and the flight time was seconds.

After getting the value, Zhou Wenwen started to calculate again. First, according to the first value formula of heating d according to the formula t, he will get:
