Question

В цилиндре с подвижным поршнем содержится газ при атмосферном давлении и температуре 27°С. При помощи поршня газ сжали до объема, вдвое меньшего, и одновременно нагрели до 327°С. Чему равно давление газа?

Answer 1

Дано
po=10^5  Па
To=27C = 300K
R =8.31
Vo/V =2
T = 327C = 600K
найти
p
решение
poVo = vRTo
pV = vRT
разделим  
pV  / poVo = vRT / vRTo
p = po* Vo/V * T/To
p = po *2 *600/300 = 4po = 4*10^5 Па

ответ 
4po = 4*10^5 Па

Answer 2

Calculation of the Gas Pressure

To calculate the final pressure of the gas after it has been compressed and heated, we can use the ideal gas law equation:

PV = nRT

Where: - P is the pressure of the gas - V is the volume of the gas - n is the number of moles of the gas - R is the ideal gas constant - T is the temperature of the gas in Kelvin

In this case, the initial conditions are: - Initial pressure (P1) = atmospheric pressure - Initial temperature (T1) = 27°C = 300K (converted to Kelvin)

The final conditions are: - Final volume (V2) = half the initial volume - Final temperature (T2) = 327°C = 600K (converted to Kelvin)

Since the number of moles (n) remains constant, we can rewrite the equation as:

P1V1/T1 = P2V2/T2

Substituting the given values: - P1 = atmospheric pressure - V1 = initial volume - T1 = initial temperature - V2 = final volume - T2 = final temperature

We can solve for P2, the final pressure of the gas.

Let's calculate it step by step.

1. Convert the initial temperature from Celsius to Kelvin: - T1 = 27°C + 273.15 = 300K

2. Convert the final temperature from Celsius to Kelvin: - T2 = 327°C + 273.15 = 600K

3. Since the final volume is half the initial volume, we can express it as: - V2 = (1/2) * V1

4. Substitute the values into the equation: - P1 * V1 / T1 = P2 * V2 / T2

5. Rearrange the equation to solve for P2: - P2 = (P1 * V1 * T2) / (V2 * T1)

Now, let's calculate the final pressure using the given values.

Given: - P1 = atmospheric pressure - T1 = 27°C = 300K - T2 = 327°C = 600K - V2 = (1/2) * V1

We need the value of the atmospheric pressure to proceed with the calculation. Unfortunately, the provided search snippets do not contain the necessary information to determine the atmospheric pressure. Therefore, we cannot provide an exact numerical answer to the question.

Please provide the atmospheric pressure, and we will be able to calculate the final pressure of the gas.
