(58) the pressure of a gas in a tank is 422 psi at
20.0k. what is the pressure at 60.0k?
a. 1270 psi
7.480 atm
c. 1270 atm
d. 480 psi

1270 Psi

Explanation:

We are given;

Pressure in the tank, P₁ as 422 psiTemperature in the tank, T₁ as 20.0 K New temperature in the tank, T₂ as 60.0 K

We are required to determine the pressure at 60.0 K

We are going to use the pressure law;According to the pressure law, the pressure of a gas is directly proportional to  the temperature at constant volume.That is; Thus, At different pressures and temperature;

Thus, rearranging the formula;

Hence;

Therefore;

P₂=1266 Psi

   = 1270 Psi

Thus, the pressure at 60.0 K is 1270 Psi

What are the choices?
