Question

An ideal gas is enclosed in a cylinder that has a movable piston on top. The piston has a mass m and an area A and is free to slide up and down, keeping the pressure of the gas constant. How much work is done on the gas as the temperature of n mol of the gas is raised from T1 to T2? (Use any variable or symbol stated above along with the following as necessary: R.)

Answer 1

Answer:

Explanation:

Given mass of piston $\left ( m\right )$

no. of moles =n

Given Pressure remains same

Temperature changes from $T_1 to T_2$

Work done$\left ( W\right ) is given by=\int_{V_1}^{V_2}PdV$

W=$P\left ( V_2-V_1\right )$

also $PV_1=nRT_1$

$PV_2=nRT_2$

$W=nR\left ( T_2-T_1\right )$
