One mole of an ideal gas at 25^(@)C expands in volume from 1.0 L to 4.0 L at constant temperature. What work (in J) is done if the gas expands against vacuum (P_("external") = 0) ?
10 mole of ideal gas expand isothermally and reversibly from a pressure of 05atm to 1atm at 300K . What is the largest mass which can lifted through a height of 1 meter? (g= 9.8 ms^(-2)
If one mole of an ideal gas (C_(p.m.)=(5)/(2)R) is expanded isothermally at 300K until it’s volume is tripled, then change in entropy of gas is:
A sample of an ideal gas is expanded 1 m^(3) to 3 m^(3) in a reversible process for which P=KV^(2) , with K=6 "bar"//m^(6). What is work done by the gas (in kJ) ?
An ideal gas undergoes isobaric expansion at pressure P from volume V_1 to V_2 the work done is :
