At constant volume, 3 moles of an ideal gas when heated from 300k to 500k changes its internal energy by 5000 J. the molar heat capacity at constant volume is ………J/K/mole?

A certain volume of a gas at 300K is heated such that its volume is 3X the original amount and its pressure is 4.25X the original amount. Find the new temp

The molar specific heat at constant volume of an ideal gas is equal to 2.5 times the universal gas constant (8.314 J/mol.K). When the temperature increases by 100k, the change in molar specific enthalpy is ___ J/mol.:

An ideal gas receives 425 J of heat and expands by 1.50 L against an external pressure of 100.0 kPa.  What is the change in internal energy of the system? Use-full formula...!ΔW = p ΔV
