Q. When $1$ mole gas is heated at constant volume, temperature is raised from $298K$ to $308K$. Heat supplied to the gas is $500J$. Then which statement is correct?

Q. When 1 mole of a gas is heated at constant 1 volume, temperature is raised from 298 K to 308 K. Heat supplied to the gas is 500 J. Then, which statement is correct?

Q. One mole of an ideal gas requires 207 J heat to raise the temperature by 10K when heated at constant pressure. If the same gas is heated at constant volume to raise the temperature by the same 10K, the heat required is (R$=$8.3 J/mol-K)
