The condition $dQ = dU$ (heat supplied equals the increase in internal energy) is true for which of the following processes?

In an isobaric process,the work done by a diatomic gas is $10 \ J$. The heat given to the gas will be (in $J$):

At constant pressure,what fraction of the heat supplied to an ideal gas is converted into mechanical work?

$n$ moles of an ideal gas with constant volume heat capacity $C_v$ undergo an isobaric expansion by a certain volume. The ratio of the work done in the process to the heat supplied is

$A$ gas expands under constant pressure $P$ from volume $V_1$ to $V_2$. The work done by the gas is

When $1 \, mol$ of nitrogen gas is heated at constant pressure at room temperature,it is supplied with $1163.4 \, J$ of energy. The increase in temperature is ....... $K$ $(R = 8.31 \, J \, mol^{-1} \, K^{-1})$.
