Which relation is correct for an isochoric process?

An ideal gas goes from an initial state to a final state. During the process,the pressure of the gas increases linearly with temperature. Which of the following statements are correct?
$A.$ The work done by the gas during the process is zero.
$B.$ The heat added to the gas is different from the change in its internal energy.
$C.$ The volume of the gas is increased.
$D.$ The internal energy of the gas is increased.
$E.$ The process is isochoric (constant volume process).
Choose the correct answer from the options given below $:-$

The thermodynamic process in which the work done on or by the gas is zero is:

$A$ sample of ideal gas $(\gamma = 1.4)$ is heated at constant pressure. If $100 \ J$ of heat is supplied to the gas,the work done by the gas is ...... $J$.

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

$A$ gas expands by $0.25 \, m^3$ at a constant pressure of $10^3 \, N/m^2$. The work done is:
