Question

Which one of the following is the correct expression for change in the internal energy for a small

temperature change $\triangle$  for an ideal gas?

(a) $\triangle U=C_{v}\times \triangle T$

(b) $\triangle U=C_{p}\times \triangle T$

(c) $\triangle U=\frac{C_{p}}{C_{V}}\times \triangle T$

(d) $\triangle U=\left ( C_{p}-C_{V} \right )\triangle T$

Answer 1

based on constant volume process internal energy
