For the process $CO_2(s) \rightarrow CO_2(g)$,which of the following is true?

Which of the following processes is endothermic?

Identify the process that proceeds with no heat exchange between the system and the surrounding.

The relation between $\Delta E$ and $\Delta H$ is

For $1 \, \text{mole}$ of an ideal gas,isothermal expansion occurs from a volume of $2 \, L$ to $6 \, L$ at a temperature of $300 \, K$. The value of $\Delta U$ for this process is .............

In thermodynamics,the $P-V$ work done is given by $w = -\int P_{ext} dV$. For a system undergoing a particular process,the work done is $w = -\int \left(\frac{RT}{V - b} - \frac{a}{V^2}\right) dV$. This equation is applicable to a:
