A gas is compressed from a volume of 2 m^3 to a volume of 1 m^3 at a constant pressure of 100 N / m^2. Then it is heated at constant volume by…
A gas is compressed from a volume of $\displaystyle 2 \mathrm{~m}^3$ to a volume of $\displaystyle 1 \mathrm{~m}^3$ at a constant pressure of $\displaystyle 100 \mathrm{~N} / \mathrm{m}^2$. Then it is heated at constant volume by supplying $\displaystyle 150$ J of energy. As a result, the internal energy of the gas :
Official answer
(1)
Increases by $\displaystyle 250$ J
