If a gas absorbs `200J` of heat and expands by `500 cm^(3)` against a constant pressure of `2 xx 10^(5) N m^(-2)`, then the change in internal energy is

Options

A. `-300 J`
B. `-100 J`
C. `+100 J`
D. `+300 J`

Explanation

To find the change in internal energy (ΔU) of the gas, we can use the first law of thermodynamics, which states:

\[ \Delta U = Q - W \]

Where:
- \( \Delta U \) = change in internal energy
