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. (a) `-300 J`
B. (b) `-100 J`
C. (c) `+100 J`
D. (d) `+300 J`

Explanation

To solve the problem, we will use the first law of thermodynamics, which states:

\[ \Delta U = Q + W \]

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