Question

An ideal gas is compressed in a closed container its U?

• A. Increases
• B. Decreases
• C. Remains same
• D. Both $\left(1\right)$ & $\left(2\right)$

Answer 1

The correct option is A Increases

When an ideal gas is compressed in a closed container, its internal energy U increases. Compressing an ideal gas increases its temperature and its internal energy increases since U = f(t) for an ideal gas.
