An ideal gas is compressed in a closed container its U?
- A. Increases
- B. Decreases
- C. Remains same
- D. Both (1) \& (2)
Step-by-step solution
For an ideal gas, internal energy depends only on temperature. During compression, work is done on the gas, which can increase temperature (if adiabatic) or cause heat loss (if isothermal or cooled), leading to temperature decrease. Since the process is not specified, internal energy can either increase or decrease, but not remain the same under typical interpretations of compression.
