Internal energy and thermodynamics
A question about the first law of thermodynamics states:
∂U = ∂Q + ∂W (U= internal enegy, Q=thermal energy supplied to system, W=work done on system)
An ideal gas is compressed at constant temperature, what is the effect on U, q and W?
The answer is that U remains constant, q decreases and W increases.
What I want to know is if a gas is compressed why does q decrease?
