- What does the first law of thermodynamics state? O All energy is converted to heat. Metabolic rate is constant. O Energy can neither be created nor destroyed. O Food increases metabolic rate.If an ideal gas is compressed isothermally: The internal energy of the gas decreases. No work is done in the process O Heat is transfered from the gas Work is done by the gas.
