If a sample of gas has a volume of 5.00 L @ 92.3 C, what will the volume of the gas be if the temperature is lowered to - 37 C

On melting of ice, there is a decrease in volume instead of increase. Why?

When a dolphin jumps, it moves its muscles and chemical potential energy is converted to kinetic energy. Some of this energy is lost to the dolphin. Explain why this phenomenon does not violate the Law of Conservation of Energy.
