At the Olympic games, a 73.2 kg diver performs an inward straight dive in which she stands on the 10.0 m platform with her back to the water, then rotates the forward direction and plunges 10.0 m downward into the 28.0°C pool, briefly coming to a stop. (a) What is the entropy change of the system of the diver and the swimming pool for the time interval beginning when the diver leaves the platform and ending when the diver has come to a stop? (Give your answer in J/K.) J/K (b) The diver remains in the pool after her dive to watch the remainder of the Olympic event, and her core temperature slowly drops from 37.0°C to 36.0° Assuming that the temperature of the swimming pool remains unchanged at 28.0°C and that the diver does no work and does not metabolize any food during this interval, what is the change in entropy of the system of the diver and the swimming pool after her core temperature has reached 36.0°C? (C your answer in J/K. Assume the specific heat of the diver is equal to the specific heat of water, 4,186 J/(kg . °C).) J/K Nood Help? Road It

Consider a 50.0 g ice cube placed in a container containing 200 g of water. The water is initially at 25.0*C and the ice cube comes directly from a freezer at -15.0*C. Assume no heat is lost to the surroundings and negligible heat loss from the container. Determine the total change in entropy as a result of the mixing process.

What is the decrease in entropy (in J/K) of 27.5 g of water that condenses on a bathroom mirror at a temperature of 32.0°C, assuming no change in temperature and given the latent heat of vaporization to be 2450 kJ/kg? J/K
