In an experiment 28.5g of metal was heated to 98.0c and then quickly transferred to 150.0g of water in a calorimeter. the initial temperature of the water was 20.5c amd the final temperature after the addition of the metal was 32.5c assume the calorimeter behaves ideally and does not absorb or release heat.

Harvey kept a balloon with a volume of 348 milliliters at 25.0˚c inside a freezer for a night.  when he took it out, its new volume was 322 milliliters, but its pressure was the same.  if the final temperature of the balloon is the same as the freezer’s, what is the temperature of the freezer? the temperature of the freezer is  kelvins.
