How much heat energy is required to raise the temperature of 0.368 kg of copper from 23.0 ∘c to 60.0 ∘c? the specific heat of copper is 0.0920 cal/(g⋅∘c) .

Does the temperature affect the solubility of sugar and salt in water? if it does tell me like different temperatures with different solubilities so i can sketch down a graph

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.
