Acoffee cup calorimeter contains 160.73 g of water at 24.28 °c. a 66.657 g piece of iron is heated to 98.83 °c. the piece of iron is added to the coffee cup caloriemter and the contents reach thermal equilibrium at 27.24 °c. the specific heat capacity of iron is 0.449 and the specific heat capacity of water is 4.184 g. k how much heat, q, is lost by the piece of iron? qiron = how much heat, q, is gained by the water? gwater = gwater = the difference between the heat lost by the piece of iron and the heat gained by the water is due to heat transfer to the styrofoam and the heat required to raise the temperature of the calorimeter. what is the heat capacity of the styrofoam calorimeter in joules per kelvin () ? ccalorimeter what would be the final temperature of the system if all of the heat lost by the iron was absorbed by the water? tfinal =

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.
