A 60.80 gram sample of iron (with a heat capacity of 0.450 J/g◦C) is heated to 100.00 ◦ It is then transferred to a coffee cup calorimeter containing 52.42 g of water (specific heat of 4.184 J/ g◦C) initially at 20.47 ◦C. If the final temperature of the system is 28.78, what was the heat gained by the calorimeter? If the calorimeter had a mass of 25.19 g, what is the heat capacity of the calorimeter?

A 61.93 gram sample of iron (with a specific heat of 0.450 J/g °C) is heated to 100.0 °C. It is then transferred to a coffee cup calorimeter containing 40.6 g of water (specific heat of 4.184 J/ g °C) initally at 20.63 °C. If the final temperature of the system is 23.59, what was the heat absorbed (q) of the calorimeter? (total heat absorbed by the water and calorimeter = heat released by the iron)

A 48.79 g sample of metal is heated to 98.77oC and then quickly transferred to 88.34 mL of water at 24.65oC contained in a new calorimeter. This calorimeter has a calorimeter constant (heat capacity) with a numerical value of 55.7 (see problem 2e above for appropriate units). The thermal equilibrium temperature of the metal sample plus water mixture was 27.49oC. Assume the density of the water is 1.00 g/mL. a. How much heat in Joules is gained by the water?...
