A 9.1 g piece of aluminum (specific heat= 0.22 cal/(g* Celsius) received 10.0 cal of heat. What was the change in temperature?

A piece of iron was heated to 95.4C and dropped into a constant-pressure calorimeter containing 284 g of water at 32.2C. The final temperature of the water and iron was 51.9C. Assuming that the calorimeter itself absorbs a negligible amount of heat, what was the mass (in grams) of the piece of iron? The specific heat of iron is 0.449 J/(gC), and the specific heat of water is 4.18 J/(gC).

Methane, CH4, is a major component of marsh gas. When 0.5000 mol methane burns to produce carbon dioxide and liquid water, 445.1 kJ of heat is released. What is this heat in kilocalories?

As a child plays on a swing, at what point in her movement is her kinetic energy the greatest? At what point is potential energy at its maximum?

Homes may be heated by pumping hot water through radiators. What mass of water will provide the same amount of heat when cooled from 95.0 to 35.0 C, as the heat provided when 100 g of steam is cooled from 110 C to 100 C.

A block of aluminum and a block of iron, both having the same mass, are removed from a freezer and placed outside on a warm day. When the same quantity of heat has flowed into each block, which block will be warmer? Assume that neither block has yet reached the outside temperature. (See Table 6.1 for the specific heats of the metals.)

Which of the following has the highest thermal energy? (a) 1.0 g of ice at 0 (b) 1.0 g of liquid water at 25 C (c) 1.0 g of liquid water at 100 C (d) 1.0 g of water vapor at 100 C

Copper is used in building the integrated circuits, chips, and printed circuit boards for computers. When 228 J of heat are absorbed by 125 g of copper at 22.38C, the temperature rises to 27.12C. What is the specific heat of copper?

How much heat, in joules and in calories, must be added to a 75.0g iron block with a specific heat of 0.449 Jig C to increase its temperature from 25 C to its melting temperature of 1535 C?
