1) A piece of metal with a mass of 4.68g absorbs 256J of heat when its temperature increase by 182 C. What is the specific heat?
2) What is the specific heat of a substance that absorbs 2500 J of heat when a sample of 100.0 g of the substance increases in temperature from 10 C to 70 C.
3) If 200. grams of water is to be heated from 24.0 C to 100.0 C to make a cup of tea, how much heat must be added? The specific heat of water is 4.18 J/gC.
4) How many grams of water would require 2200 joules of heat to raise its temperature from 34°C to 100°C? The specific heat of water is 4.18 J/g∙C
5) A block of aluminum weighing 140 g is cooled from 98.4°C to 62.2°C with the release of
1080 joules of heat. From this data, calculate the specific heat of aluminum.
6) 100.0 g of 4.0°C water is heated until its temperature is 37°C. If the specific heat of water is 4.18 J/g°C, calculate the amount of heat energy needed to cause this rise in temperature.
7) How much heat, in joules, is needed to raise 20.0 grams of water from 5.00 C to 40.00 C?
8) How many grams of aluminum can be heated from 90.0 C to 120.0 C if 500 calories are applied? The specific heat of aluminum is 0.210 cal/gC.
