1. A metal weighing 30 g absorbs 200.0 J of heat when its temperature increases by 80.0°C. What is the specific heat capacity of the metal?
2. Calculate the mass (in grams) of iron that could be warmed from 20°C to 65°C by applying 4.5 kJ of energy. The specific heat capacity of iron is 0.45 J/g•°C.
3. How much heat in kilojoules is released when 500.0 g of water is cooled from 85.0ºC to 10.0ºC?
4. The specific heat capacity of water is 4.184 J/(g•°C).4. If 2200 J of heat is absorbed by a sample of iron weighing 50.0 grams, how many degrees would its temperature change? The specific heat capacity of iron is 0.45 J/g•°C.5. The specific heat capacity of diamond is 0.509 J/g•°C, and 5000 J of energy is required to heat a 50 g sample of diamond to a final temperature of 98°C. What was the sample's initial temperature?
