1) What is the specific heat of a substance that absorbs 2.5 x 103
joules of heat when a sample
of 1.0 x 104 g of the substance increases in
temperature from 10.0C to 70.0C?
2) A 1.0 kg sample of metal with a specific heat of 0.50 KJ/KgC is heated to
100.0C and then
placed in a 50.0 g sample of water at 20.0C. What is the final
temperature of the metal and
the water?
3) A 2.8 kg sample of a metal with a specific heat of 0.43KJ/KgC is heated to
100.0C then
placed in a 50.0 g sample of water at 30.0C. What is the final
temperature of the metal and
the water?
