Q=mcΔT, solve for unknown
1) Determine how many joules of energy are
released when 870. g of aluminum is cooled from
155 °C to 20.0 °C. (Ans. 1.07 x 10^5 J released)
2) 6.00 x 102 kg of pyrex glass loses 8.70 x 106 J of thermal
energy. If the temperature of the glass was initially 95.0 °C
before cooling, calculate its final temperature.
(Ans. 349 K)
3) 5.4 x 106 J of energy is required to heat a 28 kg
mass of steel from 22 °C to 450 °C. Determnine the
specific heat capcacity of the steel. (Ans. 450 J/kg K)
4) How much thermal energy is needed to raise the
temperature of 2.50 g of water from its freezing point to
its boiling point? (Ans. 1050 J)
5) 1.7 MJ of energy is removed from a 15 kg mass of brass as it cools from 400 °C to 25 °C. Determine the specific
heat capacity of brass. (Ans. 3.02 x 102 J/kg K)
