A 235-g sample of a substance is heated to 330 °C and then plunged into a 105-g aluminum
calorimeter cup containing 195 g of water and a
17-g glass thermometer at 12.5°C. The final
temperature is 35.0°C. The value of specific heat
for aluminium is 900 J/kg. C for glass is
840 J/kg. Cand for water is 4186 J/kg.
Part A
What is the specific heat of the substance? (Assume no water boils away)
