1. At 1 atm, how much energy is required to heat 91.0 g of
H2O(s) at –24.0 °C to H2O(g) at 171.0 °C?
2.When 1518 J of heat energy is added to 48.6 g of hexane,
C6H14, the temperature increases by 13.8 °C. Calculate the molar
heat capacity of C6H14.
3.A 56.90 g sample of a substance is initially at 21.3 °C. After
absorbing 1615 J of heat, the temperature of the substance is 146.8
°C. What is the specific...
