5) You wish to heat water to make coffee. How much heat (in joules) must be used to raise the temperature of 0.180 kg of tap water (enough for one cup of coffee) from 19 °C to 96 °C? 6) When steam condenses to liquid water, 2.26 kJ of heat is released per gram. The heat from 168 g of steam is used to heat a room containing 6.44 x 104 g of air. The specific heat of air at normal pressure is 1.015 J/gºC. What is the change in air temperature, assuming the heat from the steam is all absorbed by the air? 7) Colorless nitric oxide, NO, combines with oxygen to form nitrogen dioxide, NO., a brown gas. 2 NO (g) + O₂(g) - 2 NO₂ (g) ΔΗ = -114 kJ What is the enthalpy change per gram of nitric oxide?
