16. Use PV = nRT. Convert pressure to atm (1 atm = 101.32 kPa) or use 8.314 for R.
17. I'll critique your answer. You know specific heat is high (almost higher than any other material) and you know density of ice is less than density of H2O at those temperatures.
18. Water boils at a lower temperature at elevated altitudes. It takes longer to cook something at 95 C than at 100 C.
#16 A gas occupies 7 L at 71.8 kPa & 30°C. Find its volume at 273K and 101.325 kPa. Show your work using the combined gas law.
#17 In the winter, bodies of water tend to not freeze solid. This allows fish and other aquatic life to survive below the floating ice. Explain the unique properties of water (high specific heat capacity and density) in the solid state as it relates to this situation.
#18 Explain why it takes longer to cook or bake certain foods at high altitudes compared to sea level.
