Question 1:How much energy (in kilojoules) is needed to heat 5.40g of ice from -12.5∘C to 28.5∘C? The heat of fusion of water is 6.01kJ/mol, and the molar heat capacity is 36.6 J/(K⋅mol) for ice and 75.3 J/(K⋅mol) for liquid water.
Question 2:How much energy (in kilojoules) is released when 7.55g of water at 31.0∘C is cooled to -13.0∘C? The heat of fusion of water is 6.01 kJ/mol, and the molar heat capacity is 36.6 J/(K⋅mol) for ice and 75.3 J/(K⋅mol) for liquid water.
Question 3:What is the vapor pressure of CS2 (in mm Hg) at 29.5∘C? Carbon disulfide, CS2, has Pvap = 100mm at -5.1∘C and ΔHvap = 28.0 kJ/mol.
Question 4:Assuming that the heat capacities don't change with temperature, how much energy in kilojoules is needed to heat 7.60g of Hg from a temperature of -58.0∘C to 51.0∘C?
