How much heat energy is required to convert 77.4 g of liquid sulfur dioxide, SO, at 211.2 K to gaseous the molar heat of vaporization of So, is 24.9 kJ/mol, and the specific heat capacity (C) of liquid SO, is q = - TOOLS x10

The density of liquid oxygen at its boiling point is 1.14 kg/Lkg/L , and its heat of vaporization is 213 kJ/kgkJ/kg . How much energy in joules would be absorbed by 3.0 LL of liquid oxygen as it vaporized? Express your answer to two significant figures and include the appropriate units. ------ Water's heat of fusion is 80. cal/gcal/g , and its specific heat is 1.0calg⋅∘Ccalg⋅∘C . Some velomobile seats have been designed to hold ice packs inside their cushions. If you started a ride with ice packs that held 1300 gg of frozen water at 0 ∘C∘C , and the temperature of the water at the end of the ride was 32 ∘C∘C , how many calories of heat energy were absorbed? Express your answer to two significant figures and include the appropriate units. ---- Water's heat of fusion is 80. cal/gcal/g , its specific heat is 1.0calg⋅∘Ccalg⋅∘C, and its heat of vaporization is 540 cal/gcal/g . A canister is filled with 330 gg of ice and 100. gg of liquid water, both at 0 ∘C∘C . The canister is placed…
