Calculate the enthalpy change delta H for the vaporization of 100.0 g of water at100.0°C.
2. Ethylene glycol is used in automobile coolant systems because its aqueous solutions lower the freezing point of the coolant liquid and prevent freezing of the system during Canadian winters. What is the enthalpy change needed to completely vaporize 500.0 g of ethylene glycol?
3. Under certain atmospheric conditions, the temperature of the surrounding air rises as a snowfall begins, because energy is released to the atmosphere as water changes to snow. What is the enthalpy change delta H for the freezing of 1.00 t of water at 0.0°C to 1.00 t of snow at 0.0°C? (Recall that 1 t 1000 kg.)
