1.) DHvap is a way to measure intermolecular forces quantitatively. Calculate the amount of energy (in kilojoules) needed to cool 646 g of water vapor from 150°C to -17 °C. Assume that the specific heat of water is 4.184 J/g °C over the entire liquid range and the specific heat of steam is 1.99 J/g °C. The DHvap for water is 40.79 kJ/mol. The DHfus = 6.01 kJ/mol. 2. Diethyl ether is a volatile, highly flammable organic liquid that is used mainly as a solvent. The vapor pressure of diethyl ether is 401 mmHg at 18 degrees C. Calculate its vapor pressure at 52 degrees C.
