Methane, CH_4, is a gas at room temperature but dichloromethane, CH_2CI_2 is a liquid. Why? Water will rise up into a capillary tube. Why and how is this phenomenon important in nature? Calculate the amount of heat in KJ that is required to heat 20.0 g of ice from -25 degree C to 90 degree C, and sketch a heating curve for the process. The specific heat of ice is 2.11 3/(g degree C); water 4.18 J/(g degree C) and the Delta H for water is 6.01 kJ/mol Calculate the amount of heat liberated when a 10.0 g of steam is converted to water 75.0 degree C and sketch a cooling curve for the process. The specific heat of steam is J/(g degree C); water are 4.18 J/(g degree C) and the Delta H for water is 40.6 kJ/mol.
