URGENT PLEASE HELP!! 1. Why are the values for Molar Heats of Fusion always less than Molar Heat of Vaporization? In other words, why is the energy required to boil matter always greater than the energy required to
melt it?
2. Calculate the energy required to boil 2.5g of water assuming the Molar Heat of Vaporization for
water is 40.7 KJ/mole. SHOW WORK FOR CREDIT BOX OUT YOU ANSWER
3. How much energy is required to bring 35g of ice at -10°C to a liquid at 15°C ?
Cp ice = 2.06 J/g°C Cp liquid = 4.18 J/gºC
Molar Heat of Fusion = 6.02 KJ/mole

Problem page combustion of hydrocarbons such as pentane ( c5 h12 ) produces carbon dioxide, a "greenhouse gas." greenhouse gases in the earth's atmosphere can trap the sun's heat, raising the average temperature of the earth. for this reason there has been a great deal of international discussion about whether to regulate the production of carbon dioxide.(a) write a balanced chemical equation, including physical state symbols, for the combustion of liquid pentane into gaseous carbon dioxide and gaseous water. (b) suppose 0.350 kg of pentane are burned in air at a pressure of exactly 1 atm and a temperature of 20.0 degree c. calculate the volume of carbon dioxide gas that is produced.be sure your answer has the correct number of significant digits.
