17.1 kg water in the pond turns to ice in that he 2. a). How much energy is given to your body when 0.4 kg of steam condenses on your skin? b). If the same amount of energy were used to warm 4 kg of water( which is ten times the amount of steam) initially at 0 deg Celsius, what would be the final temperature of the water in deg C and c) in deg F? * 3. The heat of vaporization of ethyl alcohol is 8.5 x 10^5 J/kg. If 2 kg of it od 07 were allowed to vaporize in a refrigerator, how much energy would be drawn from the air molecules? *

A graph of temperature versus time for a substance that has a mass of 2.00 kg is shown below. The sample is at a temperature of-10.0 degrees celsius and initially in the solid phase. Heat is added to the sample at a constant rate of 20.0 kj/minute. B& Care at a temperature of 119 degree Celsius. Answer the following questions: 1. What is the melting point of this substance? 2. What islare the phase/phases that exists/exist during the process from A to B and during the process from B to C? 3. Use the graph to calculate the specific heat for this substance in solid phase. 4.Use the graph to calculate the latent heat of fusion for this substance.
