A group of students place a 0.045 kg water sample, initial temperature 21.5 degrees Celsius, on a heat source. The water is then warmed up to its boiling point then further heated until it is completely evaporated. Note: Both the heat source and the water are in a thermally isolated container. i. Find the total heat absorbed by the water during this process. ii. A similar experiment is performed on an unknown liquid, mass=0.055kg with initial temperature 21.5 degrees Celsius....

155 grams of ice at -10.0 degrees celsius is added to 1.17 kg of water at 70.0 degrees celsius and mixed together in thermal isolation until they come to equilibrium. The specific heat of ice is 2010 J/kgC. The specific heat of water is 4186 J/kgC. The latent heat of fusion for water is 3.34x10^5 J/kg. The latent of vaporization for water is 2.26x10^6 J/kg. What is the final equilibrium. The answer is 51.9 celsius. I just need the steps...

Problem 13: Suppose you place 0.255 kg of 20.5°C water in a 0.45 kg aluminum pan with a temperature of 144.5°C, and 0.012 kg of the water evaporates immediately, leaving the remainder to come to a common temperature with the pan. What would be the final temperature, in degrees Celsius, of the pan and water? The heat of vaporization of water is Lv = 2256 kJ/kg. You may neglect the effects of the surroundings and the heat required to raise...

Temperature Change and Phase Change - Specific Heat and Latent Heat - From COLD ICE to Warm Water The quantitative relationship between heat transfer and temperature change is Q = mcAT, where Q is heat transfer, m is the mass of the substance, and AT is the change in temperature. The symbol c stands for specific heat which depends on the material and phase (for exmample, water and ice have different specific heat). The specific heat...
