Unformatted text preview: o C. To cool 1 liter of water from 10 o C to 0 o C you need to take out an amount of heat equal to Q=mc Δ T=1*4190*10 =41900 Joules. How much heat do you need to take out in order to transform the same water into ice at 0 o C. 1. 41900 Joules 2. More than 41900 Joules 3. Less than 41900 Joules What is sublimation? 1. Transformation from solid phase of matter to its liquid phase 2. Transformation from liquid phase of matter to its gaseous phase 3. Transformation from solid phase of matter to its gaseous phase by skipping the liquid (is it possible?) What are the mechanisms of the heat transfer? 1. Conduction 2. Conduction, Convection and Radiation 3. Conduction, Vaporization and Combustion...
