How long would it take to heat 192ml of water from 20 0C to 76 0C using a heater with a power rating of 50W (i.e., it puts out 50Joules of energy every second)?
(For water: use 334kJ/kg for the latent heat of fusion, 2.26X103kJ/kg for the latent heat of vaporization, and 4.19kJ/kgoC for the specific heat. Also for water: remember that 1 ml has a mass of approximately 1g)

QUESTION 8 How does the internal energy of the ice and water mixture change if the temperature does not rise while the ice is melting? It decreases, because you need to use energy to make a freezer run, but ice melts spontaneously. No enough information to determine. It increases, because it takes more energy for water molecules to be disordered than to be ordered. It remains the same, because both are at the same temperature. QUESTION 9 Suppose you start...
