How long would it take (in seconds) to heat 188.9ml of water from 20∘C to 85.0∘C using a heater with a power rating of 50 W (i.e., it puts out 50 Joules of energy every second)? (For water: use 334 kJ/kg for the latent heat of fusion, 2.26×103 kJ/kg for the latent heat of vaporization, and 4.19 kJ/kg∘C for the specific heat. Also for water: remember that 1 ml has a mass of approximately 1 g) Note about format if using scientific notation. This system is very particular about entering numbers in scientific notation example 3.1∗10∧−24 in the answer box exactly in this format with no spaces. For this question you also can ONLY use one place after the decimal, as in the formatting example above. Type your answer... 1 point Which of the following curves describes what happens to the temperature of a water-ice mixture originally at 0∘C when heat energy is transferred to it at a constant rate, at standard (1atm) pressure (at sea level).
