Prоf. Hаmiltоn puts а pоt contаining 1L of room temperature water onto his electric stovetop, which introduces a constant amount of heat each second to the water. In the first 2 minutes, the pot's temperature increases from 20°C to 60°C. Afterward, the pot was left unattended for another 8 minutes. (The professor was distracted reading the wiki for the obscure fighting game Under Night In-Birth II). During this time, heat is transferred to the pot at the same rate as before. At the time the professor returns to the stovetop, the pot had been heated for a total of 2 + 8 = 10 minutes. What is the temperature of the water at this time? (You can assume atmospheric pressure 101.325 kPa. The specific heat of water is 4.186 kJ/(kg * °C). The heat of vaporization of water is 2256 kJ/kg)
