It takes 2.0 x 106 J of heat to bring a quantity of water from to a boil. What is the mass of water?
Answer to relevant QuestionsThe lowest natural temperature ever recorded on the Earth was at Vostok, a Russian Antarctic station, when a temperature of – 89.4 oC (–89.4oC) was recorded on July 21, 1983. Atypical person has a body temperature of, ...A 0.60 kg piece of ice at 14oF is placed in 0.30 kg of water at 323 K. How much liquid is left when the system reaches thermal equilibrium? A 200-kg cast iron machine part at 500oC is left to cool at room temperature. Assume the machine part is a cube and has an emissivity of 0.780. At what rate is the machine part initially losing heat due to radiation? If heat engine A absorbs more heat than heat engine B from a hot reservoir, will engine A necessarily do more net work than engine B? Explain your reasoning. Suppose that after the final process in Fig. 12.22 (Exercise 10), the pressure of the gas is decreased isometrically from 1.0 x 105 Pa to 0.70 x 105Pa, and then the gas is compressed isobarically from 1.0 m3 to 0.80 m3.
