- Calculate the value of KW when the temperature is 30.0 °C. Multiply your answer by 1014 before entering it. (R = 8.3145 J mol-1 K-1)The energy released from fission is about 200 MeV per fission event or 3.2-10-11 J per 235U nucleus. The fission of 1 g of 235U generates about 1 MW of thermal power; thus, a reactor that contains 1 kg of 235U fuel generates about 1 GW (109 W). If the reactor core is immersed in a heat bath containing 8.7.105 liters of water (12 m x 6 m x 12 m) initially at 25°C, how long will it take for the water to begin to boil off? Assume that the heat capacity of water is constant and that there is no heat lost from the reactor coolant to the surroundings.A sample of helium is initially at 605 torr in a volume of 2.85 L. At 24.7 °C you found the density of He to be 0.130 g/L and the density of Ar to be 1.30 g/L even though both samples had the same number of moles. Which one of the following best explains why the densities are different? A B C D Argon is a heavier atom than helium, so it has more mass in the same volume occupied by the gas. Argon is a larger atom than helium so it occupies more volume. An argon atom is more dense than a helium atom. The densities are different only because of rounding.
