- The number of kilocalories in food is determined by calorimetry techniques in which the food is burned and the amount of heat transfer is measured. How many kilocalories per gram are there in a 5.00-g peanut if the energy from burning it is transferred to 0.500 kg of water held in a 0.100-kg aluminum cup, causing a 54.9°C temperature increase?If the price electrical energy is $0.08 per kilowatt hour, what is the cost of using electrical energy to heat the water in a swimming pool (12.0 m x 9.00 m x 1.50 m) from 16 to 28 °C? Number Units the tolerance is +/-2%How much heat energy must be removed from 0.10 kg of oxygen with a temperature of 22 °C in order for the oxygen to liquefy at -183 °C? (Co = 913 J/kg°C, Ly = 2.13 x 105 J/kg and oxygen liquefies as -183 °C) O 5 x 10^4 J O 9 x 10^4 J O 1 x 10^4 J O 4 x 10^4J
