Check my answers i really need ! heat and temperature are the same thing, but possess different units. true false molecular motion is independent of temperature and is unaffected by a change in temperature. true which describes how a microwave transfers heat to leftover mashed potatoes? radiation excites the motions of water molecules in the food, raising their total kinetic the hot oven comes in contact with the cold food and heat is transferred until both are at the same temperature heated air currents circulate around the food, transferring their kinetic energy to the food particles spinning the food on a turntable transfers kinetic energy to the food particles if the change in enthalpy is negative, δh is negative, and heat is absorbed during the change. false when concentrated sulfuric acid is added to water in a beaker, the beaker gets very warm. the temperature change indicates an exothermic process has occurred. true which of the following describes an endothermic reaction? thermal energy is released by the system. thermal energy is absorbed by the thermal energy is absorbed by the system. thermal energy is not transferred. the unit for specific heat is j/°c. true the specific heat of a substance is 2.23 j/g·°c. if given 11.2 grams of the substance and 368 joules of heat is released, what is the change in temperature of the substance? 14.7 degrees c 73.2 degrees 6.79 x 10−2 degrees c 9190 degrees c the specific heat of a substance is 2.91 j/g·°c. if given 10.4 grams of the substance and if the temperature of the substance increases by 26 degrees celsius, how much heat is absorbed? 790 7.9 x 102 kj 7.9 x 10−1 kj 0.79 j a calorimeter operates on which fundamental principle? the temperature change of the fluid in the calorimeter must be measured indirectly. the sum of the heat released and the heat absorbed equals the specific heat of the material. the heat released when substances react or mix equals the heat absorbed by the surrounding water. the amount of heat transferred is independent of the mass of the sample being
