How is energy transferred calculated
Webenergy transfer, the change of energy from one form to another. According to the first law of thermodynamics, energy can be neither created nor destroyed; in other words, the total energy of the universe remains constant. For example, when a block slides down a slope, the potential energy of the block sitting at the top of the slope is converted to the kinetic … Web17 jun. 2024 · Calculate the heat transferred to the water. Use the specific heat of water in Table 1: Qw = mwcwΔT = (0.250kg)(4186J / kgoC)(60.0oC) = 62.8kJ. Calculate the heat transferred to the aluminum. Use the specific heat for aluminum in Table 1: QA1 = mA1cA1ΔT = (0.500kg)(900J / kgoC)(60.0oC) = 27.0kJ.

WebThe net work is the change in kinetic energy of the object, which in this case would be zero because the velocity does not change (remember KE is 1/2mv^2). But the work that we have done on the object is not zero because we are referring only the force we exerted, not the net force. We could also ask how much work gravity did on the object, and ...
