What is the difference between heat and temperature? Between work and energy? Between kinetic energy and potential energy?

Accepted Answer

Hi everyone for this problem. It reads do materials with high heat content always have a high temperature. Does a system always reduce its internal heat content if it performs work. And how do kinetic energy and potential energy differ? So we have a three part question here. So let's go ahead and answer part one first. Do materials with high heat content always have a high temperature. So this has to do with thermal dynamics and thermodynamics. Heat is a form of energy. Okay, So heat is a form of energy that crosses the boundary of a system due to a difference in temperature. So he always flows from high temperature too low temperature. Okay. And this flow can be from a body or a system. Okay, So it can be inferred from this statement that the system at a higher temperature has a higher heat content. So the answer to this question is yes. So for part one we're going to write yes. And that is the answer for the first question. Moving on to the second question does a system always reduce its internal heat content if it performs work? So we need an equation that relates heat and work and that equation is change in internal energy is equal to heat plus work. Okay, So if we rearrange this equation to isolate work, what we're going to get is work is equal to internal energy change minus heat. Okay, the internal heat content of the system is its internal energy while heat is the heat that is absorbed or released in a process. So this equation shows that work. Can either be performed at the expense of internal energy heat or both. Okay. And there are different processes and we can talk about those processes. So, in processes where no heat is absorbed or released, this is called a diabetic. Okay. And what this means is no heat is absorbed or released. So that's one process and work is performed at the expensive internal energy, but that's not always the case. Another process is an isil thermal process and foreign isil thermal process. The heat content of the system does not change. So we're right here, no change. Alright, So work is performed only at the expense of the absorbed heat. So the answer to this part of the question is going to be no. So for part two, we'll go ahead and write No. And that is the answer for part two. And the last part of the question. How do kinetic energy and potential energy differ. Okay, so for kinetic energy, kinetic energy is the energy of motion. Okay, So we'll go ahead and write the energy of motion and it's the energy that an object possesses due to its motion. On the other hand, potential energy, this is the energy held by an object due to its position or place. Okay, so we'll go ahead and write position or place. Okay, so this is going to be the answer for part three. How do kinetic energy and potential energy differ? Kinetic energy is the energy of motion and potential energy? Is the energy held by an object due to its position or place? Okay, that is it. For this problem, I hope this was helpful.
