## Heat vs. Temp

isochoric/isometric: $\Delta V = 0$
isothermal: $\Delta T = 0$
isobaric: $\Delta P = 0$

### Heat vs. Temp

What is the difference between heat and temperature?

Hi, Ryan,
Heat is the energy that is transferred between molecules. Temperature is not energy; it is simply a measure of how fast the molecules are moving: how “cold” or “hot” they are.

### Re: Heat vs. Temp

you can also see this with the heating curves. for example, when ice is melted into liquid water, there is a plateau where there is heat being added but the temperature remains constant. this means molecules are transferring energy faster, but there is not a significant increase in the how fast the molecules are moving to cause another phase change yet.

The heat of an object is the total energy of all the molecular motion inside that object. Temperature, on the other hand, is a measure of the average heat or thermal energy of the molecules in a substance.

### Re: Heat vs. Temp

Temperature indicates the random motion of particles.
Heat is the transfer of energy due to a temperature difference.

In summary, Temperature represents particle motion, and Heat represents energy transfer.

In short, heat is energy while temperature itself is not and it measures the speed of the molecules moving about.

Heat refers to the transfer of energy between molecules which is why heat is measured in Joules, whereas temperature merely refers to the random motion of molecules.

### Re: Heat vs. Temp

Temperature, essentially, measures heat, since heat is the action/energy (of particles moving) and temperature is a measurement (Kelvin, Celsius, etc.).

### Re: Heat vs. Temp

So is it correct to say that heat is directly proportional to temperature?
