Why kelvin is not a degree

R : Size of degree is eq How does intrinsic semiconductor behave at zero degree kelvin? Express this is degree Fahrenheit and Kelvin. Ratio of change in dimension to the original dimension per degree kelvin change in temperature is In which of the following sentences is the correct use of the doer K.

Absolute zero is the point at which a gas molecule has no energy. Because temperature is basically a measure of the energy and movement of molecules.

As something gets hotter its molecules gain energy and move frantically in all directions. If you heat water in a glass jar eventually the resulting steam will have so much energy that its banging against the jar will cause it to explode. As molecules can always get more energetic, things will just get hotter. However the opposite happens when something is cooled: its molecules loose energy, moving slower and slower as they do so. As a material freezes and becomes solid, its molecules are no longer moving, and there is no more energy to loose.

A temperature measure in Kelvin is denoted by the letter k. Got a question about how something is quantified Click here to ask. Not a member yet? Get Free Membership. Remember me. Forgot your login? Ask the Experts. University Departments.
