Mini-Quiz: Lower and Upper Temperature Limits

by Ron Kurtus (revised 12 November 2014)

Take this Mini-Quiz to check your understanding of the lesson material.

1. Why can't a material be at exactly absolute zero?

It is against the rules of quantum mechanics

Absolute zero refrigerators are too expensive

Gases solidify at absolute zero

2. How does a thermometer measure temperature?

A thermometer measures the speed of light of the molecules

Thermometers measure heat and not temperature

Energy is transferred from the heated object to the thermometer

3. What limits the temperature of a material?

There is no limit

The greatest possible speed of the atoms or molecules

The Theory of Relatives

If you got all three correct, you are on your way to becoming a Champion in Physics. If you had problems, you had better look over the material again.
