Mini-Quiz: Lower and Upper Temperature Limits

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

   It is against the rules of quantum mechanicsThat is correct. You sure know about temperature. Absolute zero refrigerators are too expensiveSorry, not correct. Try another button. Gases solidify at absolute zeroGood try, but not right. Select another answer.

2. How does a thermometer measure temperature?

   A thermometer measures the speed of light of the moleculesSorry, not correct. Try another button. Thermometers measure heat and not temperatureOops! Wrong answer. Re-read the question and try again. Energy is transferred from the heated object to the thermometerCorrect. You are doing better!

3. What limits the temperature of a material?

   There is no limitGood try, but not right. Select another answer. The greatest possible speed of the atoms or moleculesThat is correct. You sure know about temperature. The Theory of RelativesSorry, not correct. Try another button.
