What Does Thermal Energy Measure

Measuring Thermal Energy

Thermal energy is energy associated with random motion of molecules. It is indicated by temperature which is the measure out of the relative warmth or coolness of an object.

A temperature calibration is determined past choosing two reference temperatures and dividing the temperature difference betwixt these two points into a certain number of degrees.

The 2 reference temperatures used for about common scales are the melting indicate of water ice and the boiling signal of water.

On the Celsius temperature scale, or centigrade calibration, the melting point is taken equally 0°C and the boiling point equally 100°C, with the difference between them existence equal to 100 degrees.
On the Fahrenheit temperature scale, the melting point is taken as 32°F and the humid point equally 212°F, with the difference betwixt them being equal to 180 degrees.

It is important to realize, notwithstanding, that the temperature of a substance is non a mensurate of its heat content, but rather, the average kinetic energy of its molecules resulting from their motions.

Below is a 6-ounce cup with hot water and a 12-ounce cup with hot water at the same temperature.

Do they have the same heat content?
Exercise they take the same amount of free energy?

A 6 ounce cup and a twelve ounce cup are both filled with 85 degree water.

Conclusion: They practise NOT have the same heat content. Since water in the ii cups is at the same temperature, the boilerplate kinetic energy of the molecules in the cups is the same; however, the 12 ounce loving cup has twice as many molecules when compared with the 6 ounce loving cup and thus has the greater full motion or rut free energy.
