Lesson Review: Heat and Temperature

Grade 9 General Science

Heat is the energy caused by the movement of particles in matter

Temperature is a measurement of this energy. It can be measured using one of 3 scales:

Degrees C ^oC

Degrees F ^oF

Kelvin K

Heat vs. temperature

We measure temperature using an instrument called a thermometer

Mercury Thermometers are able to read higher temperatures but mercury is a toxic substance

Alcohol has a relatively low boiling point but can be coloured making it easier to see.

​

Heat has 3 modes of movement:

Conduction: through physical contact (usually between solid objects)

Convection: through the movement of particles (usually between fluid objects)

Radiation: through electromagnetic waves (across an empty space)
