# Chemical change: Identify, describe, and apply principles of heat

### Subject outcome

Subject outcome 6.1: Identify, describe, and apply principles of heat.

### Learning outcomes

- State the first law of thermodynamics: principle of conservation of energy.
- Define temperature and measure temperature using thermometers (Kelvin and Celsius scales) and colours of heated objects.

- Understand what heat is.
- Understand the three scales of measurement used to measure heat.
- Understand that heat can be transferred by:
- convection
- conduction
- radiation.

### Unit 3 outcomes

By the end of this unit you will be able to:

- Understand what specific heat is and how to calculate heat capacity.
