1What are the 3 ways heat can be transferred?
- AInsulation, conduction, radiation
- BConduction, radiation, convection
- CConvection, conduction, irradiation
2Materials that are poor conductors of heat and that can sometimes block heat transfer are called insulators.

- BFalso
3As air is [blank_start]heated[blank_end], its particles gain energy and move [blank_start]further[blank_end] apart, becoming [blank_start]less[blank_end] dense. This hot air is less dense than cool air and so it is pushed [blank_start]upwards[blank_end] by the cooler air around it.

4Mark the correct boxes that show examples of conduction.
- ABeing warmed by an open fire
- BHeat flowing from a warm coffee cup to your hands
- CWater being heated in a saucepan
- DA saucepan getting hot on a stovetop
5Substances that transfer heat easily are known as conductors.
- AVerdadeiro
- BFalso
6Convection currents occur in
- ASolids
- BLiquids
- CGases
7Radiation transmits heat as [blank_start]invisible[blank_end] waves that travel at the speed of [blank_start]light[blank_end]. Heat travels through empty space between the Earth and the Sun. Heat from the sun cannot be transferred by [blank_start]conduction[blank_end] or convection because there are no [blank_start]particles[blank_end] to vibrate or flow in the vacuum of space.

8What happens to heat energy when it hits a surface?
- Areflected, absorbed and transmitted
- Breflected, rebounded and absorbed
- Crebounded, transmitted and infiltrated
9[blank_start]Dark[blank_end] coloured objects heat up more [blank_start]quickly[blank_end] in sunlight than lighter coloured objects. This is because they are good [blank_start]absorbers[blank_end] of radiation, whereas lighter objects [blank_start]reflect[blank_end] most of the heat and don't heat up as quickly.

10Temperature tells us how hot or cold something is.
- AVerdadeiro
- BFalso
11Heat is.....
- AA form of energy that describes the energy of all particles in an object
- Ba measure of the temperature of an object
- Chot and cold
