1. A light, shiny surface absorbs more heat and keeps the heater warm.

2. A light, shiny surface reflects more infrared radiation downwards.

3. A dark, matt surface reflects more heat towards people nearby.

4. A dark, matt surface prevents heat from rising into the air.

1. The vacuum prevents conduction and convection because there are no particles to transfer heat.

2. The vacuum reduces heat transfer by reflecting heat back into the flask.

3. The vacuum allows heat to escape more quickly by radiation.

4. The vacuum increases air pressure, which slows down energy transfer.

1. It heats up and cools down quickly.

2. It requires a lot of energy to change its temperature by a specific amount.

3. It has a low melting point.

4. It stores a small amount of internal energy per degree of temperature change.

1. The energy is used to break intermolecular bonds.

2. The energy is lost to the surroundings.

3. The particles are not moving.

4. The substance is absorbing energy to increase its temperature.

1. The energy required to change the state of a substance from solid to liquid at a constant temperature.

2. The energy required to raise the temperature of 1 kg of a liquid by 1°C.

3. The energy required to change the state of 1 kg of a substance from liquid to gas at a constant temperature.

4. The total energy stored in the bonds of a liquid.
