How does conduction occur in metals?

• Heat absorption from the surroundings

• Movement of protons within the metal structure

• Reflection of light within the metal

• Movement of free electrons within the metal structure

Explain how convection occurs in liquids.

• The liquid expands and becomes less dense, causing it to rise

• The colder part of the liquid rises and the warmer part sinks

• The liquid becomes more viscous and moves in a straight line

• The warmer part of the liquid rises and the colder part sinks, creating a circular motion.

What are the factors that affect convection in liquids?

• Difference in temperature, difference in density and gravity

• Difference in humidity, difference in viscosity and magnetism

• Difference in velocity, difference in surface tension and friction

• Difference in color, difference in pressure and volume

How does solar radiation contribute to the temperature of the Earth?

• The sun's radiation keeps the Earth's temperature constant.

• The sun's radiation heats the Earth's surface.

• The sun's radiation has no effect on the Earth's temperature.

• The sun's radiation cools the Earth's surface.

Can you give an example of convection on land?

• Wind blowing between trees

• A car engine running

• The sun heating the ground

• Boiling water in a pot

Explain how convection occurs in the atmosphere.

• Convection is caused by the attraction of gravity on air molecules

• Cold air rises and warm air sinks

• Convection occurs due to the rotation of the Earth

• Warm air rises and cool air sinks

How does heat transfer occur when you touch a hot object?

• Absorption

• Reflection

• Convection

• Conduction

Describe a scenario where convection is observed in a cooking pot.

• Convection occurs in a pot when the water remains still and does not move at all.

• Convection occurs in a pot when the water turns into ice instead of boiling.

• Convection occurs in a pot when the water evaporates without any movement.

• Convection occurs in a pot when heating water causes the formation of a convection current, with warmer water rising upwards and cooler water sinking downwards.
