Methods of Heat Transfer

While discussing the properties of radiation energy, Emma, Liam, and Olivia are trying to understand how it travels. What is the correct way in which radiation energy travels?

• Through conduction

• Through convection

• Through direct contact

• Through electromagnetic waves (like sunlight)

Which type of heat transfer occurs when a hot cup of coffee warms your hands?

• Conduction

• Convection

• Radiation

• Advection

Which of the following demonstrates convection in action?

• Using a microwave to heat up food

• Warming your hands by a campfire

• Heat rising from a hot pavement on a sunny day

• Gravity

What type of heat transfer occurs when a metal spoon gets hot while stirring a pot of boiling water?

• Convection

• Conduction

• Radiation

• Evaporation

When a pot of water is heated on a stove, the water at the bottom gets hot first and rises to the top, while the cooler water at the top sinks to the bottom. This continuous movement of water due to the difference in temperature is an example of...

• insulation

In a greenhouse, sunlight passes through the glass and warms the plants and soil inside. Which type of heat transfer is responsible for this warming effect?

• conduction

• radiation

• convection

• evaporation

This type of heat transfer occurs when hot and cold fluids move, causing a transfer of thermal energy.

• conduction

• radiation

• convection

• insulation
