8G Unit 7 Heat Transfer Test Review

What is the definition of CONDUCTION?

• When heat is transferred from objects like rays of light or electromagnetically.
• a  hot liquid or air that  expands, becomes less dense, and rises or becomes more dense, and sinks.
• When heat transfers from objects that are touching.
• When heat transfers through the heater or AC in your house.

What kind of heat transfer happens when the sun is heating your body?

• Conduction
• Radiation
• Convection
• Density

Warm air rises and the cool air sinks demonstrates this type of heat transfer.

Transfer of thermal energy through "space"

• conduction
• convection
• radiation

During a heat transfer demonstration, students observed water being pumped around a closed loop in an engine. The moving water carries heat from the hot engine to the radiator. Which type of heat transfer is involved when the cooler water absorbs heat while in contact with the hot engine?

• Convection
• Conduction
• Insulation
• Radiation

What happens when ice cubes melt in a glass?

• Heat travels from the ice to the warmer water.
• No energy is transferred.
• Heat is transferred from the warmer water to the ice cubes.
• The water warms up due to the humidity
