Science: U2L2- How is Energy Transferred?

Energy transfer in a solar panel

Light waves from the sun are absorbed by the panel, transferring energy to it.

Example of heat transfer by touching an object

Warming hands on a cup of hot chocolate.

Material through which sound waves travel most slowly

Air

Determining which cup of water has the most energy

Cup 2’s reading, because a higher temperature indicates more energy.

Direction of energy transfer when an ice cube melts in warm tea

Heat transfers from the warm tea to the cooler ice cube and the glass.

Source and transformation of energy in a solar cooker

Light energy from the sun travels in waves to the cooker and transforms into heat energy to cook food.
