Vivian placed an ice cube in a cup of warm water. The following picture shows her investigation:

Which statement describes the energy transfer taking place?

• Heat is transferred from the ice cube to water by radiation

• Heat is transferred from water to the ice cube by radiation

• Heat is transferred to from the ice cube to the water by conduction

• Heat is transferred from the water to the ice cube by conduction

Conduction happens as energy flows from a warmer object to a colder object. Which of the following is an example of conduction?

• warmer air is pushed upward and out of the way by cooler air

• electromagnetic radiation transfers energy from the sun to Earth

• dense water sinks to the ocean floor and less dense water moves towards the surface

• cooler air molecules come in contact with the warm ground, causing energy to be passed to the air
