An ice cube floats in warm water in a container placed outside on a hot sunny day. Describe the direction of thermal energy flow and how long this flow will occur.*

• The heat arrows will point from the sun to the water and ice cube and from the water to the ice cube. It will continue until the thermal energy of all items is equal

• The heat arrows will point from the sun to the water and ice cube and from the water to the ice cube. The flow will continue for no more than five minutes

• The heat arrows will point from the sun outward. It will continue until the thermal energy of all items is equal

• The heat arrows will point up from the ice cube and out into the air. It will continue until the thermal energy of all items is equal
