A student places a warm can of fruit juice in a bucket of ice water. What happens to the particles of juice?

• The number of juice particles decreases as energy transfers via ice water.
• Energy flow decreases the size of the juice particles
• Cold energy decreases the motion of the juice particles
• Energy flow decreases the space between the juice particles

A baker has 2 identical cakes. One cake is hot (40°C) and the other is at room temperature (20°C). He places both cakes next to each other on the same 10°C plate. What happens to the energy in the cakes.

• Only the hot cake transfers energy to the plate
• The plate transfers energy to the room-temperature plate
• Both cakes transfer energy to the plate
• Neither cake transfers energy to the plate.
