• 1.5 cal

• 10 cal

• 110 cal

• 3,000 cal

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 to the 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.
