Question

A closed system includes a cup of warm water and an ice cube that was just placed inside of it. Which statement describes
the energy of the system over time? (1 point)
The total energy of the system will decrease as the ice causes the warm water molecules to lose kinetic
energy
The total energy of the system will stay the same as kinetic energy from the warm water increases the
kinetic energy of molecules in the ice.

energy
The total energy of the system will stay the same as kinetic energy from the warm water decreases the
kinetic energy of molecules in the ice.

Answer 1

In a close system, the total energy of the system will decrease as the ice causes the warm water molecules to lose kinetic energy.

What is a close system?

It is a system that is enclosed and would not allow the flow of any material form itself to another or form another system to itself.

A close system also does not allow transfer of energy between system.

Therefore, the total energy of the system will decrease as the ice causes the warm water molecules to lose kinetic energy.
