Electrical Energy
Wood
Geothermal Energy
What happens to a cup of water if you place it in a freezer?
Work is done on the water, increasing its internal energy.
Work is done by the water, decreasing its internal energy.
The water transfers thermal energy to the freezer, decreasing the water's internal energy.
The water transfers thermal energy from the freezer, increasing the water's internal energy.
During an investigation, you connect two containers by a thin tube. A stopcock keeps the tube closed. One container is empty, and the other contains a gas. What will happen if you open the stopcock to connect the containers?
The gas will spread out to fill both containers as it does work on the system.
The entropy of the gas will increase, and it will spread out to fill both containers.
The internal energy of the gas will increase as it all flows into the other container.
The gas will all flow into the other container because heat is added to the system.
