O Atoms gain energy as a gas changes to a solid.
O Atoms gain energy as a gas changes to a liquid.
O Atoms lose energy as a gas changes to a solid.
O Atoms lose energy as a gas changes to a liquid.

Atoms lose energy as a gas changes to a solid. How is energy related to the change of state represented by the model? Atoms gain energy as a solid changes to a liquid.

Explanation:

Cardiac is your heart muscle, so C. Skeletal is the muscle on your bone so A. And smooth is the digestive muscle so B. 

To remember this, Cardiac and Cardinal are alike in name and cardinals are red.
Skeletal muscle connects to bone, your skeleton is bones.
The inside of your digestive system is smooth, thus smooth muscle

Hope this helps :)
