Lily is doing an experiment with a substance in a sealed jar. At first, the substances molecules are moving around each other. Ehat will happen to lily's substance if she transfers energy into the substance and causes a phase change

the entropy and entalpy of the system will increase

Explanation: adding energy to the system will cause the molecules within the jar to absorb more energy, this excitation will bring about more movement of the molecules and more collision between molecules. Also, the molecules will try to move further apart from themselves with increased degree of randomness.

The Most likely substance Lily was  experimenting on would be a Liquid, since it molecules are moving around each other. If energy is being transferred to the substance leading to a phase change it will vaporize to become a gas.

Explanation: The Most likely substance Lily was  experimenting on would be a Liquid, since it molecules are moving around each other. If energy is being transferred to the substance leading to a phase change it will vaporize to become a gas. The energy supplied to the substance raises the kinetic energy of the substance's molecule thereby making them collide with one another and the wall of the jar. As the kinetic energy of the molecule increases they tend to break away from each other thereby moving randomly as most gaseous molecules does.

go to the police department   they will get that person in touch with cps
