Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]

To change from a solid to a gas, ____ thermal energy. This change is called ____ To change from a gas to a solid, ____ thermal energy. This is called ____

A	Add, depositing, remove, sublimating
B	remove, depositing, add, sublimating
C	Remove, sublimating, add, depositing
D	Add, sublimating, remove, depositing

Explanation:

Detailed explanation-1: -Sublimation: The change of a solid directly to a gas. Energy must be added. Think: As dry ice is exposed to a warmer temperature (more energy) it will begin to look like its steaming.

Detailed explanation-2: -Changes of State. Particles require heat energy to change state between a solid, liquid and a gas. As heat energy is added, the particles gain more heat energy until they undergo the process of changing state, at which point their temperature remains constant.

Detailed explanation-3: -Sublimation is a type of phase change that takes place when a solid turns directly into a gas, skipping the liquid phase.

Detailed explanation-4: -Liquid-gas changes include evaporation (liquid to gas by adding thermal energy) or condensation (gas to liquid by removing thermal energy). Solid-gas changes include sublimation (solid to gas by adding thermal energy) or deposition (gas to solid by removing thermal energy).
