I believe the change of state shown in the model is deposition.
Deposition is a process in which gases change phase and turns directly in solids without passing through the liquid phase. It is the opposite of sublimation.
One of the major difference between gases and solids is the distance between molecules; in gases the inter molecular spaces are large, while in solid they are very small, making solids be the most dense, with closely packed molecules. This is evident in the diagram, the phase changed from gases to solids.
Answer:
option d is right
Explanation:
More precipitation occurs near the equator because it is a tropical area. Mountains receive less than 15 inches of rain per year while the equator area receives a lot of rain. This is due to the very hot weather.
Answer:
OB. Energy transfer would occur between the copper bars and the surroundings.
Explanation:
We define an isolated system as a system in which there is neither exchange of material nor energy while an open system is one in which materials and energy can be exchanged with the environment.
Given an open system consisting of two copper bars at different temperatures, energy will not only be exchanged between the copper bars but also between the copper bars and the environment.
Answer:
Some signs of a chemical change are a change in color and the formation of bubbles. The five conditions of chemical change: color change, formation of a precipitate, formation of a gas, odor change, temperature change.
