The increase of pressure of a given gas is usually a result of a change in the temperature of the gas. An increase in temperature creates a corresponding increase in pressure.
Then the physical characteristic of a substance change, it is called a change in state. This most commonly occurs when a substance is heated or cooled. The states that substances are solid, liquid and gas. A common example would be water: ice (solid), water (liquid), and steam (gas).
Melting! A physical change would be to change something from Solid <--> Liquid <--> Gas
Water changing to steam is an example of a physical change, specifically a phase change from liquid to gas. This change is reversible as the steam can condense back into water under certain conditions.
No, the change from liquid to gas is a physical change, not a chemical change. In this process, the substance's molecular structure remains the same, only its physical state changes from liquid to gas.
This an example of vaporization.Vaporization is a physical change.
The sublimation of iodine crystals to produce purple gas is a physical change. This is because the change in state from solid to gas does not involve a change in the chemical composition of the substance. The purple color of the gas is due to the absorption and emission of specific wavelengths of light by the iodine atoms.
Fizzing is the result of a chemical change - a chemical reaction with gas releasing.
Physical change, because the water is only changing state, from a gas to a liquid.
Yes, heating mercury to produce mercury vapor is a physical change because no new substances are formed. The change is reversible, and the mercury can return to its original state once cooled back down.
The increase of pressure of a given gas is usually a result of a change in the temperature of the gas. An increase in temperature creates a corresponding increase in pressure.

When LPG gas burns on a gas stove, it undergoes a chemical change as it reacts with oxygen to produce heat, light, carbon dioxide, and water vapor. This is a combustion reaction. The physical change involved is the change in state of the gas from a liquid to a gaseous form as it is released from the cylinder and then burns.
A phase change is an example of a physical change, not a chemical, nuclear, or covalent change. During a phase change, the substance undergoes a change in state (solid, liquid, gas) without any change in its chemical composition.
Yes. Because the chemistry stays the same.
Melting! A physical change would be to change something from Solid <--> Liquid <--> Gas
No. It would only be a change of state if it changed from a solid to a liquid, or sublimated from a solid to a gas. There are three states. They are solid, liquid and gas. I believe that Plasma is also considered a state but I am not sure of that. Continued from previous answer. Sand is Still a solid. It is small but still solid individual pieces.
