Gas under pressure is a physical change not a chemical change because the gas is not being affected chemically (atoms are not bonding to other atoms and etc.). Pressure only forces the gas particles to be closer together, possibly reverting them to liquids if the temperature is low enough.
What else can I help you with?
Is chlorine gas liquefies at - 35 degree celsius under normal pressure a chemical or a physical change?
The liquefaction of chlorine gas at -35 degrees Celsius under normal pressure is a physical change. This is because the change in state from a gas to a liquid does not alter the chemical composition of the substance, only its physical state.
Is the change of plants remains into coal a physical or a chemical change?
The change of plant remains into coal is a chemical change. This process, known as coalification, involves the chemical alteration of organic material under high temperature and pressure over millions of years, leading to the formation of coal with different properties.
Is a bruise a physical or chemical change?
Bruises are the consequence of a physical action.
Is decompositon a chemical property?
A physical property is part of the make up of something that has a physical mass. No decomposing is not a physical property but rather both a physical change and a chemical change hence changing the chemical properties . The physical change is when the mass changes due to the brake down of the chemical and physical properties.
Is brittleness chemical or physical change?
Brittleness is considered a physical change. It is a change that can be felt, and interacting with it does nothing to change it into something else.
Gas under pressure physical or chemical change?
Physical change.
Is chlorine gas liquefies at - 35 degree celsius under normal pressure a chemical or a physical change?
The liquefaction of chlorine gas at -35 degrees Celsius under normal pressure is a physical change. This is because the change in state from a gas to a liquid does not alter the chemical composition of the substance, only its physical state.
Is chlorine gas liquefies at 35 degree celsius under normal pressure a chemical or a physical change?
The liquefaction of chlorine gas at 35 degrees Celsius under normal pressure is a physical change. It involves a change in the state of the substance (from gas to liquid) without altering its chemical composition.
How do the physical and chemical properties properties of the elements change?
periodically within a group
Is formation of gas a chemical or physical change?
Physical, because the gas is still the same gas, just under pressure Some gasses may undergo spontaneous chemical reactions under very high heat and/or pressure. For example ozone under high pressure will fairly rapidly decay into oxygen gas.
Is the change of plants remains into coal a physical or a chemical change?
The change of plant remains into coal is a chemical change. This process, known as coalification, involves the chemical alteration of organic material under high temperature and pressure over millions of years, leading to the formation of coal with different properties.
Is freezing point a physical property or physical change?
Freezing point is a physical property. It is the temperature at which a substance changes from a liquid to a solid state under standard atmospheric pressure. Physical changes involve a change in state without altering the chemical composition of a substance.
Is rusting a phsyical change?
Rusting is a chemical change because under it iron goes under oxidation and oxidation is a chemical process. Also, a physical change can be reversed but a chemical change cannot and rusting cannot be reversed. Hence also rusting is a chemical change.
Is a photosynthesis an example of a chemical change and not under physical change?
Chemical because the molecules get rearranged making a entirely new molecule
How is a chemical and physical change similar?
they are both categorized under characteristic properties.
Is a bruise a physical or chemical change?
Bruises are the consequence of a physical action.
Is boiling point a chemical property?
Yes, boiling point is a chemical property. It is the temperature at which a substance changes from a liquid to a gas phase under standard atmospheric pressure, and is characteristic of that substance, making it a chemical property.
