Is oxygen a chemical change or a physical?
Oxygen is a chemical element, so its presence does not involve a chemical change. It undergoes physical changes such as changes in state (gas to liquid) based on temperature and pressure.
Why is gas pressure increasing a physical change?
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.
What makes up a chemical change?
A chemical change involves the formation of new substances with different chemical properties than the original ones. This can involve the breaking and forming of chemical bonds, resulting in a change in the composition and structure of molecules. Evidence of a chemical change includes the release or absorption of energy, color change, formation of a precipitate, or production of gas.
Is forming ozone from oxygen a chemical change?
Putting oxygen in tanks (under pressure) is a physical change, not a chemical change. The chemical nature of the oxygen has not been altered, and it is possible to recover the original substance, thus it is not a chemical change.
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 pressure a physical change or chemical change?
A physical change. The chemical make up of the material is not changed. --------------------------------------------------------------------- Pressure is not a change, it is a characteristic. It is the ratio force/area.
What is needed for a solid to sublime and what changes of state occur?
pressure and the change of state is chemical
Gas under pressure physical or chemical change?
Physical change.
Is the pressure of contained neon gas increases as more gas is added to the container a chemical change?
No, the increase in pressure of contained neon gas as more gas is added to the container is a physical change, not a chemical change. This change is due to the gas particles colliding more frequently with the walls of the container, resulting in an increase in pressure without any new substances being formed.
Do you have to change fuel pressure regulator when replacing thermostat for 2002 chevy malibu?
Not unless you BROKE it.
What is needed for a solid sublime and what change of state occurs?
pressure and the change of state is chemical
How do minerals change?
THEY can change. they due to heat intense pressure and due to chemical changes. they can change their color.
What makes up a chemical?
The chemical change is made by these following:- 1. Temperature 2. pressure 3. Nature of chemical
When does the change in enthalpy equal heat in a chemical reaction?
The change in enthalpy equals the heat in a chemical reaction when the reaction occurs at constant pressure.
Some ways that density can change?
Pressure Temperature Changes in the molecular structure(chemical change)
What alters the form or phase of a sudstance but not its chemical identity?
Heat or pressure can change its form but not chemical identity.
Why is it Overheating change thermostat and hoses What is problem?
Your radiator might have a small pinhole in it, causing it to not build up pressure.
