What part of earths surface involves both chemical and physical change?
what involves both chemical and physical change on earths surface
Is heating ammonium chloride crystal a physical or chemical change?
Heating ammonium chloride crystal is a physical change, as it only involves a change in state from a solid to a gas without forming any new substances.
Is heating sodium chloride with a Bunsen burner a chemical change?
No. It is a physical change. It only melts.
What are the 3 changes in the state of matter that involve heating and the 3 that involve cooling?
Freezing, condensation involves in cooling Melting, evaporation, boiling, sublimation, and the change from gas to plasma needs heating.
What heats Earth's surface and causes water to change states?
The Sun heats Earth's surface through radiation. This heating causes water to change states from liquid to vapor through the process of evaporation.
Is heating cupric nitrate a physical or chemical change?
Heating cupric nitrate is a chemical change because it involves the decomposition of cupric nitrate into copper oxide, nitrogen dioxide, and oxygen. This change results in the formation of new substances with different properties from the original cupric nitrate.
Is heating an iron nail a physical or chemical change?
Heating is a physical change.
Is heating copper sulfate crystals a chemical change?
Heating copper sulfate crystals is a physical change because it only involves a change in state from solid to liquid or gas, without altering the chemical composition of the substance. Chemical changes involve the rearrangement of atoms to form new substances with different properties.
Is heating hydrated sodium carbonate powder chemical or physical change?
Heating hydrated sodium carbonate powder to remove water molecules is a physical change because it does not change the chemical composition of the substance. The process involves a phase change from solid to liquid (water loss) and does not result in the formation of new substances.
Is heating ammonium dichromate a chemical or physical change?
Heating ammonium dichromate is a chemical change because it results in a new substance being formed - typically chromium(III) oxide, nitrogen gas, and water vapor. This change is irreversible and involves the breaking and forming of chemical bonds.
What phase change involves gas becoming a solid?
Vaporization (in mass, at the boiling point) or evaporation (on the surface and under boiling point).
Why is it heating a platinum wire in air is a physical change?
Heating a platinum wire in air is a physical change because it does not change the chemical composition of the platinum wire. The heat causes the platinum wire to expand and may change its physical appearance, but it remains chemically the same.
