What are six forces that bring about the weathering of rock?
The six forces that bring about the weathering of rock are mechanical weathering (e.g. frost action, root wedging), chemical weathering (e.g. oxidation, dissolution), biological weathering (e.g. plant roots, burrowing animals), temperature changes, pressure changes, and erosion by wind, water, or ice.
Water is boiled in a pan on a stove The state of matter of the water changes from gas to liquid or liquid to gas?
The state of matter changes from liquid to gas when water is boiled in a pan on a stove.
Why are most physical changes reversable?
Most physical changes are reversible because they involve only changes in the physical state or appearance of a substance, rather than its chemical composition. Reversible changes usually involve processes like melting, freezing, dissolving, or changes in shape, which can be easily reversed by applying the appropriate conditions to change the substance back to its original state.
AT 115 degrees sulphur changes into a?
At 115 degrees Celsius, sulfur changes into a yellow liquid state.
Which of the following happens when ice melts?
1st it "changes" into water, and if heated long enough, at high enough temperature, it "changes" to steam, then, it eventually evaporates.
What are the six changes of state?
The six changes of state are: melting (solid to liquid), freezing (liquid to solid), vaporization (liquid to gas), condensation (gas to liquid), sublimation (solid to gas), and deposition (gas to solid).
How substances changes from one state to the other state?
through changes of energy
Why are changes of state chemical changes?
They aren't; a change of state is a physical change
Are state changes chemical or physical changes?
Physical Changes
When water is boiled it changes?
When water boils it changes from a liquid state to a gaseous state.
What Matter changes state because of?
Matter changes state because of pressure and temperature.
How are the state changes of water similar to the state changes in most other substances?
These changes of state are: solid to liquid, liquid to gas, gas to liquid, liquid to solid, solid to gas, gas to solid. The majority of substances have these state of matter changes.
Changes in state of water?
The only changes of state in pure boiling water is from liquid to gas.
How the temperature can bring can bring about changes in the state of matter?
how temperature can bring about changes in the state of matter
What happens to water as it changes state?
The density changes.
Are the changes in the state of matter chemical changes?
No, changes in state of matter (such as melting, freezing, boiling) are physical changes, not chemical changes. Chemical changes involve the formation of new substances with different chemical properties.
What two conditions can change the state of matter?
1) melting-solid state changes into liquid state and 2)freezing-liquid state changes into solid state
