Liquified Natural Gas (LNG) is natural gas which has undergone a phase change from gas to liquid in order to reduce volume so that it may be economically exported across international borders.
The physical changes that happen in green plants are the changes in appearance. The difference between a sprout and a full grown plant is a physical change.
Physical changes are melting and boiling in this case; fire is a combustion, a chemical change.
You can tell the difference by knowing that a physical property changes shape and that a chemical property changes the substance.
A physical change is when a substance changes, but still keeps its identity. When a chemical change occurs, the substance changes its identity.
the difference between a physical change and a chemical change is that a physical change is usually reversible whilst a chemical change is not reversible.
the difference between a physical change and a chemical change is that a physical change is usually reversible whilst a chemical change is not reversible.
The relationship between physical activity and cardiovascular activity is that physical activity changes body organs, which results in improved cardiovascular fitness. hope this helps :)
Physical changes is change in property. Ex) change from solid to liquid....ice to water. Chemical change changes to different substances. Ex) rotting of fruit.
A physical change changes the physical properties of an element like color where chemical changes change the chemical properties of an element and usually can't be undone.
Physical Changes
Both chemical and physical changes involve a transformation of matter. In physical changes, the substance's chemical composition remains the same, while in chemical changes, new substances are formed as a result of a chemical reaction. Both types of changes involve the absorption or release of energy.
Physical changes are changes that affect the form of a chemical substance, such as changes in state or shape, without changing its chemical composition. Chemical changes, on the other hand, result in the formation of new substances with different chemical properties. Physical changes are usually reversible, while chemical changes are often irreversible.
