Explanation:
A physical change is a change in which the physical properties of matter are altered. These are properties are the forms and state.
Most physical changes are easily reversible and are pure state changes.

They involve no mass change and requires little to no energy.
Examples are melting, boiling, freezing, sublimation e.t.c
The conversion between mm mercury to pascals is (1 mmHg)/(133.32 pascals).
Therefore, we use the conversion:
4.579 mmHg * (133.32 pascals/1 mmHg) = 610.5 pascals
Answer: 3.7 m − 6
Explanation: Simplify the expression.
brainliest or a thank you pls :)) <3
