Question

how can physical properties of matter be changed ?​

Answer 1

Answer:

physical property can be changed by heating or cooling

Explanation:

for example:

ICE

it can be changed to water by heating and water can again be changed into ice by cooling it.

Answer 2

$\mathfrak{\large{\underline{\underline{Answer:-}}}}$

Physical properties of Matter :-

The physical properties can be defined as which properties which can not change the basic composition of matter is called physical properties.

The physical properties of matters are :-

Melting points, boiling points, colour, electrical conductivity and physical states at a given temperature.

The physical properties of Matter can be changed by following methods:-

The physical states of matter can be changed by either increasing or decreasing the temperature and pressure of the matter.

When we increase the temperature of solid it melts and converted into liquid after further heat it get converted in to vapour.

Now, by applying pressure or decreasing temperature vapours get converted in to liquid.

hence, by increasing or decreasing the pressure or temperature of matter we can change its physical properties.
