Question

physical state of matter can be changed by changing ________ and __________​

Answer 1

Answer:

By changing pressure. and

By changing temperature

Answer 2

Answer:

Physical state of matter can be changed by changing Temperature and Pressure.

Explanation:

As we all know, there are mainly 3 states of matter. They are:

1. Solid state
2. Liquid state
3. Gaseous state.

The interconversion of these states of matter can by done by increasing or decreasing the temperature and pressure.

Let us understand this by taking a simple example.

The examples of solid state, liquid state and gaseous state can be taken as: → Ice cube, water and steam respectively.

By increasing the temperature and pressure;

• Ice cube can be converted into water.
• Furthermore, water can be converted into steam.

By decreasing the temperature and pressure;

• Steam can be converted into water
• On further decreasing, water can be converted into ice.
