Q1-What is meant by the statement that ," matter is particulate in nature?

Q2-Name the characterstics which determine the state of a substance ?

Q3-A gas exert pressure why?​

Answer 1

Answer:

Q1 This means that matter is made up of particles or has a particulate nature

Q2 The characteristics to define states of matter are :-

1 The amount of inter moleculer force present between the molecules.

2 Whether it has a fixed shape and volume.

Q3 A gas exerts pressure because it is a form of matter and has mass and volume even if the volume is not fixed.For example During a storm when strong winds are blowing you feel an opposing or supporting force depending on which direction you are going in.

$\huge \underline \mathfrak \red{Answer:-}$

Q1- What is meant by the statement that ," matter is particulate in nature?

Ans:- All matter is particulate in nature. This basically means that between separate bits of matter there are spaces which contain no matter. In science it is called the "atomic nature of matter."______________________

Q2- Name the characterstics which determine the state of a substance ?

Ans:-Temperature, Pressure & Purity are the factors that determine the state of a substance.______________________

Q3- A gas exert pressure why?

Ans:- The molecules are continually colliding with each other and with the walls of the container. When a molecule collides with the wall, they exert small force on the wall The pressure exerted by the gas is due to the sum of all these collisions. The more particles that hit the walls, the higher the pressure.______________________
