Question

(a) What is matter? Write two properties of solids and two properties of liquids. (b) Ramesh took two beakers A and B containing hot water and cold water respectively. In each beaker he dropped a crystal of copper sulphate. He kept the beakers undisturbed. After some time what did he observe? Why?

Answer 1

anything that has mass and occupies space is called a matter.
properties of solid:
1) they have distinct boundries and definite shape.
2)they donot flow.
properties of liquid:
1) they take the shape of container.
2) they flow.

Raman will observe that in beaker A the rate of diffusion of copper sulphate crystal is maximun than in beaker B containing cold water because in beaker A temprature of liquid is high so when temprature increases , the rate of diffusion increases.

Answer 2

anything that occupies space and have some mass and volume is known as matter.

two properties of solid are,
it has definite shape and distinct boundaries they have a tendency to maintain their shape
two properties of liquid are,
have no definite shape and not disturb boundaries if I fill it in a container it will take shape of the container.
