Properties of matter

4. / No fixed shape and no volume; molecules have random motions.
6. / The particles which join together to make matter.
9. / Molecules vibrate about their mean position; the molecules slide over each other.
12. / The force acting normally per unit area on the surface of a body is called..
14. / The property of a body to restore its original Size and shape as the deforming force ceases to act.
15. / ‘The strain produced in a body by the stress applied to it is directly proportional to the stress within the elastic limit of the body.

1. / The force acting on unit area at the surface of a body.
2. modulus / ‘The ratio of stress to tensile strain is..’
3. / principle ‘when an object is totally or partially immersed in a liquid or up thrust acts on it equal to the weight of the liquid it displaces.’
5. / They have fixed shapes and volumes; the molecules are held tightly together.
7. / Types of Matter.
8. / _____of a substance is defined as its mass per unit volume.
10. / Principle ‘A floating object displaces a fluid having weight equal to the weight of the object.’
11. Law / Pressure applied at any point of a liquid enclosed in a container, is transmitted without loss to all other parts of the liquid.
13. / Gas occurs in its iconic state; fourth state of matter.
