Liquids can flow better than gases.

Liquids expand much more than gases on heating.

What is diffusion ? Why do liquids diffuse slower than gases ? Explain by a suitable example.

Explain giving reasons : The rate of diffusion of liquids is less than that of gases.

Statement - 1 : Liquids usually expand more than solids. Statement- 2 : The intermolecular forces in liquids are weaker than in solids.

(A): Transverse mechanical waves can not propagates in liquids and gases. (R): Liquids and gases flow when acted on by shearing stress, they can not sustain shear stress

Archaebacteria can survive better than other bacteria in unfavourable conditions because of their

Why the size of the needle of a syringe controls flow rate better than the thumb pressure exerted by a doctor while administering an injection?

Statement I: A liquid will flow faster and more smoothly from a sealed can when two holes are punched in the can than when one hole is punched. Statement II: The flow becomes streamlined with two holes rather than with one hole.

Liquids are similar to gases because

Assertion : All bodies emit radiant energy whether they are solid, liquid or gases. Reason : Black bodies absorb and emit radiant energy better than bodies of lighter colours.
