Question

Give reasons :
(i) liquids show more expansion than solids
ii) mercury is commonly used in thermometers​

Answer 1

Explanation:

1)Liquids expands are expands more than solids because the “bonds between” distinct molecules are less tight. This is the 'principle' behind thermometers for liquid-in-glass.

2)Mercury is the only one in liquid state at room temperature. It's used in thermometers because it has high coefficient of expansion. Hence, the slightest change in temperature is notable when it's used in a thermometer. It also has a high boiling point which makes it very suitable to measure higher temperatures

Answer 2

Answer:

1)atoms in liquids are loosely packed than solids

2)It has high coefficient of expansion
