Question

Water is better thermometric liquid

• A. True
• B. False

Answer 1

The correct option is B False

The above statement is false.

Water can't be used as thermometric liquid as:

(i) It sticks to the glass

(ii) It is transparent, and hence difficult to read its level through

(iii) It is volatile and hence vapors apply pressure on the surface thereby affecting reading

(iv) It is a poor conductor of heat.

(v) its expansion is not uniform.

(vi) It freezes at 0°C and boils at 100°C and hence range is not very wide.
