The steam point on Fahrenheit scale is :

1. 273° F
2. 100° F
3. 213° F
4. 212° F

Celsius and Fahrenheit scales are related as :

1. $\dfrac{\text{C}}{5}$ = $\dfrac{\text{F - 32}}{9}$

2. $\dfrac{\text{C}}{9}$ = $\dfrac{\text{F + 32}}{5}$

3. 5C = $\dfrac{9}{\text{F + 32}}$

4. $\dfrac{\text{C}}{5}$ = $9(\text{F + 32})$

On heating, liquids expand …………… than solids and gases expand …………… than liquids.

1. more, less
2. less, more
3. more, much more
4. less, less

Water is cooled from 4°C to 0°C. It :

1. contracts
2. expands
3. first contracts, then expands
4. first expands, then contracts.
