Match the following Column I Column II A Rate of variation of density \(\left( \rho \right)\) is zero for water P Less than \(4^\circ C\) B Least volume of water Q Coexistence of three phases of a substance C Triple point R Equal to \(4^\circ C\)
The density of water increases from \(0 \rightarrow 4^{\circ} \mathrm{C}\) and reaches maximum at \(4^\circ \,C\). After crossing \(4^\circ \,C\) it decreases. So rate of variation of density is zero at \(4^\circ C\)

A body is floating inside a liquid. If we increase temperature then what changes occur in buoyancy force? (Assume body is always in floating condition)
1 Buoyancy force will increase
2 Buoyancy force will decrease
3 Buoyancy force remains constant
4 Cannot be force calculated from given statement
Explanation:
Body is in equilibrium, buoyancy force will balance the weight of the body. \(m g=F_{B}\) The gravitational force does not change with change in temperature. So Buoyancy force remains constant. By increasing temperature density of liquid decreases so volume of body inside the liquid increases

The substance which has negative coefficient of thermal expansion is
1 Water
2 Aluminum
3 Iron
4 Invar steel
Explanation:
If we heat water present at \(0^{\circ} \mathrm{C}\) then it contracts until it reaches \(4^{\circ} \mathrm{C}\).
