Physical Characteristics of Pure Water
Boiling point = \(100^\circ \text{C}\)
Freezing point = \( 0^\circ \text{C}\)
Colourless
Density = \(1\text{ g cm}^{-3}\)
Effects of absorption and release of heat on the state of water
1) Heat is absorbed
SOLID \(\begin{aligned} &\text{melting}\\ &\quad\rightarrow \end{aligned}\) LIQUID \(\begin{aligned} &\text{evaporation/boiling}\\ &\quad\rightarrow \end{aligned}\)GAS
2) Heat is released
GAS \(\begin{aligned} &\text{condensation}\\ &\quad\rightarrow \end{aligned}\) LIQUID \(\begin{aligned} &\text{freezing}\\ &\quad\rightarrow \end{aligned}\) SOLID
