What is the effect of pressures on boiling point of water ?
What is the effect of pressures on boiling point of water ?
Temperature of boiling water is $100^{\circ} \mathrm{C}$ and of steam is also $100^{\circ} \mathrm{C}$ but steam has $22.6 \times 10^{5} \mathrm{~J} \mathrm{~kg}^{-1}$ more heat than boiling water. Hence, it is burnt more by steam than boiling water.
