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.

A metal rod $\mathrm{AB}$ of length $10 x$ has its one end $\mathrm{A}$ in ice at $0^{\circ} \mathrm{C}$ and the other end $\mathrm{B}$ in water at $100^{\circ} \mathrm{C}$. If a point $\mathrm{P}$ on the rod is maintained at $400^{\circ} \mathrm{C}$, then it is found that equal amounts of water and ice evaporate and melt per unit time. The latent heat of evaporation of water is $540 \ \mathrm{cal} / \mathrm{g}$ and latent heat of melting of ice is $80 \ \mathrm{cal} / \mathrm{g}$. If the point $\mathrm{P}$ is at a distance of $\lambda x$ from the ice end $\mathrm{A}$, find the value of $\lambda$.
