The quantity of heat which crosses unit area of a metal plate during conduction depends upon

$A$ piece of glass is heated to a high temperature and then allowed to cool. If it cracks,a probable reason for this is the following property of glass:

The heat is flowing through a rod of length $50 \ cm$ and area of cross-section $5 \ cm^2$. Its ends are respectively at $25^\circ C$ and $125^\circ C$. The coefficient of thermal conductivity of the material of the rod is $0.092 \ kcal/m \cdot s \cdot ^\circ C$. The temperature gradient in the rod is

Why are snow particles poorer conductors of heat than ice?

Write a note on a double-walled flask or a thermos.

In a steady state of thermal conduction,the temperatures of the ends $A$ and $B$ of a $20 \, cm$ long rod are $100^\circ C$ and $0^\circ C$ respectively. What will be the temperature of the rod at a point at a distance of $6 \, cm$ from the end $A$ of the rod (in $^\circ C$)?
