Question

Conduction stops when all substances have

Answer 1

Explanation:

When two objects or substances that have different temperature are placed in contact with each other then there will be flow of heat from hotter object to colder object.

This transfer of heat will continue until the temperature of both the objects become equal.

For example, if a metal box has $T_{1}$ temperature that is higher than another metal box adjacent to it which has $T_{2}$ temperature. Then heat will flow from $T_{1}$ to $T_{2}$ until the temperature of both the boxes become equal to $T_{3}$.

Hence, we can conclude that conduction stops when all substances have same temperature.

Answer 2

Answer:-

It stops when the temperature of all the particles/atoms is equal.
