Question

True or false
1. Heat cannot be transmitted in solid substances.​

Answer 1

True because in solids the heat is transferred by conduction

Answer 2

Heat cannot be transmitted in solid substances.​ - True

The above-given statement is correct and in the solid, the heat is transferred by conduction, not by Transmission

where:

Transmission

Transmission is the transfer of the heat from one place to the other place where the object is moved from one place to another place.

Conduction

Conduction is the process of transferring the heat by the vibrating of the molecules in the solid.

So in the solid, the heat is transfered as when heat is provided to the solid then the kinetic energy of the atom is increased and atom starts vibrating due to which the heat is transfered.
