Hello, in this first part it is related to this thermal conductivity.
00:05
So here as we know that, that is for this thermal conductivity of any material, it is a measure of the ability to conduct the heat.
00:17
It is commonly denoted as k, it is there.
00:23
So heat transfers occurs at a lower rate in the materials of the lower thermal conductivity than in the materials of the higher thermal conductivity.
00:31
So, that means the rate at which the heat is transferred by the conduction through a unit cross -section area of a material when the temperature gradient exists perpendicular to the area.
00:43
So therefore here, we will say that is this material's ability to transmit or conduct heat.
00:50
It is a thermal conductivity.
00:52
So hence here this option b is the right answer.
00:59
Now, here as we know that, that is delta g is equal to delta h minus...
