Answer:
thoroughly scrutinizing, especially in a disconcerting way.
Explanation:
Answer:
Explanation:
Given
Temperature of solid
Einstein Temperature
Heat Capacity in the Einstein model is given by
Substitute the values
Answer:
d) Is the thermal conductivity of the medium constant or variable.
Explanation:
As we know that
Heat equation with heat generation at unsteady state and with constant thermal conductivity given as
With out heat generation
In 2 -D with out heat generation with constant thermal conductivity
Given equation
So we can say that this is the case of with out heat generation ,unsteady state and with constant thermal conductivity.
So the option d is correct.
d) Is the thermal conductivity of the medium constant or variable.
