If thermal conductivity of a material of wall varies as k = k0 (1+at), then the temperature at the centre of the wall as compared to that in case of constant thermal conductivity, will be _______.
more
less
same
depend on other factors
more
The temperature profile with variable thermal conductivity provides the detail that what effect will comes out when the conductivity of wall varies,
1.k = k0 (1+at) (thermal conductivity will be more)
2. k= k0 (1-at) (thermal conductivity will be less)
3. k = constant (thermal conductivity will be same)
Hence, the correct option is (A).
