The thermal conductivity of a rod depends on :

A

`P_(S)=P`

B

`P_(S)=(PA)/(4pir^(2))`

C

`P_(S)=0`

D

`P_(S)=sigmaepsilonT_(S)^(4)`

Text Solution

Verified by Experts

The correct Answer is:
A
Under steady state, temperature will remain constant.
Hence, there is no accumulation of energy inside `rArrP_(S)=P=` energy received form source.

A: The thermal conductivity of a body depends on its material and dimensions. R: Thermal conductivity is proportional to length and inversely proportional to area cross-section of body.

A metallic rod of cross-sectional area 20 cm^(2) , with the lateral surface insulated to prevent heat loss, has one end immersed in boiling water and the other in ice water mixture. The heat conducted through the rod melts the ice at the rate of 1 gm for every 84 sec. The thermal conductivity of the rod is 160 Wm^(-1)K^(-1) . Latent heat of ice=80 cal/gm, 1 ca=4.2 joule. What is the length (in m) of the rod?

One end of a uniform brass rod 20 cm long and 10 cm^2 cross-sectional area is kept at 100^@C . The other end is in perfect thermal contact with another rod of identical cross-section and length 10 cm. The free end of this rod is kept in melting ice and when the steady state has been reached, it is found that 360 g of ice melts per hour. Calculate the thermal conductivity of the rod, given that the thermal conductivity of brass is 0.25 cal//s cm^@C and L = 80 cal//g .

A cylindrical rod with one end in a steam chamber and the other end in ice results in melting of 0.1 g of ice per second. If the rod is replaced by another with half the length and double the radius of the first and if the thermal conductivity of material of second rod is 1/4 that of first, the rate at which ice melts in g//s will be
