Question

A rod of length 1m having cross sectional area of 0.75 metre square conducts heat at 6000 joules per second then the temperature difference across the rod is if K is equal to 200 w m to the power -1 the power minus one

Answer 1

using formula ,

power = KA ∆T/∆x

where , A is cross sectional area of rod.

K is thermal conductivity , ∆T is change in temperature and ∆x is seperation between terminals of different temperatures.

here, power = 6000J/s

∆x = 1m

A = 0.75 m²

K = 200 W/m.°C

so, 6000 = 200 × 0.75 × ∆T/1

or, 30 = 0.75 × ∆T

or, ∆T = 3000/75 = 40

hence, change in temperature is 40°C
