Question

An iron ball of mass 3kg at 150 ℃ is dropped in 7kg of water at 0℃. What is their final temperature when thermal equilibrium is attained?

Answer 1

Answer:

Explanation:

a heating coil rated at 1000 watts is used to boil off 0 5kg of water what is the time taken to boil the water; A hot iron ball of mass 0 2 kg is added into 0 5 kg of water at 10^0C The resulting temperature is 30^0C calculate the temperature of hot ball specific heat capacity of iron = 336 J /kg K and specific heat capacity of water = 4 2 x 10 .
