Question

A red hot iron bar is dipped into 600 ml of water ( 600.g of water) which causes

Answer 1

Answer:

168277.2 J

Explanation:

m = Mass of water = 600 g

c = Specific heat of water = 4.186 J/g°C

$\Delta T$ = Change in temperature of water = $89-22=67^{\circ}\text{C}$

We know that the amount of heat lost = amount of heat gained

$Q=mc\Delta T\\\Rightarrow Q=600\times 4.186\times 67\\\Rightarrow Q=168277.2\ \text{J}$

Heat lost by the iron bar is 168277.2 J.
