Question

I need help solving this Physics Heat Numerical.

Answer 1

☘☘ Here it is........ .......

>> Heat Jean by water and calorimeter= heat gain by hot object.

>> Let m (in gram) be mass of each i.e water, calorimeter and hot object.

>> Calorimeter and hot object to both are made up of copper.

☘ Let 'T' be the final temperature,

>> Heat game by water and calorimeter = m×0.09×(T-30)+m×1×(T-30)....... (i)

>> Heat loss by hot object=m×0.09×(60-T)....... (ii)

>> By equating (I) and (ii) we get..

=(T-30) ×1.09=(60-T) ×0.09... (iii)

By solving 3rd e. q we get,

T=32.3°C
