Explanation / Answer

sol :-

1 . Change in Temperature of water (deltaT ) = A6 - A7 ( because , heat gain by water which is already given in second point )= 33.51 -21 = +8.51 degree celcius

2. Heat gained by water (q) = (4.184 J g-0C- ) m deltaT

= 4.184 J g-0C- x 100g x ( 8.51 0C)

= + 3560.584 J (heat gain by water )

3. Change in temperature of metal (delta T) = A7 -A2 = 25 - 87.21 = - 62.21 0C

4. Specific heat of metal = q(heat of metal in J ) / mass of metal (A1) x delta T

= - 3560.584 J / 57.99g x -62.21 0C ( because , +qwater = - q metal)

= 0.987 J / g 0C

Note :- Heat absorb or evolve (q) = mass of substance (m) x specific heat capacity of substance x deltaT
