The energy transferred is  28.5  j


calculation

energy is calculate  MCΔT  formula  where,

M(mass)= 6.30  grams

C(specific heat capacity)= 0.377 j/g

ΔT(change in temperature)= 32.0c- 20 c= 12 c


Energy is therefore= 6.30 g   x 0.377  j/g /c x   12 c =28.5 j

Esoterical

The energy transferred is 28.5  j.
