Calculate the heat energy required to melt a 20g block of silver at 20°C. The melting point of silver is 960°C. It's specific heat capacity is 2.34×10^2 and its heat of fusion is 8.83×10^4

Answer:Mass of the block m = 20 g
Temperature difference Ît = t2 - t1 = 960 - 20 =9400
Specific heat of silver S= 0.056 cal/g_0C
Latent heat of fusion L = 21.1 cal/g
Heat energy required Q = mSÎt + mL
= (20*0.056*940) + (20*21.1)
= 1052.8 + 422
=1474.8 cal
Explanation:just subtitute the values you have in place of the cones i have in cal.
