25g of a solid requires 8550j of heat to melt . calculate latent heat of fusion of the substance?

we know that heat supplied is given as

Q = mL

or latent heat

L = Q/m

here,

m = 25g = 0.025 kg

Q = 8550 J

so,

L = 8550 / 0.025

thus, we have

L = 342 kJ/kg

  • 2

m = 25 g , Q = 8550J

Since, Q = m x L

Therefore, L =Q/m

So,

Latent heat of fusion of thr substance = 8550 / 25 J/g = 342 J/g (Ans)
