the heat of fusion of aluminum is 95 cal/g. calculate how many grams of aluminum(already at its melting point) could be melted with 1,265,730 cal of energy (round your answer to two decimal places)

Given

Lf=latent heat of fusion  of Al = 95 cal/g

Q = 1,265,730 cal

Required

mass of Aluminium

Solution

The heat to change the phase can be formulated :

Q = m.Lf (melting/freezing)

Input the value

1,265,730 cal = m . 95 cal/g

m = 1,265,730 cal : 95 cal/g

m = 13323.47 g

the earth would become to overheated and everything alive on it will eventually die from overheating. plants will eventually die as well, water will evaporate, and it will be nothing but a hot planet without anything living on it.

in the analysis of systems that involve fluid flow, we frequently encounter the combination of properties u and pv.
