Explain why the law of conservation of energy can mean that we do not have unlimited sources of energy.

1 answer:

5 0

<span>The law of conservation of energy states that energy can neither be created nor destroyed - it can only be converted from one form to another. It basically means that energy can't just appear, but has to be converted from existing energy; for example, the chemical energy in petrol is turned into electrical energy to power a car.Remember the total energy of universe is constant,,and no more energy can be drawn from out if we collect all universe's energy at a single point(its the big bang energy splitted during </span>

Answer:

Latent heat of fusion of the substance is $6.49\times 10^{4}J/kg$

Explanation:

Latent heat of fusion denotes amount of energy (heat) per unit mass required to melt a solid material at constant temperature and pressure i.e. at it's melting point

Here amount of heat required = $1.20\times 10^{6}J$

Mass of unknown substance being melted = 18.5 kg

So, latent heat of fusion of the substance = (required heat energy to melt)/(mass of the unknown substance) = $\frac{1.20\times 10^{6}}{18.5}J/kg=6.49\times 10^{4}J/kg$

So, latent heat of fusion of the substance is $6.49\times 10^{4}J/kg$
