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 $6.49\times 10^{4}J/kg$

what property easily changes in gases but does not easily change in solids a.mass b.color c.shape d.smell

liq [111]

C. Shape, because increasing pressure has a profound influence on the volume of a gas sample, for example, it pushes the particles closer together; thus gases are considered compressible.
