It takes about 81 joules to melt one gram of gallium. During the melting, the temperature stays constant. Which has higher entropy, a gram of liquid gallium at 3° C or a gram of solid gallium at 3° C (276 K)? solid liquid How large is this difference in the entropy between the two forms of gallium?

Entropy is the measure of a thermodynamic system's thermal energy per unit temperature that is usually not available for doing useful work. It is also a measure of the degree of disorderliness or molecular randomness of a system.

a gram of gallium liquid has a higher entropy compared to a gram of solid gallium at 3 ° C for both of them because the liquid has more energy and the particles can translate compared to the solid form

change in entropy when temperature is constant = Q / T = 81 Joules / 276 K = 0.293 J/K

The entropy of a gram of liquid gallium at 3° C has a greater entropy than a gram of solid gallium at 3° C. At constant temperature, 0.29 J/K

Entropy refers to the degree of disorder in a system. The more ordered a system is, the lower the entropy of the system. Since a solid is more ordered than a liquid, a gram of liquid gallium at 3° C has a greater entropy than a gram of solid gallium at 3° C.

At constant temperature; the entropy of the system is;

Entropy = 81 joules/276 K = 0.29 J/K
