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?

Explanation:

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 simple machine has three main features. they are:

fulcrum is the center point or pivot point of the machine. effort is input force/ applied force. load is external force/ output.

the keisha 's machine labels are

x : load

y: fulcrum

z: lever
