Answer: The standard entropy of vaporization of ethanol is 0.275 J/K
Explanation:

Using Gibbs Helmholtz equation:

For a phase change, the reaction remains in equilibrium, thus 

Given: Temperature = 285.0 K

Putting the values in the equation:


Thus the standard entropy of vaporization of ethanol is 0.275 J/K
Solid , solid, partially melted, liquid so the answer is D
Answer:
50 N
Explanation:
Because It not in motion means it standing still. So the answer is 50 Newton
