Answer: 318 K
Explanation:
Combined gas law is the combination of Boyle's law, Charles's law and Gay-Lussac's law.
The combined gas equation is,

where,
= initial pressure of gas = 231 kPa
= final pressure of gas = 168 kPa
= initial volume of gas = 3.25 L
= final volume of gas = 4.35 L
= initial temperature of gas = 
= final temperature of gas = ?
Now put all the given values in the above equation, we get:


At 318 K of temperature will the same gas take up 4.35 liters of space and have a pressure of 168 kPa
Wind, air that moves to the ground
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
Heavy rainfall causes a landslide. Hence, option A is correct.
<h3>What is a landslide?</h3>
A landslide is defined as the movement of a mass of rock, debris, or earth down a slope.
Water can trigger landslides and mudslides because it alters the pressure within the slope, which leads to slope instability.
Consequently, the heavy water-laden slope materials (soil, rock, etc.) will succumb to the forces of gravity.
Hence, option A is correct.
