In which process will the internal energy of the system NOT change? a. An adiabatic expansion of an ideal gas.
marusya05 [52]

Answer:

B. An isothermal compression of an ideal gas.

Explanation:

The internal energy of an ideal gas is just function of the temperature; it does not matter what other thermodynamic property changes, if the temperature does not change, the internal energy neither does. That is just for ideal gases; real gases behaviour is not like that. All of the other options bring with them an increase or decrease of the temperature:

For A, the temperature will decrease because the gas will do work as it expands, converting part of his internal energy to work.

For C, the temperature will increase, because given PV=nRT, if the volume increases (expansion) and the pressure is constant, the temperature must increase to satisfy the equation.

Why is the pressure so high deep inside the outer planets?
AveGali [126]

Answer:

Due to its larger size

Explanation:

This is due to those planets being much larger than Earth. The larger a planet is, the more gravity that planet has, since gravity is mainly calculated based on the mass and radius of the planet. Also since the pressure deep inside of the planet depends mainly on the gravity of that planet on the surface, this is calculated as the square of the planet's surface gravity. Ultimately, the bigger the planet is the higher the pressure deep inside the planet will be.

D

Although water makes up a large portion of our earth, only a tiny fraction is drinkable. That is why we must protect it because if it becomes to dirty to purify, it could lead to not enough drinking water for us

PIT_PIT [208]
Because air and water have different density.
Air is less dense than water.
So, the light will bend towards normal.
Thus, the angle of refraction is smaller than angle of incidence.
This phenomena is known as refraction.
