Answer:
Thermal energy is transferred between particles that are in direct contact with each other.
Thermal energy is transferred between objects of different temperatures.
Thermal energy is transferred from fast-moving particles to slow-moving particles.
Explanation:
Liquefied Natural Gas
Explanation:
Gases are usually liquefied in the downstream sector during crude processing. These natural gases are products of distillation of crude oil in fractionating columns. Some of them are also found in geological formations.
- To easily transport these gases, they are liquefied in vessels that carries them from one place to another.
- Liquefaction is the process of converting a gas or solid into a liquid form.
- Gases are usually compressed under very high pressure into vessels through which can make them easier to transport.
- Gases do not have a fixed volume and they typically assume the volume of any container they are taken into.

Answer:
The molar amount of the gas.
Explanation:
If the pressure, volume, and temperature of a gas are known than molar amount can be determine.
Formula:
PV = nRT
P = pressure
V = volume
R = general gas constant
T = temperature
n = number of moles
Example:
V = 2 L, P = 1 atm , T = 273 K , R = 0.0821 atm. L/mol.K
n = PV/RT
n = 1 atm. 2 L / 0.0821 atm. L/mol.K . 273 K
n = 2 / 22.413 /mol
n = 0.09 mol

Answer:
b. 1.5 atm.
Explanation:
Hello!
In this case, since the undergoing chemical reaction suggests that two moles of A react with one moles of B to produce two moles of C, for the final pressure we can write:
Now, if we introduce the stoichiometry, and the change in the pressure 
we can write:
Nevertheless, since the reaction goes to completion, all A is consumed and there is a leftover of B, and that consumed A is:
Thus, the final pressure is:
Therefore the answer is b. 1.5 atm.
Best regards!
