<u>Answer:</u> The correct answer is geographical map.
<u>Explanation:</u>
Model is defined as the three dimensional representation of a proposed structure in a smaller scale.
For the given options:
<u>Option 1:</u> PV = nRT
This is a proposed law. This law is known as ideal gas law. A law is defined as the rule which defined a correct procedure. For any gas behaving ideally, this law is used.
<u>Option 2:</u> Geographical map
Map is defined as the diagrammatic representation of an area of land or sea which also shows physical features, roads, cities etc..
A 3-D model can be prepared for geographical map.
<u>Option 3:</u> I believe that aliens exist
This is a hypothetical statement. It is a smart guess by the means of set of assumptions and observations. For its validation, we need to conduct some experiments.
Hence, the correct answer is geographical map.
At STP one mol weighs 22.4L
Moles of O_2
1 mol.O_2 can create 2mol water
moles of water
Volume of water
The internal energy of the ideal gas is zero
The change in internal energy for an isothermal process is zero.
An ideal gas has no interactions between particles, therefore no intermolecular forces.
pressure change at constant temperature does not change the internal energy.
Adiabatic throttling expansion has less work done and lower heat flow.
That lower the internal energy.
The temperature decreases during the adiabatic expansion
Hence the internal energy of the ideal gas is zero
