Which of the following is an example of a model? PV=nRT, Geographical map, I believe that aliens exist, all of the above.
aleksandrvk [35]

<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.

Answer: The pressure of the He is 2.97 atm

Explanation:

According to Dalton's law, the total pressure is the sum of individual pressures.

p_{total}=p_{N_2}+p_{O_2}+p_{He}.

Given : p_{total} =total pressure of gases = 6.50 atm

p_{N_2} = partial pressure of Nitrogen = 1.23 atm

p_{O_2} = partial pressure of oxygen = 2.3 atm

p_{He} = partial pressure of Helium = ?

putting in the values we get:

6.50atm=1.23atm+2.3atm+p_{He}  

p_{He}=2.97atm

The pressure of the He is 2.97 atm
