A sample of Ar gas has a volume of 6.30 L with an unknown pressure. The gas has a volume of 8.57 L when the pressure is 2.74 atm
ExtremeBDS [4]

Answer:

3.73 atm

Explanation:

Since there is no change in temperature, we use Boyle's law.

P₁V₁ = P₂V₂ where P₁ = initial pressure of Ar gas = unknown, P₂ = final pressure of Ar gas = 2.74 atm, V₁ = initial volume of Ar gas = 6.30 L and V₂ = final volume of Ar gas = 8.57 L

P₁ = P₂V₂/V₁ = 2.74 atm × 8.57 L/6.30 L = 3.73 atm

How do you tell if the sample of matter is solid,liquid or gas?
soldi70 [24.7K]
There is one simple way to determine between solids, liquids, and gases. Are you able to move the substance? And if you are, how does it move? If it takes on the shape of its new container, it is a liquid. For example, if you pour water from a cup into a bowl, it will fill the bowl, not stay in the same shape as it was in the cup. However, if you put a marble in a cup and then pour the marble into the bowl, it will remain the same shape, and is therefore a solid. If you move a gas into a container, and the container is not sealed, it will not remain in the same shape.
