Answer:
A sample of a gas (5.0 mol) at 1.0 atm is expanded at constant temperature from 10 L to 15 L. The final pressure is 0.67 atm.
Step by Step Explanation?
Boyle's law states that in constant temperature the variation volume of gas is inversely proportional to the applied pressure.
The formula is,
P₁ x V₁ = P₂ × V₂
Where,
P₁ is initial pressure = 1 atm
P2 is final pressure = ? (Not Known)
V₁ is initial volume = 10 L
V₂ is final volume = 15 L
Now put the values in the formula,
\begin{gathered}\rm 1\times 10 = P_2\times 15\\\\\rm P_2 = \frac{10}{15\\} \\\\\rm P_2 = 0.67\end{gathered]
Therefore, the answer is 0.67 atm.

Answer:
liquid
Explanation:
There are three states of matter and these are the following:
<em>1. Solid</em>
<em>2. Liquid</em>
<em>3. Gas</em>
"Liquid" has particles that show movements<u><em> in-between to that of the solid and liquid.</em></u> The forces between these particles are<em> weaker</em> when compared to the forces of particles in solid. This allows it to take the shape and volume of the container <em>without actually changing its volume.</em> If you pour a liquid unto a heart-shape container, it will take the shape of the heart as its form (it has no fix shape).
