<h2>Explanation:</h2>When decreasing a volume while maintaining the same pressure, the temperature will have to decrease. When volume decreases, particles get squished, increasing pressure. But when temperature decreases, particles move slower, decreasing pressure. The lowered temperature decreases pressure, but the decreased volume increases pressure, so pressure is able to stay constant.
About the 3 main gas laws covered in Edge:
- Charles's law says that under a constant pressure, when temperature increases, the volume increases, and vice versa. The equation for this law is V₁/T₁=V₂/T₂.
- Gay-Lussac’s law says that under a constant volume, when temperature increases, the pressure increases, and vice versa. The equation for this law is P₁/T₁=P₂/T₂.
- Boyle’s law says that under a constant temperature, when volume decreases, pressure increases, and vice versa. The equation for this law is P₁V₁=P₂V₂.
Note that P=pressure, V=volume, and T=temperature. When given a problem, plug in the given values into the correct spots and solve for the unknown value.
