Hi there!
Gravity from the sun is even and makes a planet orbit the sun by exerting a force that pulls the planet towards it. Since the gravity of the sun is always the same (or very, very similar), the planet's orbit stays the same.
Hope this helps!
They provide a place for marine life to flourish, that would otherwise most-likely go extinct because of the constant decrease of natural reefs in our oceans.

Based on the fact that the question mentions a change in pressure and the aim is to determine the change in volume, then it is evident that the premise of the question is Boyle's law (Pressure increase when Volume decrease and vice versa when the temperature remains constant). Thus Boyle's Equation can be used to determine the answer.
Boyle's Equation: P₁V₁ = P₂V₂
Since the initial pressure (P₁) is 0.428 atm, the final pressure (P₂) is 0.724 atm, the initial volume is 240 mL, then we can substitute these into the equation to find the final volume (V₂).
P₁V₁ = P₂V₂
∴ by substituting the known values,
⇒ (0.428 atm) (240 mL) = (0.724 atm) (V₂)
⇒ V₂ =

⇒ V₂ =
141.88 mLThus the final volume of the sample is approx.
