Plants use carbon dioxide to make food.
Answer:
D) All of the above
Explanation:
When the temperature increases, it means that the kinetic energy of the gas molecules had increased too because the temperature is a way to measure this kinetic energy. When this happens, the velocity of gas molecules increases because kinetic energy and velocity are directed related:
Where <em>Ek</em> is the kinetic energy, <em>m</em> is the mass and <em>v</em> is the velocity.
If the velocity increases, there will be more collisions between molecules, so, with more collisions, the pressure, which is the measure of the force a gas makes in the system, will increase. So, all the answers explain why the pressure of a gas increases when the temperature increases.
When the speed of the particle is close to that of light, it's observed mass would be infinitely large.
To answer the question, we need to know what observed mass is.
<h3>What is observed mass in relativity?</h3>
This is the mass the body of an object in relativistic motion appears to have.
So, observed mass, m' = m/√(1 - β²) where
- m = rest mass and
- β = relative velocity of isotope to light.
Now, since the speed of the particle is close to that of light, β ≅ 1.
So, m' = m/√(1 - β²)
m' = m/√(1 - 1²)
m' = m/√(1 - 1)
m' = m/√0
m' = m/0
m' = ∞
So, when the speed of the particle is close to that of light, it's observed mass would be infinitely large.
