a gas exerts less pressure when it has a a. smaller volume b. lower temperature c. higher temperature d. two of the above
1 answer:
The combined gas law is
with 1 and 2 both being anything with pressure, volume, and temperature. Since pressure is on the top and temperature is on the bottom, they are inversely related, meaning that when the temperature gets high the pressure goes low. In addition, since pressure and volume are both on the top, when volume goes down pressure goes down too. Therefore, since A and C are right, D is the correct answer

Answer:
Wave A.
Explanation:
The energy of a wave is directly proportional to the square of the amplitude.
If a wave has higher amplitude, it will have more energy. On the other hand, a wave having lower amplitude, it will have less eenergy.
In this case, we need to tell which wave has higher energy. Hence, the correct option is A because it has a higher amplitude.
Answer:
Explanation:
For this problem, we can use Boyle's law, which states that for a gas at constant temperature, the product between pressure and volume remains constant:
which can also be rewritten as
In our case, we have:
is the initial pressure
is the initial volume
is the final pressure
Solving for V2, we find the final volume:
