Answer:
The correct answer is A. less
Step-by-step explanation:
The text states that density is related to temperature, specifically mentioning that hotter gases tend to be less dense compared to colder gases. Option A matches this, stating that hotter gases are "less dense".
The other options are incorrect:
B. equally - Hot gases are not equally as dense as cold gases.
C. more - Hot gases are less dense, not more dense.
D. inversely - The relationship is not inversely proportional. As temperature increases, density decreases, but they are not in an exact inverse proportion.
Therefore, the answer is A: hotter gases tend to be less dense compared to colder gases.
