1. Which of these physical situations describes an inversely proportional relationship?
(Points : 1)
The volume always decreases as the pressure increases.
The volume always increases as the pressure increases.
The pressure vs. volume graph is a straight line passing through the y-axis above the origin.
The pressure vs. volume graph is a straight line passing through the origin.
2. Which of these would illustrate that volume is directly proportional to time in an experiment?
(Points : 1)
The volume always decreases as the time increases.
The volume vs. time graph is a curved line rising to the right.
The volume vs. time graph is an S-shaped line rising to the left.
The volume vs. time graph is a straight line rising to the right.
A D
A and D are correct..just took quiz
1. The correct answer is: The volume always decreases as the pressure increases.
2. The correct answer is: The volume vs. time graph is a straight line rising to the right.
1. The correct answer is: The volume always decreases as the pressure increases.
To determine which physical situation describes an inversely proportional relationship, we need to look for a situation where an increase in one variable results in a decrease in the other variable. In the given options, the only situation that fits this description is when the volume always decreases as the pressure increases. This indicates an inverse relationship between volume and pressure.
2. The correct answer is: The volume vs. time graph is a straight line rising to the right.
To determine which situation illustrates that volume is directly proportional to time, we need to look for a situation where an increase in one variable results in an increase in the other variable. In the given options, the only situation that fits this description is when the volume vs. time graph is a straight line rising to the right. This indicates a direct relationship between volume and time, where an increase in time results in an increase in volume.
