Question 5

Question

What is pressure in relation to a gas?

a
the force the gas is exerting on its container
b
the force an object exerts on a gas
c
the amount of particles bumping into each other

Answer 1

The correct answer is:

a the force the gas is exerting on its container.

Pressure in a gas is defined as the force that the gas exerts per unit area on the walls of its container. This force results from the collisions of gas particles with the surfaces of the container.

Answer 2

Question 6
When refering to a gas, the higher the temperature, the faster the particles move

True
False

Answer 3

True

When referring to a gas, higher temperatures provide more energy to the particles, causing them to move faster. This increase in kinetic energy results in an increase in the speed at which the gas particles move.

Answer 4

Question 7
Volume refers to

a
the size of the gas
b
the size of the container
c
the amount of liquid that fits inside a container

Answer 5

The correct answer is:

b the size of the container.

In the context of gases, volume refers to the space that the gas occupies, which is determined by the size of the container in which the gas is held.

Answer 6

Question 8
If pressure of a gas goes up, the volume has to go down

True
False

Answer 7

True

According to Boyle's Law, if the pressure of a gas increases, the volume must decrease, provided the temperature remains constant. This inverse relationship means that as one variable goes up, the other goes down.
