Test#1: term 2: Factors Influencing Pressure, sec 3

Question 1

Factors:

Answer 1

surface area
force
temperature
volume

Question 2

Surface Area:

Answer 2

the larger the surface area, the lower the pressure. The smaller the surface area, the higher the pressure.

Question 3

Force:

Answer 3

When the size of the surface area is the same, the pressure will be greater if the force applied is great. Therefore, the lesser the force, the lower the pressure.

Question 4

Temperature:

Answer 4

The higher the temperature of a gas, the faster particles are moving. Faster particles have more collisions between them, so the pressure increases. The lower the temperature of a gas, the slower the particles are moving. Slower moving particles have less collisions between them and therefore a lower pressure.

Question 5

Volume:

Answer 5

Gases do not have a defined volume. An increase in volume will result in a decrease in pressure since there is more space to move and therefore fewer collisions between the particles. A decrease in volume will result in an increase in pressure since there is less space for particles to move and more collisions between them.
