Viscosity and the effects of Temperature 3

Question 1

How does temperature affect the viscosity of a gas?

Answer 1

When heat is applied to the gas, the particles move faster, creating greater resistance(friction). As the temperature decreases the particles slow down and collide less often, so there is less friction.

Question 2

How does temperature affect the viscosity of a liquid?

Answer 2

As the temperature of a liquid increases, its viscosity decreases and the fluid flows more easily. The warmer the liquid, the faster it flows.
As the temperature of a liquid decreases, the particles slow down. In result the viscosity increases. The cooler the liquid, the slower it flows

Question 3

Reasons why a substance float in some fluids, but sink in others:

Answer 3

1. If the density of a substance is greater than the density of the fluid, the substance will SINK.
2. If the density of a substance is less than the density of the fluid, the substance will FLOAT.
3. If the density of a substance is the very same as the density of the fluid, the substance will “HOVER” in place.
