this is bcos,they get constantly subjected to friction,pressure,temperature which has drastic effect on their size and shape and after a long period of time their properties get changed.
The oxygen in the air eats away all the particles in the wax and without all the particles it shrinks.
You don't say which speed, but all change over time.
The particles change mean speed and concentration.
False. Acceleration is a change of speed or direction over time.
The answer is displacement.
The oil filter is there to trap any tiny particles that are in the oil. You change it because it becomes dirty over time. Change the oil at every oil change.
You think probable to radioactive decay.
A volcano. Because it can emit enough dust and airborne particles to cast a cooling shadow over the earth for some time.
How have valleys change over time?How have valleys change over time?How have valleys change over time?
How did the dirction of the moon change over time? How did the dirction of the moon change over time?
It starts with the weathering of exposed igneous rock into smaller particles over a long long period of time.
A change over time is often referred to as a gradual change.
Suspension
dispersed phase.
Yes, friends do and will change over time. Every person changes over time.
Because over time it can trap small particles and become partially clogged. This puts a strain on the fuel pump and can shorten it's life.
