The molecules in a hot material are moving at a faster speed than the molecules in a cold material.

Due to its lower density, warmer air is under less pressure than cooler air.

A/An hygrometer is a tool that measures humidity levels in the air.

Near Earth's surface, wind speeds tend to be slower due to friction.

When air reaches its saturation, it can't hold any more water.

1.faster (or greater)

2.less

3.hygrometer

4.friction

5.saturation point

6.Wind is created from the sun heating up some parts of the earth faster than other parts. This then creates masses of warm and cold air. Low pressure air is warmer than cold pressure air. This rotates cold air into areas of low pressure and warm air rising to areas of high pressure.

Explanation:

the answer is; comparing the frequency of collisions with and without the device

this makes the anti-collision system an independent variable and the collisions a dependent variable. if there are fewer collisions with an anti-collision system that without, then it can be stated that the system is a success. essentially, collisions under an anti-collision system are compared with the frequency of collisions by cars with the human drivers.
