What is a solvent? The one doing the dissolving - The substance dissoved in another substance

Which container will have lower pressure? left - right - they both have the same pressure

If a hairspray can is heated, what can be expected of the pressure of the gas inside the can? The pressure will increase -The pressure will decrease

Cooling a plastic bottle in a freezer will ......................... the air particles inside. speed up - slow down

Pressure can be exerted by solids, liquids and gases. ? TRUE - FALSE

Diffusion occurs only in solids True- False

The net movement of particles from a region of high concentration to a region of lower concentration due to random movement is the definition of:

How can we increase the gas pressure inside a sealed container? Increase the number of particles inside the container- Increase the temperature -Decrease the volume of the container -All of these

At the top of a mountain, the air pressure will be ............................. low - high

In what direction(s) does air exert pressure? In all directions - In no direction -there is no pressure

What is a solute? A substance dissolved in another substance - the substance doing the dissolving

The reason gases can be compressed is because: ? The particles are very close together. - The particles are merely vibrating. - The particles are unable to move.- The particles are very far apart.
