In the lab "Pressure in a Jar" what happened to the water when we squeezed the plastic jar.

• The air pressure in the container increased and the water in the glass tube went down

• The temperature increased and caused the water level to go up

• the pressure inside the glass bottle decreased and the water level got pulled down

If air has mass why does it not crush an empty cup?

• A cup pushes back against the air more then the air pushes

• Air pressure is the same inside and outside the cup

What is true about Boyle's Law?

• As volume decreases, pressure decreases

• Volume and pressure always stay the same

• As pressure increases, temperature decreases

• As volume increases, pressure decreases

• cloudy with precipitation

• sunny with high winds

• sunny, cool, and clear
