If you push down the plunger of a bicycle pump the vhamber's volume is decreased. When that happens pressure in the chamber increases and the air then rushes out the pump and into your flat tire. What gas law does this represent?

Boyle's Law

Explanation:

Robert Boyle in his experiment explained the relationship between the volume and the pressure of a gas. In his experiments, he discovered that the volume of a gas is inversely proportional to the pressure at constant temperature. This implies that as the volume of the gas increase, the pressure decreases and as the volume of the gas decrease, the pressure will increase.

Now applying this concenpt to the the plunger of a bicycle pump, you will discover that as the pressure of in the plunger increase, the volume of air inside the chamber is decreasing as it is send out to pump the flat tyre. This clearly indicates inverse proportionality between pressure and volume as explained by Boyle's law.

Therefore, the plunger of a bicycle pump clearly indicates Boyle's law in action.

if the thermos has a vacuum innner, then heat through conv currents and conduction are reduced = vacuum flask

depends on what you mean by "group." for order, it would be coleoptera (beetles). for class, it would be insecta (insects). for phylum, it would be the arthropoda (animals with jointed exoskeletons).
