Frosh PhySci - Boyles Law Flashcards
(10 cards)
T/F Robert Boyle has been called the “father of modern chemistry”
True
F -
Boyle’s law relates the volume and ________ of gases.
pressure
Boyle’s methods of doing science were unusual for his time. Why?
Unlike others, Boyle did controlled experiments and provided detailed descriptions of his procedures and observations when he published his results.
The scientific method.
F -
Explain why gases exert pressure.
Their molecules are always moving and bouncing of each other and anything else in their path. When gas molecules bump into things, it creates pressure.
F -
The relationship between the pressure and volume of a gas is a(n) _______ relationship.
Inverse
F - For Boyle's law to apply to a gas, which variable must be held constant? a- volume b- pressure c- temperature d- None of the above
C- Temperature
Why does squeezing a fully inflated balloon cause it to pop?
Squeezing decreases the volume and increases the pressure. Inverse relationship. High enough pressure pops the balloon.
Explain why gas pressure is greater when gas molecules occupy a smaller space.
Molecules are more crowded together. Therefore more collisions and higher pressure.
Assume that you put the same amount of room-temperature air in two tires. If one tire is bigger than the other, how will air pressure in the two tires compare?
a- The bigger tire will have greater air pressure
b- The smaller tire will have greater air pressure
c- Both tires will have the same air pressure
d- Not enough information is provided to know the answer
B- smaller tire will have greater pressure
F -
T/F Boyle’s law applies to liquids as well as gases
False
