Frosh PhySci - Charles Law quiz

Question 0

F -

What is Charles’ law?

Answer 0

When pressure is held constant……
Increased heat—> increased volume
Decreased heat–> decreased volume

Question 1

F -

The amount of space that matter takes up is its ___________.

Answer 1

volume

Question 2

F -  
Heating a gas gives its particles
a- more energy
b- greater speed
c- a higher temperature
d- all of the above

Answer 2

D- all of the above

Question 3

Why did Charles and Guy-Lussac hold the pressure of gas constant in their investigations of volume and temperature?

Answer 3

They already knew that the pressure of a gas affects its volume.

Question 4

T/F A hot air balloon inflates because it is pumped full of helium.

Answer 4

False It is not just the gas (helium). Think deflating helium balloon. If volume is not large enough it will not float.

Question 5

What might happen to a latex balloon filled with air if you heat it up?

Answer 5

Air pressure will rise and volume increase (expands). It might expand enough to pop.

Question 6

F -  
If you heat gas in a closed container that cannot expand, the gas will increase in 
a- mass
b- volume
c- weight
d- pressure

Answer 6

d- pressure

Question 7

F -  
What type of relationship exists between the temperature and volume of a gas?
a- inverse relationship
b- direct relationship
c- reverse relationship
d- none of the above

Answer 7

B - direct relationship Heat increase–> volume increase

decrease decrease

Question 8

Charles and Guy-Lussac were influenced by the earlier gas research of _____________.

Answer 8

Robert Boyle

Question 9

T/F For a gas under constant pressure, volume and pressure increase together at a constant rate. Huh?????. Typo!!!

Answer 9

True
