*changeable shape and volume
*fixed shape and volume
*fixed shape, changeable volume

Answer 1

first one fixed volume and changeable shape because he change the amount of liquid you have but it will conform to any shape

Answer 2

you cant*

I can try :)

Answer 5

2. In a nitrogen gas occupies has a volume of 500ml at a pressure of 0.971atm.What volume will the gas occupy at a pressure of 1.50 atm, assuming the temperature remains constant?
A. 342mL
B. 424mL
C. 324mL
D. 442mL
E. 242mL

Answer 6

do u want me to show you how to do it?

Answer 7

yes please.

Answer 8

For the first one, you would use the formula PV=K which is Boyles law. You would multiply 500 ml X 0.971ATM, which would give you 485.5, now just use the formula.
P= 1.50 and V=? (since we don't know), and it equals K (which is the 485.5)
V X (1.50 ATM)= 485.5
Solve like algebra, 485.5/1.50 and that gives you 323.6 which you can round to 324ml

Answer 9

Thank you @heathred

Answer 10

Good explanations! @heathred

Answer 11

Can you help with the second one @heathred

Answer 12

For the next one, just do the same exact thing. PV=K, so you'd multiply the 5.0 ATM with the 40 L, and you'd get 200. So plug everything in (1.0ATM) X (V?)= 200L, divide both sides by 1 and you get 200L

Answer 15

I have to do my math homework but follow the formulas of boyles law, charles law, and gay-lusaccs law and you should be good. once im done i will come back on and if you still dont get it ask.

Answer 16

ok thank you for all your help
