Question

Which of the following is the mathematical representation of Gay-Lussac's law?
(Points : 3)
P1V1 = V2/T2

P1/T1 = P2/T2

V1/T1 = V2/T2

P1V1 = P2V2

Answer 1

@Somy


I chose B

Answer 2

you are right :3

Answer 3

Thank you! ^_^

Answer 4

A student increases the temperature of a 300 cm3 balloon from 30°C to 60°C. What will the new volume of the balloon be? (Remember to be careful with the units.)
(Points : 3)
273 cm3

300 cm3

600 cm3

329 cm3

Answer 5

which formula would you use for this? you have volume and temperature

Answer 6

i have no clue

Answer 7

okay remember this formula also :
Charles Law
\[\sf \frac{ V_1 }{ T_1 } = \frac{ V_2 }{ T_2 }\]

Answer 8

you are given
V1
T1
T2
you have to find V2

units for this formula are:
V = m3
T = Kelvin

Answer 9

so whats v1 t` and t2?

Answer 10

V 1
is initial volume
T1 is initial temperature

Answer 11

V2 is final volume and T2 is final temperature

Answer 12

Okay so I would have to do the fishtail division we learned in third frade for this?

Answer 13

grade**

Answer 14

I always choose the safe zone when it comes to units
which is why i told you to use the SI unit system

so first convert the units to ones i told you
and then calculate using that formula
& yes do this 3rd grade calculation AFTER converting to appropriate units

Answer 15

your final answer for volume will be in m3
so convert it to cm3 to match one of the options

Answer 16

i am so so confused

Answer 17

is it C?

Answer 18

Confused? lol u said grade 3 calculation :P
okay look
T is given to you in Celsius
and to convert it to Kelvin
all you need to do is add 273 to Celsius value

Answer 19

1cm3 = 1.0 × 10-6 m3
300cm3 = X? m3
X= 300 × ( 1.0 × 10-6)
so find it

Answer 20

once you find it
\[\sf \frac{ V_1 }{ T_1 } = \frac{ V_2 }{ T_2 }\]
you need V2 so rearrange the formula
\[V_2 = \frac{ V_1 \times T_2 }{ T_1 }\]

Answer 21

try solving now

Answer 22

ITS STILL CONFUSING. SO VERY CONFUSING. I dont get it. =.=

Answer 23

okay, which part you dont get?

Answer 24

From the very beginning to the very end

Answer 25

do you get the formula?

Answer 26

What I get is I have to plug things in to get the answer. thats it

Answer 27

so you dont get the units conversion

Answer 28

okay
i'll make it easy for you since you dont get units

forget about unit of volume
leave it as cm3
only change the temp
30°C +237 = 303 K = T1
60°C +273 = 333 K = T2
V1 = 300 cm3

use the formula
do grade 3 calculation
\[\sf V_2 = \frac{ V_1 \times T_2 }{ T_1 }\]

\[\sf V_2 = \frac{ 300 \times 333 }{ 303 }\]

Answer 29

does it make sense now?

Answer 30

sorry the internet blew out

Answer 31

its okay, more importantly, did you get it?
