Question

use gay-lussac's pressure law to explain what happens to the temperature, pressure and volume of the air inside refrigerators and freezers. explain at a molecular level

Answer 1

Medals 1

P(1)V(1)/T(1)=P(2)V(2)/T(2)
use the followings equations to find out ur answer...

Answer 2

is there anyone one that can give me a nice big paragraph of a answer, this is distinction work

Answer 3

which bit

Answer 4

the aloft-lussac s law is the following one which i v written but there is another one which can be used in the molecular level :
\[PV=nRT\]
the n is the amount of mole
the R is a global constant
R=287.05 \[J/kg.K\]

and the T is the temperature(Kelvin)

Answer 6

esmail, I also gave you the outline of an answer a few days ago, with a diagram and the steps of refrigeration.

Answer 7

no,no,no i said use the ideal gas law, this is "uses gay-lussac's law"

Answer 8

i dont get it? ?help

Answer 9

What is the Aloft-Lussac Law? This isn't a standard name for a gas law. But in any case, I'll bet a nickel it is special case of the ideal gas law.

Tell us exactly what it is.

Answer 10

the admin got rid of the name " g ... a ... y "

Answer 11

its not aloft its " g.............a.........................y" admin took it off

Answer 12

It's this then:
http://en.wikipedia.org/wiki/Gay-Lussac's_law#Pressure-temperature_law

This is a special case of the ideal gas law. It says pressure is proportional to temperature.

So everything I have said above and Deuter said above applies.

Answer 13

[btw, I think it's inane that this site blocks g a y ]

Answer 14

again, fix that link: replace aloft with g a y

Answer 15

can you just give me an answer to the question please
im doing BTEC so i need a full answer ....

Answer 16

this should work

Answer 17

imran can u help me answer the question

Answer 18

"The pressure of a gas of fixed mass and fixed volume is directly proportional to the gas' absolute temperature."

let start from obvious .

We know that temperature drop in refigerators and freezer , according to law above , pressure should drop too. and I think volume remain the same

Answer 19

thanks
