11.8 absolute temp and charles law.

Question 1

what is the kelvin scale

Answer 1

a scale that is always pos (measures temperation)
–> why to ensure that you will never have negative pressure
(pressure and temp have a proportional relationship according to the gay lussex law)

Question 2

if you have double the kevin does the pressure double?

Answer 2

yes because kelvin is an absolute scale, whereas when you double the temp the pressure is not doubled

doubling the kelvin = doubling the kinetic energy

Question 3

what is absolute 0

Answer 3

-273.15 degrees celcius (which is 0 kelvin)

Question 4

true or false. 1 k = 1 degrees c

Answer 4

true (kevin and ceclius has the same size unit division)

Question 5

what is charles law?

Answer 5

temeprature and volumn are proprtional. as you heat a gas up the vilumn gets bigger

pressure and amount of mole (n) must remain constant

v1/t1 = v2/t2

Question 6

what graph shows the charles law (axies)

Answer 6

volumn x temp graph (straight line slop, and data was extrapolated to get the absolute 0 temp)

Question 7

how does charles law work at a molecular level?

Answer 7

temp increase = increase of kinetic energy

more inetic energy results in more collisions betweedn the entities and the walls of the container, therefore the container expands, resulting in more volumn.

Question 8

what is aboslute temp?

Answer 8

the measurement of average kinetic energy of entities in a substance (unit symbol K)

Question 9

what is the kelvin temperature scale?

Answer 9

a temperature scale that includes absolute 0 and same size unit divisions as the celsius temp scale
