Question

what is gay lussac law

Answer 1

Gay-Lussac's Law gives the relationship between pressure and temperature when volume and amount are held constant. In words:

1) If the temperature of a container is increased, the pressure increases.
2) If the temperature of a container is decreased, the pressure decreases.
The mathematical form of Gay-Lussac's Law is:

P
––– = k
T
This means that the pressure-temperature fraction will always be the same value if the volume and amount remain constant.

Let P1 and T1 be a pressure-temperature pair of data at the start of an experiment. If the temperature is changed to a new value called T2, then the pressure will change to P2.

P1
––– = k and
T 1

P2
––– = k
T 2

since k =k
we get , P1/T1 =P2/T2
