Question

The gas pressure in a chamber varies
directly with the temperature in the
chamber. If the pressure in the chamber
is 150 atmospheres (atm) when the
chamber is at 50 degrees, what is the
pressure in the chamber when the
temperature of the chamber is 75
degrees?

Answer 1

Answer:

P=225 atm

Step-by-step explanation:

P is directly proportional to T

Converting Proptionality to equality we put a constant also

So

P=kT. (1)

Given P=150, T=50

Putting in (1)

150=k(50)

k=150/50

k=3

Now

P=? When T=75

Putting T and k in (1)

P=3(75)

P=225 atm
