The pressure exerted on the walls of a container by a gas enclosed within it is directly proportional to the temperature of the
Inessa [10]

Answer:

Step-by-step explanation:

If y is directly proportional to x, then the formula for that is a linear one:

y = kx, where k is the constant of proportionality.  In our situation, if the pressure is directly proportional to the temp, then our formula is

P = kT.  We need to find that value of k.  Plug in what we have:

6 = k(440) so

k = .01363636 or as an equivalent fraction,

k=\frac{3}{220}

Now that have that value of k, we can use it in the formula again, this time with a different value for T to solve for P.

P=(\frac{3}{220})380 so

P = 5.181818 or as an equivalent fraction,

P=\frac{513}{100}
