Question 61625
First, write the equation of proportionality:
{{{V = kT/P}}} Substitute the values given by the measuring device to solve for k, the proportionality constant.
{{{210 = k(280)/20}}} Solve for k.
{{{k = 20(210)/280}}}
{{{k = 15}}}
The proportionality equation is:
{{{V = 15T/P}}} Substitute the given values of T = 210 and P = 25
{{{V = 15(210)/25}}}
{{{V = 126}}}Cu.ins.
