If temperature is constant, the volume of a gas varies inversely as its pressure. The constant of proportionality for this variation is 3750.
Temperature is the degree of hotness or coldness of the object.
According to the ideal gas law, pV =nRT
where, p=pressure of gas, V =volume of gas, n=number of moles of element of gas, R=Universal Gas constant and T =temperature
When the temperature is constant,
PV =constant =k
k = 150x 25
k = 3750
Thus , the constant of proportionality is 3750.
