Q.
Boyle's law is represented by the equation PV=K (K is not constant), K depends on
Thermal Properties of Matter
Solution:
From idea gas equation, we know that $PV = nRT = K$ (given) Clearly, $K$ depends on $n$ ( = number of moles)
and number of moles $=\frac{\text { mass of gas given }}{\text { molecular mass of gas }}$
So, K depends on mass of gas
