Question

Boyle's law is represented by the equation PV=K (K is not constant), K depends on

• A. pressure of the gas
• B. volume of the gas
• C. mass of the gas
• D. all the above

Answer 1

Answer: (C)

mass of the gas

Answer 2

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
