Charles's law states that
a. the pressure of a gas is inversely proportional to its temperature in kelvins
b. the volume of a gas is directly proportional to its temperature in kelvins
c. the pressure of a gas is directly proportional to its temperature in kelvins
d. the volume of a gas is inversely proportional to its temperature in kelvins

B. The volume of a gas is directly proportional to its temperature in kelvins

Explanation:

As per ideal gas equation we know that

now if the pressure of ideal gas will remain constant and the moles of the gas is fixed then in that case we can rearrange the above equation

here since moles and pressure is always constant so for two different temperatures we will have

so here we can say that as per Charle's law

B. The volume of a gas is directly proportional to its temperature in kelvins

no. dot product   =0 when vecs at right angles
