hey kavya,
If you weigh an "empty" compressed gas cylinder and fill it with high pressure gas, it will then weigh more on an ordinary scale since you are weighing the gas in the cylinder. This will be demonstrated with a single molecule moving vertically, but the same result is obtained with any number of molecules moving in random directions so long as the collisions between them are elastic collisions. By giving the newtons law and evidence of Avogadro’s Theory.

We can measure the pressure, volume and temperature of gases and hence calculate the number of moles of gas...
hence we can know the mass of gas present......

. Because of the rotation of the earth, a plumb bob may not hang exactly along the direction of
the earth’s gravitational pull (its weight) but deviates slightly from this direction. Calculate the
deviation (a) at 40 latitude, (b) at the poles, and (c) at the equator

The length of a massless rod is measured using vernier callipers having 10 vernier scale divisions and least count of 0.1 mm. Two masses 1.00 ± 0.01 kg and 4.00 ± 0.02 kg are attached to its ends. If reading of vernier scale is 5 divisions coinciding with 1.3 cm, what is the % error in locating centre of mass from lighter mass
