w=pg.
It means w is directly proportional to gravity. Hence w will not vary anywhere on the earth as gravitational acceleration is assumed more or less constant all over the earth
But this force of gravity varies on other planets hence sp.wt will change too.
Here 'other places' refers to places including earth and universe.
Answer must be B and C.

Specific weight is the weight per unit volume of a substance. Since weight depends on the gravitational acceleration, which varies slightly from place to place on Earth the specific weight of a liquid also varies accordingly. So both options B and C are correct.

I think the answer should be B and C because the value of g change from place to place even on earth so it does not remain contact at every place. And specific weight depends upon g and mass So it will change from place to place.

Specific weight is directly proportional to the weight of the fluid, means mass x gravitational force. And g is not constant at every place.
So, the answer should be C.
So, the answer should be C.

Specific weight is weight divided by volume, as weight depends upon mass and acceleration due to gravity and gravity changes place to place. So the answer should be C.

Option D is correct because Mass is constant but g changes. As g present nominators and denominators which cancel each other and remain constant.

Specific wt= wt/Vol & weight = mg and value of g varies for e.g in the moon it is 1/6th of the value of g. So The specific weight varies.

It should be B, as the acc Due to gravity changes from place to place even on our earth, so the Specific weight Also changes in accordance.

So at= wt. /vol, with an increase in temperature Specific weight Decrease because Temp increase, vol. Of fluid increase.

B and C both correct.
Because Sp.Wt =density (multiply) acceleration. Acceleration is variable place to place.
Because Sp.Wt =density (multiply) acceleration. Acceleration is variable place to place.
