Question

A given quantity of a liquid is heated.which of the following quantity will vary and how?(a)mass (b)volume and (c)density

Answer 1

Assuming no loss of quantity due to phenomenon such as evaporation, heating would keep the mass constant because mass is the amount of matter contained in a body/object/system. The volume and density would depend on the coefficient of volumetric thermal expansion.

If the coefficient, say ß is negative it implies that the volume decreases and density increases with rise in temperature. If ß is positive then the volume would increase and density would decrease.

Also a same liquid could show both these behaviors but at different temperatures.
