Will five litres of benzene weigh more in summer of winter ? Comment.

Explanation

Weight = mg = `(V_(rho))`g where `rho` is density. Now,
V and g are constant. Therefore weight `prop rho`
in summer, temerpature ries. Therefore, due to
v thermal expansion density `rho` decreases, and
hence, the weight decreases. Thus 5 litres of
benzene will weigh more in winter than in
summer.
