A STUDENT HAVE 5 LITRES OF BENZENE.AND HE MEASURED ITS WEIGHT DURING SUMMER AND WINTER DAYS......SO,DURING WHICH SEASON ,HE WILL OBSERVE MORE WEIGHT.

• I agree with Prateek and lakshmi if you are comparing weight of 5 litres benzene in different temperatures.
  
  But if u r asking for same 5 litres of benzene in a closed container in different temperatures, then weight will not change ( ignoring any loss in quantity )..... as the student has 5 litres of benzene only.

• Weight will be higher in winter as compared to summer..................Because concentration of weight is higher during winter season in Benzene...............
