in air filled baloon , we can say that there is a specific volume of air , then can we say that air has volume ??also the difference between the mass of a baloon and the mass of a air filled ballon indicates that air has some mass right ????
Yes Harini exactly, air has volume as well as mass. But air does not have fixed volume , it varies depending upon the size of container. Bigger the container,more the volume and smaller the container lesser the volume.
