Mass, volume and density: Mass of freshtomatoes was determined using high accuracyelectronic balance. As the tomatoes were numberedthe weight of individual tomatoes were recordedevery day. The volume of tomato was determinedindividually by water displacement method usinga cylinder of 1 liter capacity. The mass and volumewere expressed in ‘g’ and ‘ml’ respectively (1ml=1cm3). Densities for tomatoes were calculatedusing the following equation:
