Matter is everything around us that has mass and occupies space. It exists in three main states: solid, liquid, and gas. The state of matter depends on temperature and pressure. Solids have a definite shape and volume, liquids have a definite volume but no fixed shape, and gases have neither. Matter can change from one state to another through processes like melting, freezing, evaporation, condensation, and sublimation. This Matter and Changes Around Us Quiz for Class 7 explores these physical transformations and the conditions that cause them. These changes are physical changes because they do not alter the chemical composition of the substance. Changes also occur in matter due to heating, cooling, mixing, or chemical reactions. Understanding matter and its changes helps students recognise physical and chemical changes in everyday life and the conditions under which they occur. Attempt these 10 multiple-choice questions to assess your knowledge of matter and changes.
