Answer (1)
1. True. Molecules are formed when two or more atoms are joined together. This is the definition of a molecule. 2. True. The particles of a gas are hard to be controlled. Gas particles are widely spaced and move randomly, making them difficult to contain or direct. 3. False. A liquid takes the shape of its container, but it has a definite volume. Liquids conform to the shape of their container, unlike solids which have a definite shape. However, unlike gases, they maintain a constant volume.
