1.	Illustrate an activity along with a labelled diagram, to show that a change in the state of matter and change in temperature takes place during a chemical reaction.
Answer» Solution :Take about 5 g of quick lime in a beaker and add to it about 50 mL of water. A brisk REACTION takes place and a lot of HEAT is EVOLVED. `CaO+H_(2)O to CA(OH)_(2)+"Heat"` Quick lime is a solid but after the reaction, calcium HYDROXIDE is formed which is soluble in water and a clear solution is obtained. Thus, there has been a change in the state of matter and change in temperature.
