Explanation:

During a chemical change, new substances are formed. Temperature change can occur due to heat absorption or release. Color change indicates formation of new substances with different optical - properties. Production of gas and light are also signs of chemical reactions as new substances are being formed with different energy states. Change in shape is a physical change, and melting, boiling, and evaporation are phase - change physical processes.

Answer:

temperature change, color change, production of gas, production of light
