4) Activity 5: Check for Understanding (30 mins) A. True or False. Draw a check () mark in the given space if the statement is CORRECT and an (X) mark if the statement is INCORRECT. 1. Solid has a definite shape and indefinite volume. 2. BEC is a hot gas with negative and positive particles moving at a high speed. 3. Gas particles are moving randomly hence making it more expandable. 4. Oxygen is an example of a gas and at the same time element. 5. Malleability is an example of an extensive property. 6. Freezing water to become an ice is an example of physical change. 7. Cooking of egg is a physical change because it will only change its appearance. 8. Chemical change is usually irreversible. 9. Color alone is a physical property. But once a substance changes its color, it may indicate that it has undergone chemical change. 10. Volume is an intensive property.
