TRUE OR FALSE
Directions. Write True if the statement is correct and False if it is not.
1. A gas consist of very small particles, each of which has a mass.
2. The distances separating gas particles are relatively large
3. Gas particles are in constant, rapid, and random motion.
4. Collisions of gas particles with each other or with the walls of the container are perfectly elastic
5. The average kinetic energy of gas particles depends only on the temperature of the gas. Gases have higher
kinetic energy at a higher temperature and lower kinetic energy at a lower temperature.
6. Gas particles exert a force on one another, in other words, the attractive forces between gas particles are so
weak that the model assumes them to be zero.
7. The force of attraction between gas molecules is almost negligible.
8. Carbohydrates are also known as hydrates of carbon.
9. Monosaccharides are composed of one sugar.
10. Starch is the most abundant polysaccharide.
11. Sugar units of Polysaccharides are linked together by an ionic bond.
12. Dehydration synthesis results in breaking down large molecule of sugar to form single unit of
sugar.
lactose.
13. Galactose and glucose when undergo hydrolysis reaction, forms
14. Glucose can be readily absorbed by cell without undergoing any reactions.
15. Carbohydrates are sugars.​
