Question 6

Thermal energy vs temperature

Answer 6

Total kinetic energy vs. average kinetic energy

Question 7

What happens when there’s heat vs cold air againast watwrb

Answer 7

Heat breaks the hydrogen bonds and cold forms the hydrogen bonds

Question 8

Apply the knowledge of heat and cold weather affevtijg water and hydrogen bonds

Answer 8

In summer the air will be colder because the bonds are forming and in winter the air will be warmer because the bonds are forming

Question 9
