Answer 1

1. Cohesion
2. Temperature moderation
3. Expansion when frozen
4. Versatile Solvent

Question 2

What are the two emergent properties of water important for transpiration in plants?

Answer 2

Cohesion (water sticking to itself) and Adhesion (water sticking to itself)

Question 3

What makes water good at moderating temperature?

Answer 3

its high specific heat (4.2J/gC) making it take more energy absorbed to warm up

Question 4

thermal energy vs. Temperature?

Answer 4

thermal energy takes into account the volume of water, temperature is regardless of volume

Question 5

What makes water a versatile solvent?

Answer 5

the hydration shell it forms around ions, making them less likely to bond with one another

Question 6

What is an acid on the pH scale?

Answer 6

below 7

Question 7

what is a base on the pH scale?

Answer 7

above 7

Question 8

What is a buffer and what must it be made of?

Answer 8

A reversible reaction that takes place to keep pH where it needs to be (must be made of WA and WB, as SA and SB can’t be reversible)
