Anita observed that coffee powder dissolves faster than
coffee granules in hot water. She remembered that the smaller
the particle size, the faster the reaction will be.
13. What was the initial observation of Anita?
Both coffee powder and coffee granules were dissolved at the same time.
b. Coffee powder dissolves faster than coffee granules in cold water.
Coffee granules have bigger particle size
d. Coffee powder dissolves faster in hot water than coffee granules.
14. What are the two variables that affect the fast dissolution of coffee?
a. Effect of Particle size
b. Effect of Temperature
c. Effect of Particle size and Temperature
d. Amount of Coffee

Answer:
13.D.
14.C.
Explanation:
13.Because coffee powder are smaller than the coffee granules,and it also base in the temperature,(hot water) when heat is applied,the faster the component will dissolve.
14.Like I said in number 13,it is because of the particle size and the temperature.
