20. Hannah was conducting an experiment that had her add 5g of a metal to a beaker of cold water Dunne
she repeated the same experiment with hot water, she noticed the gas bubbles were released much more reply
А.
Hot water increases the collision rate of the molecules, causing the reaction to occur faster
B.
Hot water increases the surface area of the molecules, causing the reaction to occur taster
C
During the second experiment a chemical change occurred, whereas the first experiment resulted in a physical change
D. The temperature of the water does not effect the speed of the reaction, as there are other variables that could impact the speed of the reaction
