Will give brainlist, points, stars, etc. can someone me reword this ? i don't like how i did it. photosynthesis turns carbon dioxide and water into oxygen and carbohydrates, therefore a chemical change happens. it is also an endothermic reaction because energy needs to be inputted in order for photosynthesis to occur. the energy input is then stored in the bonds of the glucose that were formed as a result of photosynthesis.

Photosynthesis turns sunlight, water and carbon dioxide into energy and oxygen. Clorophyll is also a result of this process. "Photosynthesis turns carbon dioxide and water into oxygen and carbohydrates, therefore a chemical change happens." (keep what you wrote there) "It is also an endothermic reaction because SOLAR energy needs to be inputted in order for photosynthesis to occur. The energy input is then stored in the bonds of the glucose that were formed in the plant as a result of photosynthesis."

False (1). Reference to, or calculation of, different densities leading to

different masses (1) (2 marks)

b True (1). Density of olive oil is less than water and sea water but greater

than that of alcohol (1) (2 marks)

c False (1). Gold has a greater density than aluminium so equal masses

for both mean that gold will have a volume that is much less than that

of aluminium (about 7

1 of that of aluminium) (1) (2 marks)

d True (1). Use of mass = density × volume for both leads to the same mass;

or a similar argument (1)
