Answer 2

Explanation:

i) = true ,

Yes, pure water can reflect light because water is the same in colour – colourless whether it is in any state (solid = ice, liquid = water, gas = vapour). Water can even transmit light.

ii) = true,

it is heavier than water, i.e, it's density is more than that of water.

iii) = true.

(iv)= true.

(vi) = true
