Haw does density of a liquid vary with the temperature

as temperature cools density increases

Explanation:

Density is the ratio of mass to volume. When the temperature varies, the volume of the liquid changes. ... Also, cooling a substance causes molecules to slow down and get slightly closer together, occupying a smaller volume that results in an increase in density.

i think the answer is a and b

i wish you luck

distance = 150m

displ = root (50 ^2 + 100^2)

root(2500+10000)

root 125000
