In most cases, what happens to a liquid when it cools?
a) its density increases
b) its density decreases
c) its mass increases
d) its mass decreases
e) its volume increases
f) its volume decreases

Option (A) and (F)

Explanation:

As the liquid cools down, it means the temperature decreases the density of the liquid increases in most o the cases.

Now the volume is inversely proportional to the density of substance so density increases.

okay i have so many questions. but the big one here is: um wt..f is this mess? ?

igneous rocks also form where plates converge. the subducting plate melts as it sinks into the crust of the earth, and the melt rises into the overriding plate forming volcanoes. metamorphic rocks are formed mainly in the lithosphere, wherever there is high pressure and high temperature. -woods
