A reaction occurs when solid X is placed into solution Y. As a result, the temperature of the new solution increases by 3°C. The temperature rises another 2°C when more of solid X is added to the solution. What does this indicate about the effect of adding more solid?
It increased the number of molecular collisions.
It decreased the number of molecular collisions.
It decreased the space between the molecules and lowered the reaction rate.
It increased the space between the molecules and increased the reaction rate.

It increased the number of molecular collisions.

Explanation

If the temperature increased after the solid was added, this indicates a reaction, reactions are molecules colliding.

it increased the space between the molecules and increased the reaction rate

Explanation:

when molecules start to heat up they begin to spread apart from each over causing a heating reaction hope this helps

the mantle

explanation:

earth is divided into three layers: the crust or the outermost layer on which we live; the underlying, middle layer - the mantle - and the core (the innermost layer of earth).
