Solid R reacted with dilute sulfuric acid.

The initial temperature of the dilute sulfuric acid and the final temperature of the solution are shown.

initial temperature of the dilute sulfuric acid $\left({ }^{\circ} \mathrm{C}\right)$

What was the change in temperature in ${ }^{\circ} \mathrm{C}$ ?

The diagrams show liquids in a burette and a measuring cylinder.

Which row shows the correct readings for the burette and the measuring cylinder?
