30ml of 0.10 \(Ba(OH)_2\) (aq) is added to 30 mL of 0.10 M \(H_2SO_4\) (aq) and the solution is stirred quickly. The rise in temperature, \(\Delta T_1\), is measured. The experiment is repeated using 90 mL of each solution and the rise in temperature, \(\Delta T_2\), is measured. What is the relationship between \(\Delta T_1\) and \(\Delta T_2\)?
