When 25 cm³ of 1.0 mol/dm³ hydrochloric acid is mixed with 25 cm³ of 1.0 mol/dm³ sodium hydroxide, the temperature of the solution increases by 3.0 °C.
What will be the temperature change when 25 cm³ of 2.0 mol/dm³ hydrochloric acid is mixed with 25 cm³ of 2.0 mol/dm³ sodium hydroxide, assuming no heat loss?
