To determine the heat of neutralisation, Chelsea placed 50 cm' of sodium hydroxide solution of concentration 1.0 mol dm- in a polystyrene cup and recorded its
temperature. She then recorded the temperature of 50 cm of sulfuric acid, added it
to the cup, stirred the solution and recorded its maximum temperature, as follows:
. initial temperature of NaOH(aq) = 29.5 °C
. initial temperature of H.SO, (aq) = 29.9 °C
• maximum temperature of the solution = 35.8 °C

Calculate the increase in temperature

The process that breaks down rock through chemical changes. Weathering in which solid rock is fragmented by mechanical processes that do not change its chemical composition. Process that splits rock when water seeps into cracks, then freezes and expands. Weathering is the force that breaks down rocks.
