Give the required practical for temperature change.

1)Place polystyrene cup in glass beaker to make it more stable. 2)Measure an appropriate volume of each liquid, eg 25 cm3. 3)Place one of the liquids in a polystyrene cup. 4)Record the temp of the solution 5)Add the second solution and record highest or lowest temp obtained 6)Change your independent variable and repeat the experiment. (Your independent variable could be the concentration of one of the reactants, or the type of acid/alkali being used, or the type of metal/metal carbonate being used.)
