Describe the temperature change practical.

1)Mesure out 30cm3 dilute hydrochloric acid transfer to pelestyrene cup and place it in beaker 2)Mesure temp of acid with themometer 3)Mesure 5cm3 sodium hydroxide and transfer to cup 4)Add plastic lid with hole and place thermometer through 5)use thermometer to gently stir soloution 6)When reading on thermometer stops changing mesure highest temp reached 7)Repeat with 10cm3 sodium hydroxide soloution and keep increasing by 5cm3 until 40cm3 8)Repeat this entire experiment one more time and find mean, plot it on graph
