Changes In The State of Matter

4.2 Inquiry Experiment

Azneezal Ar-Rashid

Aim

• To study changes in states of matter

Material

• Ice cubes

Apparatus

• 50 ml beaker

• Tripod stand

• Thermometer

• Wire gauze

• Bunsen burner

Procedure

• Put the ice cubes into a beaker• Record the temperature of the ice cubes• Then, heat the ice cubes while stirrikng with the

thermometer• Record the temperature every 1 minute in the table until

the water boils• Record your observation of the changes in the state of

matter in the same table• Based on the results if the activity, draw a graph showing

temperature (axis-y) against time (axis-x)

Conclusion

• When ice cubes are heated, heat energy is absorbed by the water particles in their solid state before they change to liquid.

• When heating continues, heat energy is absorbed by the water particles in their liquid state before thy change to steam (which is gaseous state)
