Abu feels like to drink cold water. He need some icecubes. He put water in the freezer. Freezing turn solidto solid.

Abu ingin minum air sejuk. Dia perlukan ais batu. Diamasukkan air ke dalam peti sejuk. Prosespembekuanmenukarkan cecair kepada pepejal.

Upins mother wants to boil some water. She knows thatthe water is boiling because it produces steam or watervapour. Boiling changes liquid to gas.

Ibu Upin ingin menjerang air. Dia tahu bahawa air itusudah mendidih kerana terhasilnya wap air atau stim.Pendidihan menukarkan cecair kepada gas.

Ipins mother hangs clothe on the cloth line. After awhile, the cloth dries. This is because evaporationprocess occurs. Evaporation turn liquid to gas.

Ibu Upin menjemur kain di ampaian.
