Isihloko sokuhlola : Umphumela wokushisa ekushiseni nasesimweni sezinto
Inhloso yokuhlolwa : Ukunquma umphumela wokushisa ekushiseni kanye nesimo sezinto.
Amathuluzi nezinto zokwakha : I-Thermometer, i-heater kagesi, iqhwa.
Izinyathelo Zokuhlola:
1. Lungisa iqhwa
2. Faka iqhwa esitsheni sokushisa sikagesi.
3. Linganisa izinga lokushisa leqhwa usebenzisa i-thermometer (T), bhala phansi imiphumela yokulinganisa etafuleni, inombolo 1.
4. Xhuma isifudumezi sikagesi emthonjeni wamandla. Uma iqhwa lishiswa, limunca ukushisa, lishintshe isimo salo kanye nokushisa kwalo.
Bhala phansi okubonile kuthebula elingezansi.

Phendula imibuzo elandelayo:
– Uma elinye iqhwa selincibilikile kanti elinye iqhwa lingancibilikile, lingakanani izinga lokushisa leqhwa namanzi?
– Ngesikhathi sokushintsha okuqinile (iqhwa) kube uketshezi (amanzi), ingabe kukhona ushintsho ekushiseni?
– Lapho nje lonke iqhwa selincibilikile, izinga lokushisa = …….. o C
– Isimo soketshezi sinezinga lokushisa eliphansi kakhulu = …….. o C kanye nezinga lokushisa eliphakeme kakhulu = …….. o C
– Uma izinga lokushisa lingu-…….. o C, amanzi aqala ukushintsha abe umusi
Isiphetho
Yisho isiphetho sakho mayelana nomphumela wokushisa ekushiseni kanye nesimo sezinto.
