Mitu yoyesera Mphamvu Kalori teradap Suhu ndi mawonekedwe a zinthu
Cholinga cha kuyeseraku Kudziwa momwe kutentha kumakhudzira kutentha ndi momwe zinthu zilili
Zida ndi zipangizo : Thermometer, Chotenthetsera chamagetsi, Ayezi.
Masitepe Oyesera:
1. Konzani ayezi
2. Ikani ayezi mu chidebe chotenthetsera chamagetsi.
3. Yesani kutentha kwa ayezi pogwiritsa ntchito thermometer (T), lembani zotsatira za muyeso mu tebulo, nambala 1.
4. Lumikizani chotenthetsera chamagetsi ku gwero lamagetsi. Ayezi akatenthedwa, amayamwa kutentha, zomwe zimasintha mawonekedwe ake ndi kutentha kwake.
Lembani zomwe mwawona mu tebulo ili m'munsimu.

Yankhani mafunso otsatirawa:
– Ngati ayezi wina wasungunuka ndipo ayezi wina sanasungunuke, kodi kutentha kwa ayezi ndi madzi kumakhala kotani?
– Pakusintha kolimba (ayezi) kukhala madzi (madzi), kodi kutentha kumasinthasintha?
– Pamene ayezi onse asungunuka, kutentha = …….. oC
– Madzi amakhala ndi kutentha kotsika kwambiri = …….. oC ndi kutentha kwakukulu = …….. oC
– Pa kutentha kwa …….. oC, madzi amayamba kusintha kukhala nthunzi
