Isihloko: Ingabe Iqhwa Lincibilika Ngokushesha Epulastiki noma I-Metal Plate?
(Ingabe Iqhwa Lincibilika Ngokushesha Epulasitikini Noma Ngensimbi Yensimbi?)
Emanovelini ezinganekwane zesayensi, kukhona njalo ukuqagela mayelana nokuthi izinkolelo-mbono zesayensi zingahlolwa kanjani. Omunye umbono onjalo obulokhu uthandwa kakhulu ubuhlobo phakathi kweqhwa namanzi.
Kukholakala ukuthi iqhwa linendawo encibilikayo ephansi kunamanzi. Ngokwezibalo m = C * a, lapho m izinga lokushisa ku-Celsius, c izinga lokushisa elibalulekile leqhwa ( -127°C), u-a ubude bengxenye yeqhwa njengoba kukalwa ukusuka phansi kwechibi noma ichibi, futhi P ukucindezela ohlangothini ngalunye lwechibi noma ichibi.
Ukuhlola lokhu, kungenzeka ukudala amapayipi abandayo futhi ashisayo usebenzisa amapuleti ensimbi. Kusethi eyodwa, amapayipi axhunywe esisekelweni sepayipi eyenziwe ngensimbi futhi agcinwe emazingeni okushisa aphansi kakhulu (-248°C). Khona-ke, ukushisa okuvela epayipini elishisayo kugelezela epayipini elipholile ngepuleti lensimbi elenziwe ngethusi futhi lihlala emazingeni okushisa aphezulu (930°C). Idatha eqoqwe kuwo womabili amasethi iyaqhathaniswa, futhi uma umehluko phakathi kwabo mkhulu ngokwanele, khona-ke kungenzeka ukuthi ithiyori ilungile.
Enye indlela yokuhlola ubudlelwano phakathi kweqhwa namanzi ukusebenzisa imodeli eyenziwe lula. Kulo modeli, izinga lokuncibilika kweqhwa lincike kuphela endaweni yalo. Uma indawo engaphezulu yeqhwa incane kuneyamanzi, khona-ke izoncibilika ngokushesha. Le ndlela isebenza kahle kumashidi amancane eqhwa, kodwa hhayi ezinkulu.

Ekuphetheni, ukuthi iqhwa lincibilika ngokushesha epulasitikini noma epuleti lensimbi kuncike ezimpahleni zezinto ezisetshenziselwa ukugqumisa iqhwa. Amapayipi abandayo futhi ashisayo, Ngokolunye uhlangothi, have been shown to be effective in studying this phenomenon. By comparing the data collected from different experiments, scientists can determine the best way to study the relationship between ice and water.
