Kungani i-thermometer yemoto ingakhombisi kahle ngaso sonke isikhathi

Ngokungangabazeki, bekufanele uhlale emotweni ngosuku olushisayo lwasehlobo, uvule ukhiye bese ubona izinga lokushisa kumadivayisi, okucacile ukuthi liphakeme kunelangempela. Isazi sesimo sezulu uGreg Porter uchaza ukuthi kungani lokhu kwenzeka.

Imoto ikala izinga lokushisa ngento ebizwa ngokuthi "thermistor" - efana nethermometer, kodwa esikhundleni sebha yemercury noma utshwala, isebenzisa ugesi ukufunda izinguquko. Eqinisweni, izinga lokushisa liyisilinganiso sokuthi ama-molecule ahamba ngokushesha kangakanani emoyeni - esimweni sezulu esifudumele, isivinini sawo siphezulu, u-Porter uyakhumbula.

Inkinga ukuthi ezimotweni ezingama-90%, i-thermistor ifakwa khona lapho ngemuva kwe-grill radiator. Ehlobo, lapho i-asphalt ishisa kahle ngaphezu kwezinga lokushisa eliseduze, imoto izobheka nalomehluko. Lokhu kufana nokulinganisa izinga lokushisa egumbini ngokubeka i-thermometer ngonyawo kude neziko elivuthayo.

Umehluko omkhulu wokulinganisa ubonakala kakhulu lapho kupakwe imoto. Uma ushayela ngejubane eliphakeme, inzwa ithola ukushisa okuncane kakhulu okwenziwe yi-asphalt. Futhi esimweni sezulu esivamile noma esibandayo, ukufundwa kwayo ikakhulu kuhambisana namazinga okushisa wangempela.

Kodwa-ke, uParker uxwayisa ngokuthi umuntu akufanele athembele ekufundeni, ngisho nasebusika - ikakhulukazi uma umehluko wedigri elilodwa noma amabili ungasho ingozi yokuqhwala.
