Solidifying Mercury

Lub melting point ntawm mercury yog - 38.83 ° C , los yog - 37.89 degrees Fahrenheit . Mercury tuaj yeem ua kom khov los ntawm kev ua kom txias rau hauv qab nws qhov melting point.

Yog li, Mercury puas yog kua lossis roj hauv chav sov?

Mercury , piv txwv li, feem ntau pom raws li a ua kua Tab sis ntawm -40 degrees Celsius nws khov thiab hloov mus rau hauv ib khov kho . Thiab Mercury vapor ( gas ) muaj nyob rau hauv ib co particles ntawm lub teeb. Lub xeev ntawm Mercury yog nyob ntawm qhov kub . Mercury yog hlau, uas tshwm sim nyob rau hauv ua kua xeev ntawm chav kub.

Kuj Paub, peb puas tuaj yeem ua kom muaj mercury hauv chav tsev kub? Raws li niaj hnub chemistry, koj ua tsis tau solidify mercury ntawm chav tsev kub ; koj tuaj yeem ua kom muaj mercury tsuas yog tias koj coj nws mus rau -38 degrees Centigrade. Tab sis tam sim no ntawm chav kub , mercury yog khov kho tsis muaj ntxiv lawm. Qhov ntawd tsis tuaj yeem yog lub cev, lub hom phiaj science.

Tsis tas li ntawd, mercury puas tuaj yeem hloov mus ua khoom?

Mercury tau ua khov kho los ntawm kev ua kom txias hauv qab nws qhov chaw khov / melting point (-38.83 ° C ntawm 1 atm) lossis los ntawm kev nias nws txaus. Nyob rau ntawm qhov kub thiab txias, nws ua haujlwm zoo ib yam li lwm cov hlau hloov pauv, ua tau yooj yim thiab ductile, ua hluav taws xob, & c.

Lub xeev twg yog mercury ntawm 25 degrees Celsius?

kua

Qhov kub ntawm qhov hluav taws kub kub li cas?

Feem ntau hom ntoo yuav pib combusting ntawm li 300 degrees Celsius. Cov pa roj hlawv thiab nce qhov kub ntawm cov ntoo mus txog 600 degrees Celsius (1,112 degrees Fahrenheit). Thaum cov ntoo tso tawm tag nrho nws cov gases, nws tawm charcoal thiab tshauv

Dab tsi yog qhov txawv ntawm qhov pom tseeb qhov loj thiab qhov ntsuas qhov ntsuas qhov tseeb?

Dab tsi yog qhov txawv ntawm qhov pom tseeb thiab qhov tseeb? Pom meej qhov loj npaum li cas yog qhov ci ntawm lub hnub qub tshwm los ntawm lub ntiaj teb thiab nyob ntawm qhov ci thiab qhov deb ntawm lub hnub qub. Qhov loj npaum li cas yog qhov ci ntawm lub hnub qub yuav tshwm sim los ntawm tus qauv nyob deb

Dab tsi yog qhov txawv ntawm qhov sib txawv ntawm qhov sib txawv thiab qhov sib txawv ntawm qhov ntab?

Integers thiab floats yog ob yam sib txawv ntawm cov ntaub ntawv tus lej. Ib tus lej (feem ntau hu ua anint) yog tus lej tsis muaj tus lej lej. Float isa floating-point number, uas txhais tau hais tias nws yog tus lej uas muaj tus lej lej. Floats siv thaum xav tau ntau dua

Qhov cuam tshuam ntawm qhov kub thiab txias ntawm qhov sib faib coefficient yog dab tsi?

Ib qho inverse linear kev sib raug zoo tau pom ntawm qhov kub thiab txias thiab qhov sib faib coefficient. CEEB TOOM: Nyob rau hauv ib qho kev ntsuas kub, qhov sib faib coefficients isoflurane thiab sevoflurane txo qis thaum qhov kub nce. Sevoflurane qhia tau hais tias muaj kev solubility siab hauv Oxygent (TM) piv rau isoflurane
