Qhov tshwj xeeb cua sov ntawm ib yam khoom yog tus naj npawb ntawm calories uas yuav tsum tau nce qhov kub ntawm ib gram los ntawm 1oC. Vim hais tias ib tug degree ntawm lub Celsius nplai yog sib npaug rau ib Kelvin, tshwj xeeb heats nyob rau hauv lub metric system yuav qhia nyob rau hauv units ntawm ob tog. cal /g-oC lub cal / g-K.
Ib yam li ntawd, tib neeg nug, ua li cas koj hloov grams rau J kg?
cal / g ↔ J / g 1 cal / g = 4.1868 J / g . cal / g ↔ J / kg 1 cal / g = 4186.799993 J / kg.
Tsis tas li ntawd, BTU lb f yog dab tsi? Cov cua kub tshwj xeeb txhais tau tias yog qhov ntau ntawm lub zog hluav taws xob (hauv Btu ) yuav tsum tau nce qhov kub ntawm ib qho phaus los ntawm ib tug degree Fahrenheit. Qhov tshwj xeeb kub ntawm dej yog 1 Btu / lb - F ,or ib Btu rau phaus ib degree Fahrenheit. Qhov tshwj xeeb kub ntawm tooj liab yog 0.092 Btu / lb - F , tsawg tshaj li ib feem kaum ntawm cov dej.
Cov lus nug tseem yog, J kg K yog dab tsi?
Ib joule ib kilogram ib kelvin ( J / kg · K ) yog ib chav SI muab tau los ntawm cov peev txheej tshwj xeeb. Ib cov khoom muaj peev xwm kub ntawm 1 J / kg · K yog tias lub zog kub ntawm ib joule yuav tsum tau nce qhov kub ntawm ib kilogram ntawm cov khoom no los ntawm ib kelvin.
Calorie tshwj xeeb kub yog dab tsi?
Cov tshwj xeeb kub yog tus nqi ntawm kub ib chav tsev loj yuav tsum tau nce qhov kub ntawm ib tug degree Celsius. Cov tshwj xeeb kub dej yog 1 calorie ntau ntau /gram °C = 4.186 joule/gram °C uas siab dua lwm yam khoom siv.

Sociobiology yog dab tsi thiab dab tsi yog qhov kev thuam loj ntawm nws?
Ib feem ntawm sociobiology cuam tshuam nrog kev coj tus cwj pwm tsis zoo feem ntau. Cov neeg thuam tau hais tias daim ntawv thov ntawm sociobiology no yog ib hom kev txiav txim siab caj ces thiab nws ua tsis tau raws li qhov nyuaj ntawm tib neeg tus cwj pwm thiab qhov cuam tshuam ntawm ib puag ncig ntawm tib neeg txoj kev loj hlob
Dab tsi yog cov hlau nplaum uas ua los ntawm qhov kev npaj ntawm electrons yog dab tsi?
Electrons yog teem rau hauv plhaub thiab orbitals nyob rau hauv ib tug atom. Yog hais tias lawv sau lub orbitals kom muaj ntau spin taw tes rau hauv qab (los yog vice versa), txhua atom yuav ua zoo li ib tug me me hlau nplaum. Thaum ib daim ntawm cov hlau tsis muaj hlau nplaum (lossis lwm yam khoom siv ferromagnetic) raug rau sab nraud magnetic teb, ob yam tshwm sim
Dab tsi yog Qhov Ib Feem Cuam Tshuam ntawm cov khoom hydrogen hauv cov methane ch4 yog dab tsi?
Cov feem pua ntawm cov ntsiab lus los ntawm Element Element Symbol Mass Percent Hydrogen H 25.132% Carbon C 74.868%
Dab tsi yog cov reagents xav tau rau PCR thiab dab tsi yog qhov ua haujlwm ntawm txhua tus?
Muaj tsib yam tshuaj reagents, lossis cov khoom xyaw, siv hauv PCR: qauv DNA, PCR primers, nucleotides, PCR tsis thiab Taq polymerase. Primers feem ntau yog siv nyob rau hauv khub, thiab DNA ntawm ob lub primers yog amplified thaum lub sij hawm PCR cov tshuaj tiv thaiv
Dab tsi yog qhov txawv ntawm Marine West Coast huab cua thiab dab tsi yog lub luag haujlwm rau cov yam ntxwv ntawd?
Cov ntsiab lus ntawm Marine West Coast Qhov kev nyab xeeb ntawm cov yam ntxwv tseem ceeb yog lub caij ntuj sov me me thiab lub caij ntuj no thiab cov nag lossis daus txhua xyoo. Qhov ecosystem no muaj kev cuam tshuam loj heev los ntawm nws qhov ze rau ntawm ntug dej hiav txwv thiab roob. Nws yog qee zaum hu ua huab cua sab hnub poob ntug dej hiav txwv lossis dej hiav txwv huab cua
