| Benzene Gas - C6H6 | |
|---|---|
| Qhov kub thiab txias - T - (K) | Tshwj xeeb kub -cp - (kJ / (kg K)) |
| 350 | 1.255 |
| 375 | 1.347 |
| 400 | 1.435 |
Tom qab ntawd, qhov kub ntawm kev tsim ntawm benzene yog dab tsi?
Tus qauv enthalpy ntawm formationofbenzene , C6H6, yog +49.2KJ/mole.
ntawm qhov kub thiab txias yog benzene kua thiab roj? Benzene Kub taw tes ntawm atmospheric pressureis80 ° C (176 ° F), thiab li no, tshuaj benzene yuav tsum tau ua kom nyob twj ywm ua kua ntawm siab dua kub tshaj qhov ntawd.
Ib yam li ntawd, nws raug nug, kuv yuav suav cov cua sov li cas?
Nkag mus rau cov ntaub ntawv tsim nyog thiab tom qab ntawd nyem rau ntawm activetextabove rau qhov ntau koj xav xam
- Rau qhov hnyav m = gm = kg.
- nrog tshwj xeeb kub c = cal / gm ° C = joule / gm ° C,
- pib kub Ti =°C = K =°F.
- thiab zaum kawg kub Tf =°C = K =°F,
- Q = calories = kcal = x 10^cal.
- Q = joules = x 10^joules.
Puas yog benzene khoom lossis kua?
Benzene yog lub npe ntawm aromatichydrocarbon, C6H6. Hauv ua kua daim ntawv, tshuaj benzene yog ntshiab, tsis muaj xim thiab flammable. Hauv chav sov, ua kua benzene evaporates yooj yim rau hauv huab cua, thiab tuaj yeem yaj hauv dej. Hauv ib puag ncig, tshuaj benzene tuaj yeem muaj nyob hauv huab cua, dej, thiab av.
