Ntu 2 ntawm 2: Siv Cryogenic Cawv
Kauj Ruam 1. Sim khov khoom
Nov yog qhov kev sim yooj yim. Siv tus nplaig ntsaws qhov khoom mus rau hauv cov cawv cryogenic kom txog thaum cov khoom khov. Nqa nws, thiab tsoo nws, yog tias koj xav tau.

Kauj Ruam 3. Ua pob
Dov lub plasticine rau hauv lub pob, thiab muab nws tso rau hauv cov cawv cryogenic. Muab nws tso rau hauv av lossis qee qhov tawv tawv, thiab saib zoo li pob tawg.
Kauj Ruam 4. Tshawb nrhiav qhov muaj peev xwm sim
Yog tias koj hla qhov kev sim uas siv cov kua nitrogen, txiav txim siab seb nws puas tuaj yeem ua tiav nrog cawv cawv. Cov kua nitrogen ua cov pa nitrogen, thaum cawv nyob ntawm qhov kub tsis txias. Xaiv qhov kev sim uas siv cov kua nitrogen tsuas yog ua kom txo qhov kub thiab txias.
Tsis txhob noj ib yam ntawm koj qhov kev sim nrog zaub mov cryogenic thiab cawv
