Question 7

Diametri oshib boruvchi kapillyarda suv tomchisi bor. Suv kapillyar devorlarini ho‘llasa, tomchi kapillyar bo‘ylab qaysi tomonga harakatlanadi?

Accepted Answer

kapillyarning tor uchiga tomon

Answer

kapillyarning keng uchiga tomon

Answer

tomchi harakatlanmaydi

Answer

harakat yo‘nalishi temperaturaga bog‘liq
