Tenzin ko bukhaar hai. Uski maa clinical thermometer use karti hain, jo shareer ka taapmaan naapne ke liye bana hai. Iska scale sirf 35 °C se 42 °C tak hai, kyunki insaan ka taapmaan isi range mein rehta hai. Har chhota nishaan 0.1 °C hai.
Saamaanya shareer taapmaan lagbhag 37 °C hai. Tenzin ki padhai 38.4 °C hai: saamaanya se zyada, isliye bukhaar hai. Clinical thermometer mein ek kink (mod) hota hai jo liquid ko wapas girne nahi deta, isliye nikaalne ke baad padh sakte hain. Digital thermometer number screen par dikhaate hain.
Garam paani ya hawa naapne ke liye laboratory thermometer use karte hain, lagbhag −10 °C se 110 °C. Isme kink nahi, isliye bulb andar rehte hue padho, aankh liquid ke sire ke barabar. Garam paani ke liye kabhi clinical thermometer mat use karo: toot sakta hai!

Socho
Clinical thermometer use se pehle kyun jhatka jaata hai, par laboratory thermometer nahi?
Ek answer
Clinical thermometer ka kink liquid ko khud wapas girne nahi deta, isliye agli padhai se pehle jhatka dekar 35 °C se neeche laana padta hai. Lab thermometer mein kink nahi; uska liquid khud girta hai.
