Temperature kya hai?

Short mein jawab

Temperature (taapmaan) batata hai ki koi cheez kitni garam ya thandi hai, aur ye iska bharosemand naap hai. Garam cheez ka temperature thandi cheez se zyada hota hai. Temperature thermometer se naapte hain. Common units degree Celsius (°C) aur degree Fahrenheit (°F) hain, aur SI unit kelvin (K) hai.

Haath se garam-thanda kyun nahi pehchaan sakte?

Ye ghar pe kisi bade ke saath try karo. Ek haath fridge ke thande paani wale bowl mein aur doosra halke garam (bahut garam nahi) paani wale bowl mein ek minute rakho. Ab dono haath normal tap ke paani wale bowl mein daalo.

Jo haath thande paani mein tha, use tap ka paani garam lagega. Jo haath garam paani mein tha, use wahi paani thanda lagega. Paani ka temperature to ek hi hai, lekin har haath use pichhli cheez se compare kar raha hai.

Matlab chhoona dhokha de sakta hai. Koi cheez kitni garam ya thandi hai, ye sahi-sahi jaanne ke liye naap chahiye, aur wo naap hai uska temperature.

To temperature kya batata hai?

Temperature kisi cheez ki garmi ya thandak ka bharosemand naap hai.

  • Garam cheez ka temperature zyada hota hai.
  • Thandi cheez ka temperature kam hota hai.
  • Do temperatures ka fark batata hai ki ek cheez doosri se kitni zyada garam hai.

Temperature naapne wale device ko thermometer (taapmaapi) kehte hain. Is chapter mein do tarah ke thermometers milenge: body temperature ke liye clinical thermometer, aur baaki lagbhag sab cheezon ke liye laboratory thermometer. Dekho clinical aur laboratory thermometer ka fark.

Temperature ki units kya hain?

Teen scales yaad rakho. Har scale ka naam us scientist ke naam pe hai jisne use banaya.

Scale (unit)SymbolKahan use hota hai
Celsius (degree Celsius)°CGhar aur school ke zyadatar thermometers
Fahrenheit (degree Fahrenheit)°FKuch digital thermometers; science mein kam
Kelvin (kelvin)KScience. Kelvin temperature ki SI unit hai

37.0 °C wala healthy body Fahrenheit thermometer pe 98.6 °F padhega. Temperature wahi hai, bas alag scale pe likha hai.

Teen thermometers jo ek hi body temperature ko 37.0 °C, 98.6 °F aur 310.15 K dikhate hain
Ek temperature, teen scales

°C ko kelvin mein kaise badlein?

Celsius wali value mein 273.15 jodo:

Temperature in K = temperature in °C + 273.15

  • 37.0 °C → 37.0 + 273.15 = 310.15 K
  • 25 °C → 25 + 273.15 = 298.15 K
  • 0 °C → 0 + 273.15 = 273.15 K

Kelvin se wapas Celsius mein jaana ho to 273.15 ghatao. Jaise 300 K − 273.15 = 26.85 °C.

Temperature kaise likhte hain?

Ye chhote rules science likhne ka sahi tareeka hain:

  1. Number aur unit ke beech space chhodo: 37 °C, 37°C nahi.
  2. Scales ke naam capital letter se shuru hote hain: Celsius, Fahrenheit, Kelvin.
  3. Unit ke naam mein “degree” chhote letter se (degree Celsius), aur “kelvin” chhote k se likhte hain.
  4. Symbols hain °C, °F aur K. K ke saath degree sign nahi lagta.
  5. Ek se zyada ho to “degrees” likho: 25 degrees Celsius.

Normal body temperature kitna hota hai?

Healthy insaan ka normal body temperature 37.0 °C maana jaata hai. Ye bahut saare healthy logon ka average hai, isliye ek bilkul healthy insaan ka temperature isse thoda upar ya neeche ho sakta hai. Tumhara temperature umar, din ke time aur tum kitne active rahe ho, isse bhi thoda badalta hai.

Insaan ka body temperature normally 35 °C se neeche ya 42 °C se upar nahi jaata. Jab ye normal se zyada ho, to kehte hain bukhaar (fever) hai. Kitna bukhaar hai, ye maathe ko chhoone se nahi, thermometer se pata chalta hai.

Practice karo

  1. Garam cheez ka temperature thandi cheez se ______ hota hai.

    1. (a) barabar
    2. (b) kam
    3. (c) zyada
    4. (d) zero
    Jawab dekho

    Jawab: (c) zyada

  2. Inme se temperature ki SI unit kaunsi hai?

    1. (a) degree Celsius
    2. (b) kelvin
    3. (c) degree Fahrenheit
    4. (d) metre
    Jawab dekho

    Jawab: (b) kelvin

  3. Kaunsa temperature sahi likha hai?

    1. (a) 37°C
    2. (b) 37 °c
    3. (c) 37 °C
    4. (d) 37 C°
    Jawab dekho

    Jawab: (c) 37 °C Number aur unit ke beech space chhodo, aur symbol °C capital C ke saath likho.

  4. 20 °C ko kelvin mein badlo.

    Jawab dekho

    Jawab: 20 + 273.15 = 293.15 K

  5. Sirf chhoo kar temperature sahi kyun nahi bata sakte?

    Jawab dekho

    Jawab: Haath kisi cheez ko usse compare karte hain jo unhone abhi-abhi chhui thi. Isliye wahi paani ek haath ko garam aur doosre ko thanda lag sakta hai. Thermometer sahi reading deta hai.

Students ke sawal

Kya temperature aur heat ek hi cheez hain?

Nahi. Temperature batata hai ki cheez kitni garam ya thandi hai. Heat wo energy hai jo garam cheez se thandi cheez ki taraf jaati hai. Heat ke baare mein aage ki classes mein padhoge.

Temperature ki SI unit kya hai?

Kelvin, jise K likhte hain. 300 K likhte hain, degree sign ke bina.

Log alag-alag hain, phir normal body temperature 37.0 °C kyun?

37.0 °C bahut saare healthy logon ka average hai. Ek bilkul healthy insaan ka temperature isse thoda upar ya neeche ho sakta hai, umar, din ke time aur activity ke hisaab se.

Sabse kam temperature kitna ho sakta hai?

Scientists ke hisaab se ye −273.15 °C ke kareeb hai, yaani 0 K. Ise absolute zero kehte hain. Sabse zyada temperature ki koi limit nahi maani jaati.
