QUESTION:- WHY WE CANNOT USE LABORATORY Thermometer TO MESURE OUR BODY TEMPRATURE
ANSWER:- A lab thermometer can't be used to measure body temperature as it does not have a kink. The kink, in a clinical thermometer, prevents mercury levels from falling on its own so that temperature can be read even when the thermometer is no longer in contact with our body.
ya it is right given three marks
nice
but if the second person can check directly from his face

😂
🤣🤣😂😂 I am gonna be die💀💀
And I am one of that 😂😂
Me😅😅😅😅
Yea Im dead I haven't even touched my books in 1 week
We cannot measure human body temperature with laboratory thermometer as it has no kink or constriction which prevents the backflow of mercury in Clinical thermometer.
Thanks
Thankyou so much sir for the wonderfull explanation ❤
7:00 - 7:15
We cannot use laboratory thermometer to measure body temperature because it has range of temperature from -10°C to 100°C which very high as comapred to a human being temperature because it's range is from 35°C to 42°C
Wrong
Bro.. ur ans is ok but u forgot the main point which was kink....u forgot to write about kink.
We cannot use a laboratory thermometer to use a body temperature as the availability of Kenk whereas kenk does not let the mercury fall instantly which laboratory thermometers don’t have
Because for measuring body temperature we need to wait for a minute and let not the mercury fall
Minor advice it's kink not kenk
7:27 answer : we can't measure our body temp. in laboratory thermometer because it doesn't have a kink which allows us to see after taking out from a mouth
Why can't we use laboratory thermometer to measure body temperature.
Answer:
A laboratory thermometer does not have a kink and cannot stop the mercury from flowing down. So, even though the range of the body temperature is present in the thermometer, we will not be able to see the correct markings of our body temperature.
We can't measure our body temperature with laboratory thermometer because
In laboratory thermometer kink is absent.
Because the Laborartory thermometer doesn't have a kink, so the temperature rapidly falls down after we take the thermometer out of our mouths.
Understood very nicely 🎉
THANKS SIR I got 2 question one of 3 marks and 2nd of 2 marks About laboratory thermometer and you told it so good I knew both answer
we cannot measure human body temperature with laboratory thermometer because it has no kink
no we cannot use a LABORATORY THERMOMETER to measure our body temperature
Sir please explain the app how u make video
BYJUS KA DOWN FALL 💀💀💀💀☠️☠️☠️
We cannot use laboratory thermometer to measure our body temperature because it doesn't have the kink
So when we will take out the laboratory thermometer outside of our mouth after measuring the temparature will fall down rapidly
Secondly the laboratory thermometer is very long so it is difficult to handle
Thanks for the video sir ❤❤🎉🎉
We can't use a laboratory thermometer to check the temperature of a human body because it does not have kink and we won't be able to find our temperature.
7:18 b'coz it does not have boiling water range 😊😊
Sir do this type for class 8th class 8 students like 👍👇
woolen clothes don't allow heat to get reflected and keep the heat trapped in the cloth.
how do we measure the body temparature of animals
Sr, i didn't understood "Convection in nature "😢
Ranges of clinical thermometer is 35-42 ò
To bring mercury level below 35degree Celsius
My question.
but at night sea water will become very cold ❄️❄️ then how warm air from sea moves towards kand?
Name = Dakshesh
Your question is only wrong
@@mandritadana4974 you didnt understand the question
Sir kya coolness bhi energy hai
1 ans (c) °celcius
2 ans. We cannot use a laboratory thermometer for measuring body temperature because a lab thermometer is very long and has a wide range of measurement (degrees from -ve to +ve) and is difficult to handle.
3 ans (C) Both the stament are correct
I think we also have to add the kink part in answer 2, right?
We Can't use laboratory thermometer for measuring body temperature because it doesn't have a kink
correct
answer
vey nice!
Because laboratory thermometer do not consist king and their range is also high compared to clinical thermometer
😊
Nice explanation
Sir please cover ch - reproduction in plants and transportation
They are already covered by Aishwarya ma’am
Aishwarya mam has taught us start chapter already she is the biology teacher
