Is 2kg a lot of weight to put on?
First things first: It’s totally normal for your weight to fluctuate 1-2kg in a day. After all the hard work and effort I put in with diet and exercise, my weight doesn’t budge. In fact, there are days when my weight increases by 1-2kg by the end of the day!”
Does India use F or C?
These countries used Fahrenheit, an imperial unit of temperature. However, by the mid-20th century, even these English-speaking countries began to adopt the metric scale, and thus Celsius. India switched in 1954, the U.K. in 1965, and Australia and New Zealand in 1969.
Which temperature scale is used for scientific work?
The Kelvin temperature scale is used by scientists because they wanted a temperature scale where zero reflects the complete absence of thermal energy.
What is the range of laboratory thermometer?
A laboratory thermometer, which is colloquially known as the lab thermometer, is used for measuring temperatures other than the human body temperature. It ranges from -10˚C to 110˚C. Laboratory thermometers are designed for lab purposes such as checking boiling point, freezing point, or temperature of other substances.
What liquid is used in laboratory thermometer?
mercury
Why alcohol is used in laboratory thermometer?
Answer : Alcohol is used in a laboratory thermometer instead of a clinical thermometer because alcohol has a very low freezing point as comparison to the Mercury. It is used in the cool place or region. Freezing point is the temperature at which a liquid starts changing into solid state.
Why is alcohol not used in thermometer?
An alcohol thermometer cannot be used to measure the temperature of boiling water . Alcohol thermometers are used rather than mercury thermometers in very cold regions because alcohol has a lower freezing point than mercury.
What is the freezing point of mercury?
-37.89°F (-38.83°C)
Why do thermometers use alcohol instead of water?
Mercury is used in clinical thermometers for two reasons. For a thermometer that means it rises in the tube it’s enclosed in. Alcohol is used instead of water because it has a very low freezing point which makes it suitable for use in very cold places.
Why the wall of the bulb of a thermometer is made thin?
Answer. its made of glass with very thin walls to allow the heat from sample being measured to reach the liquid quickly for fast response and quick reading (improves the quickness of response by the thermometer). — has a vacuum above the liquid column so there is no resistance to the expanding liquid.
Why do we use alcohol and mercury in thermometers?
There is a technical reason for using mercury in clinical thermometers. Mercury has a greater coefficient of thermal expansion than alcohol. This means a column of mercury will expand and rise more than a column of alcohol for the same temperature change. As a result, you can get finer readings with mercury.
