it is the temperature at which paper burns
Liquid Nitrogen.
Nitrogen boils at approx -196 deg C.
It has to be cooled to below -196 degrees Celsius or -321 degrees Fahrenheit.
Answer: 196 K = -106.87 ºF
-13
Liquid nitrogen freezes at -346 °F (-210 °C, 63 K).
A substance like liquid nitrogen is used to obtain very low temperatures through a process known as cryogenic cooling. It is commonly used in scientific research and industrial applications, such as in cryopreservation of biological samples, freezing and storing food, and cooling superconducting materials. Liquid nitrogen has a boiling point of -196 degrees Celsius (-321 degrees Fahrenheit), making it suitable for achieving extremely low temperatures.
C = 77 -273 = - 196 celsius
Hydrogen liquifies at -196 degrees celsius.
Kelvin is the SI unit for temperature. Celsius is usually used in metric systems. 0 degree celsius is 273.15 Kelvin. Kelvin increases equally with celsius. So to convert celsius to kelvin, we just add 273.15 to celsius. The answer in Kelvin is 1. 329.65 .2. 77.15
196 degrees Celsius is equal to 384.8 degrees Fahrenheit.
-196
-196
Physical change, as it goes from nitrogen liquid to nitrogen gas ... No chemical change takes place.
-320.8 F
It has to be cooled to below -196 degrees Celsius or -321 degrees Fahrenheit.
196 degrees Fahrenheit or 99 degrees Celsius
Boiling is a physical change because there is no change in the chemical composition of the substance.
It's Kelvin, and it's never plural. Since both the celcius and Kelvin scales are centigrade scales (100 degrees between freezing point and boiling point of water), and 0C = 273K -196 degrees Celsius = 77K
