4.2 Kelvin is -268.95 degrees Celsius.
Kelvin is a scientific scale of temperature, starting at 0K - known as "absolute zero", or -273o Celsius. Therefore 4K would be four degrees above absolute zero - -269oC
The equivalent in Celsius for 4,2 K is -268,928 oC.
4 K = -269.15 deg C = -452.47 deg F
-268.95 c
-268.8 Celsius
Water changes from a liquid to gas when boiled. (boiling point = 110 Celsius)
Freezing point - zero degrees Celsius Boiling point - 100 degrees Celsius
Well, everything has its own unique freezing/melting and boiling. Helium, has a freezing/melting point of -310 degrees Celsius, or in other words, when it is below -310 it is a solid and when it is above -310 it is a liquid.
Generally this question is asked in reference to water (which is ~100 degrees Celsius) It should be pointed out that the fact that water boils at 100 degrees Celsius and freezes at 0 degrees Celsius at one atmosphere pressure (760 mm Hg) is not a fluke. It was purposely scaled to to water. In general the boiling point is the temperature at which the vapor pressure of a liquid equals the external pressure acting on the liquid. On Earth in the open air the boiling point of a liquid depends on atmospheric pressure. As a consequence the boiling point becomes lower as the external pressure is reduced - as when you go to the peak of a mountain.
The boiling point of chlorine is -34,04 oC.The melting point of chlorine is - 101,5 oC.
Helium (He)Boiling points: 4.22 K, −268.93 °C, −452.07 °F
water's boiling point is 100 degrees Celsius.
what is the density of helium at room temperature?
Helium melts at −272.20 °C and boils at −268.93 °C
It depends what gas you are taking about liquid helium, it is the coldest we have gotten it, is -270 Celsius.
This is called the boiling point. The exact temperature depends on what the liquid is. Each liquid has its own boiling point. For example, for water the boiling point is 100 degrees Celsius. The boiling point of ammonia is -33.34 degrees Celsius. The boiling point of bromine is 58.8 degrees Celsius. If you're looking for the temperature at which a specific liquid changes to a gas, ask a new question specifically about that liquid.
liquid
The boiling point is a little over 4 Kelvin; that is, at lower temperatures it is a liquid.
Boiling point is themperature when a liquid is transformed in a gas.
the frezzing and boiling point of water?....
Helium (liquid) at 4.3K , minus 269oC, don't know Fahrenheit ;-)
Copper(I) oxide has a melting point of 1201 degrees Celsius, and a boiling point of 2000 degrees Celsius. Copper(II) oxide has a melting point of 1235 degrees Celsius, and a boiling point of 2000 degrees Celsius.
