Helium has the lowest boiling point of any substance, at 4.2 k. part a what is this temperature in âc?

The temperatur e of Helium in °C =  -268.8 °

Temperature is one of the principal quantities that shows the degree of heat or cold from an object / space

Temperature is used as a guide to the level of heat energy from objects

Temperature measures thermal energy

The temperature of an object also depends on the kinetic energy of the object's molecules

Temperature cannot be measured by the surface of the hand because it is not accurate but can be measured by a thermometer. Temperature units include Celsius, Fahrenheit, Reamur or Kelvin

Boiling point and freezing point of Temperature units;

Boiling point : 100 °C

Freezing point: 0 °C

Boiling point : 80 °R

Freezing point: 0 °R

Boiling point : 212 °F

Freezing point: 32 °F

Boiling point : 373 °K

Freezing point: 273 °K

Whereas the temperature conversion is

°F = (9/5) °C + 32

°R = (4/5) °C

°K = °C + 273

°C = 5/9 (°F-32)

°R = 4/9 (°F-32)

°K = 5/9 (°F-32) + 273

°C = °K - 273

°R = 4/5 (°K-273)

°F = 9/5 (°K-273) + 32

°C = (5/4) °R

°F = (9/4) °R + 32

°K = °C + 273

°K = (5/4) °R + 273

Helium at 4.2 K, then the temperature in C  :

C = K - 273

C = 4.2 - 273

C = -268.8 C
