Leviafan [203]

38K

-391°F

Explanation:

Given temperature:

Temperature of Triton = -235°C

Unknown:

Surface temperature of Triton in °F and Kelvin

Solution:

Temperature is the degree of hotness or coldness of a body.

It is usually measured using units of kelvin, degree Celsius and degree Fahrenheit.

tK = 273 + t°C    from °C  to K

t°F = \frac{9}{5} t°C  + 32

 

tk = temperature in kelvin

 t°C = temperature in Celsius

t°F = temperature in Fahrenheit

tK = 273 + (-235) = 38K

t°F = \frac{9}{5} x (-235)   + 32  = -423 + 32 = -391°F
