Convert the following temperatures to the Celsius scale. (a) 293K (b) 470K

Explanation:

293 K and 470 K on Kelvin scale are equivalent to 20°C and 197°C in Celsius scale.

It can be elaborated as follows:

The Celsius and Kelvin or Absolute temperature scales have equal units,100. Also the freezing point of water on Kelvin scale is 273 K,hence the two scales are related as follows :

T (K) = t°(C) + 273

This can be reorganized as

t°(C) = T(K) - 273

Where, T= Temperature in Kelvin scale

t= Temperature in Celsius

So,

a) 293 K in Celsius scale would be = (293-273) °C

= 20°C

Similarly,

b) 470K in Celsius scale would be = (470-273) °C

= 197°C

Final Answer:

Hence, given temperatures upon conversion to Celsius scale are as follows:

293 K = 20°C

470 K = 197°C
