1. MATTER IN OUR SURROUNDINGS
easy
Convert the following temperatures to the Celsius scale.
$(a)$ $293 \,K $
$(b)$ $470 \,K$
A
$200\,^oC$ and $190\,^oC$
B
$20\,^oC$ and $197\,^oC$
C
$15\,^oC$ and $200\,^oC$
D
$25\,^oC$ and $195\,^oC$
Solution
In order to covert temperature from Kelvin to Celsius scale, we have to subtract $273$ from the given value because $K – 273 = \,^oC$
$(a) \,\,293 \,K – 273 = 20\,^oC$
$(b)\, \,470\,K – 273 = 197\,^oC$
