Answer 2

=> The most widely used temperature scale is Celsius (°C) (sometimes known as Centigrade). Water has a freezing point of 0°C and a boiling point of 100°C in Celsius.

=> Fahrenheit (°F) is the most widely used temperature. Water has a freezing point of 32°F and a boiling point of 212°F in Fahrenheit.

=> A temperature scale with no negative values is known as the Kelvin scale.

=> The formula to convert Celsius to Fahrenheit-

$F = [ C \times (\frac{9}{5}) + 32 ]$

As we have $C=40^o$

$F = [ 40 \times (\frac{9}{5}) + 32 ]$

$F=72+32$

$F=104$

Hence, $40^oC$ is equivalent to $104^oF.$

=> The formula to convert Celsius to Fahrenheit-

$T (K) = T (C)+273.15$

As we have $C=40^o$

$T (K) = 40 + 273.15 = 313.15 K$

Hence, $40^oC$ is equivalent to $313.15K$
