Question

If temperature scale is changed from C to F, numerical value of specific heat will

• A. increase
• B. decrease
• C. remain same
• D. nothing can be decided

Answer 1

The correct option is B decrease

$0°C=32°F$

The temperature T in degrees Fahrenheit (°F) is equal to the temperature T in degrees Celsius (°C) times 9/5 plus 32:

$T\left(°F\right)=T\left(°C\right)\times 9/5+32$

or

$T\left(°F\right)=T\left(°C\right)\times 1.8+32$

AS the magnitude of the $1^{o}C$ is 0.55 times the magnitude of $1^{o}F$

Hence numerical value of specific heat will decrease
