Question

Will the value of Specific latent heat of fusion of a Substance change if the temperature scale is changed from Celsius scale to Fahrenheit scale and from Celsius scale to kelvin scale ?

• A. i) Yes as temperature interval in Celsius scale and Fahrenheit scale is different and ii) No as temperature interval in Celsius scale and kelvin scale is same
• B. i) Yes as temperature interval in Celsius scale and Fahrenheit scale is same and ii) No as temperature interval in Celsius scale and kelvin scale is different
• C. i) No as temperature interval in Celsius scale and Fahrenheit scale is different and ii) Yes as temperature interval in Celsius scale and kelvin scale is same
• D. i) No as temperature interval in Celsius scale and Fahrenheit scale is same and ii) Yes as temperature interval in Celsius scale and kelvin scale is different
• E. i) No and ii) No as state change happens at a fixed temperature

Answer 1

The correct option is E

i) No and ii) No as state change happens at a fixed temperature

Fusion involves no change in Temperature as Fusion occurs at constant temperature which is the melting point of the substance. Hence change in Temperature scale does not affect the Latent Heat.
