If 150 kcal of heat raises the temperature of 2.0 kg of a material by 400 f°, what is the specific heat capacity of the material? 0.75 kcal/kg ∙ c° 1.35 kcal/kg ∙ c° 0.19 kcal/kg ∙ c° 0.34 kcal/kg ∙ c°

this result can approximate 0.34Kcal/kg.ºC

Explanation:

As during the process the material only changes its temperature we use the sensible heat formula

sensible heat formula

Data

The options given to us by the unit of temperature is celsius, so we must transform from F to celsius

Now we clear the specific heat of the sensible heat formula

this result can approximate 0.34Kcal/kg.ºC
