Q:

What is the specific heat capacity of vegetable oil?

A:

The specific heat capacity of vegetable oil at 25 degree Celsius is 2.0 J/g C. When measured at a different temperature, the specific heat capacity will vary.

Specific heat capacity is defined as the quantity of heat (expressed in joules or calories) required to raise the temperature of one gram of a substance by one degree (expressed in Celsius or Kelvin). The more mass a substance has, the greater is the amount of heat required to raise its temperature by one degree. Therefore, in heating up oil in a pan, more heat is needed when heating up one cup of oil compared to just one tablespoon of oil. Additionally, more heat is necessary when heating up the oil by 10 degrees compared to heating it up by just 5 degrees.

  • Q:

    What is the difference between specific heat and heat capacity?

    A:

    Heat capacity is the amount of heat needed to change the temperature of a substance by 1 degree Celsius, while specific heat is the heat needed to change the temperature of 1 gram of substance by 1 degree Celsius. Whereas heat capacity is dependent on the amount of substance, heat capacity is independent of it.
