It is observed that, if the same amount of heat is supplied to water and paraffin of the same mass, the temperature rise of paraffin is higher than water. This rise is due to:


Didapati jika kuantiti haba yang sama dibekalkan kepada air dan paraffin yang sama jisim, kenaikkan suhu praffin adalah lebih tinggi daripada air. Ini adalah disebabkan oleh:

The specific latent heat of water is higher than paraffin


Haba pendam tentu air adalah lebih tinggi daripada paraffin

The specific latent heat of paraffin is higher than water


Haba pendam tentu paraffin adalah lebih tinggi daripada air

The specific heat capacity of water is higher than paraffin


Muatan haba tentu air adalah lebih tinggi daripada paraffin

The specific heat capacity of paraffin is higher than water


Muatan haba tentu paraffin adalah lebih tinggi daripada air
