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
