calculate the amount of energy required to to convert 2kg of water at 34°C to ice to 0°C About the author Melody
Answer: Total heat = Heat required to convert 2Kg of ice into water at 0°C + Heat required to convert 2Kg of water at 0°C to 2Kg of water at 20°C. Heat = m (hfw) + mc∆T. Here, m(mass of ice) = 2Kg. hfw (specific latent heat of water) = 3,34,000J/Kg. C (specific heat capacity of water) = 4200JKg-1 K-1 Reply
Answer:
Total heat = Heat required to convert 2Kg of ice into water at 0°C + Heat required to convert 2Kg of water at 0°C to 2Kg of water at 20°C.
Heat = m (hfw) + mc∆T.
Here, m(mass of ice) = 2Kg.
hfw (specific latent heat of water) = 3,34,000J/Kg.
C (specific heat capacity of water) = 4200JKg-1 K-1
