Q2.3 Solar houses are designed to retain the heat absorbed during the day so that the stored hear can be released during the night. A botanist produces steam at 100- during the day and then allows the steam to cool to 0 °C and freeze during the night. How many kilograms of water are needed to store 200 kJ of energy for the process? (Use the laten heat of vaporization of water L. = 22.6 × 105 3/ Kg, the laten heat of fusion of water L₁= 33.5 x 104 J/Kg, and the specific heat capacity of water c = 4186 J/ kg. C. Hint: you need to use both the formula of the heat Q = mcVT and Q = mL)

Transcribed Image Text:Q2.3 Solar houses are designed to retain the heat absorbed during the day so that
the stored hear can be released during the night. A botanist produces steam at
100 during the day and then allows the steam to cool to 0 °C and freeze during
the night. How many kilograms of water are needed to store 200 kJ of energy
for the process? (Use the laten heat of vaporization of water L. = 22.6 × 105 3/
Kg, the laten heat of fusion of water L₁= 33.5 x 104 J/Kg, and the specific heat
capacity of water c = 4186 J/kg. C. Hint: you need to use both the formula of
the heat Q = mcVT and Q = mL)
