Answer 0 °C + Heat required to convert 2 kg of water at 0 °C to 2 kg of water at 20 °C. Therefore, to melt 2 kg of ice 835.48 KJ of heat is required.
Answer: 19kpa
Explanation:
The total pressure of a mixture of gases is the sum of the partial pressure exacted by the individual gases.
P total = P X + P Y
From the question above:
P total = P .nitrogen + P. oxygen
123.5kpa = 104.5kpa + P. Oxygen
P. Oxygen = 123.5kpa - 104.5kpa
= 19kpa
