Answer:
The heating effect of the residential heat pump will be 7.2 KJ/Sec
Explanation:
The rate of heat produced (
)
Here, Coefficient of performance = 1.6
Here, Consume of electrical power =4.5
The rate of heat produced ( ) = Coefficient of performance × Consume of electrical power
∴ = 1.6 × 4.5
= 7.2 KJ/SEC
∴ The heating effect of the residential heat pump will be 7.2 KJ/Sec
Mole percent of O2 = 10% = 0.1 moles
Mole percent of N2 = 10% = 0.1 moles
Mole percent of He = 80% = 0.8 moles
Molar Mass of O2 = (2 x 16) x 0.1 = 3.2
Molar Mass of N2 = (2 x 14) x 0.1 = 2.8
Molar Mass of He = 4 x 0.8 = 3.2
1. Molar Mass of the mixture = 3.2 + 2.8 + 3.2 = 9.2 grams
2. Since at constant volume density is proportional to mass, so the ratio of
mass will be the ratio of density.
Ratio = Molar Mass of the mixture / Molar Mass of O2 = 9.2 / 32 = 0.2875
Plants and animals use energy to produce protein, to rule the cells reaction, for cell division and to stay alive.
