7 and a half hours because if you multiply 120 by 8 you get 960 and if you multiply 120 by 7 you get 840. So it’ll take 7 full hours and 30 minutes to reach 950 km. Hope this helps and I’m sorry if it’s wrong I did my best :)
Answer:
A= 203 KJ
B= 54 Kg
Explanation:
The initial specific volumes and internal energies are obtained from A-12 for a given pressure and state. The enthalpy of the refrigerant in the supply line is determined using the saturated liquid approximation for the given temperature with data from A-11. The mass that has entered the tank is:
Δm = m₂ – m₁
= V(1/α₂ – 1/α₁)
= 0.05 (1/0.0008935 – 1/ 0.025645)Kg
= 54Kg
The heat transfer is obtained from the energy balance:
ΔU= +
m₂u₂ – m₁u₂ = +
= m₂u₂ – m₁u₁ –
= V/α₂u₂ - V/α₁u₁ –
=(0.05/0.0008935 . 116.72 – 0.05/0.025645 . 246.82 – 54.108.28) Kj
= 203 KJ
I would go with salt in ocean water as when you heat it and the water begins to evaporate it will leave the salt behind
Also water in mud as the water would evaporate and leave the mud residue behind
GOOD LUCK
