Explanation:
According to the psychrometric chart at dry bulb temperature of
and RH 70%, the absolute humidity = 0.011 kg/kg dry air
Formula to calculate humid volume is as follows.
dry air = 
= 
= 
= 0.847
dry air
Hence, humid volume of air is 0.847
dry air.
Specific enthalpy of dry air = specific heat capacity of dry air × dry bulb temperature
=
= 21.126 kJ/kg dry air
Hence, the specific enthalpy of the air is 21.126 kJ/kg dry air.
As per the psychrometric chart at given conditions wet bulb temperature = 17.5 
As per the psychrometric chart at given conditions dew point temperature = 15.5 
Answer:
D & E
Explanation:
I think this is dealing with latent heat and D & E would be the range where you will find solid and liquid phases in equilibrium, cuz it starts as gas at from A to B, B to C is gas and liquid equilibrium, C to D is liquid, D to E solid and liquid, and then E to F is solid.
Answer:
A. it contains a lot of matter
