Hi, Can somebody help me with this question please? In humid air with a water content of 3 g / (kg dry air), liquid water is injected at a temperature of 30 ° C, after which the air temperature becomes 18 ° C and its relative humidity 50%. The total pressure is constant 1.013 bar and the mass of the dry air is 60 kg. Calculate: a) the amount of water injected; b )the air temperature before water is injected

It means that we really don't need the sun for life. In fact, I'm sure that if Pluto had a bigger atmosphere to retain more heat, and the liquid water mountains melted, t
