Humid air at 155 kPa, 40°C, and 70 percent relative humidity is cooled at constant pressure in a pipe to its dew-point temperature. Calculate the heat transfer, in kJ/kg dry air, required for this process. Use data from the tables. The heat transfer is kJ/kg dry air.

How much heat in kilojoules is evolved in converting 2.00 mol of steam at 140 ∘C∘C...

How much heat in kilojoules is evolved in converting 2.00 mol of steam at 140 ∘C∘C to ice at -20.0 ∘C∘C? The heat capacity of steam is 1.84 J/g∘CJ/g∘C and that of ice is 2.09 J/g∘CJ/g∘C. Remember that if heat is leaving the system, then q is a negative number and if heat is entering the system, then q is a positive number.
