When air is inhaled, it quickly becomes saturated with water vapor as it passes through the moist upper airways. When a person breathes dry air, about 25 mg of water are exhaled with each breath. At 12 breaths/min, what is the rate of energy loss due to evaporation? Express your answer in both watts and Calories per day. At body temperature, the heat of vaporization ofwater is Lv = 24 × 105 J/kg.
A small amount of water of mass m=50 g in a container at temperature T=273 K is placed inside a vacuum chamber which is evacuated rapidly. As a result, part of the water freezes and becomes ice and the rest becomes vapor.
Question: What amount of water initially transforms into ice?
The latent heat of fusion (ice/water): 80 cal/g
The latent heat of vaporization (water/vapor): 600 cal/g
The molar heat of vaporization of some unknown
compound X at its normal boiling point 6.9 K is
8.8 kcal/mol. Calculate
AS
(cal/K) when 1.8 gram of compound X gas
condenses to liquid at 6.9 K and 1 atm. The
molecular weight of compound X is 3.2

Answer ______________ s (NO scientific notation ONLY Real Number)arrow_forwardA compound is burned in a bomb calorimeter that contains 1.50 kg of water. If the combustion of 0.330 moles of the compound causes the temperature of water to raise 24.0 C, what is the molar heat of combustion of the compound? The specific heat of capacity of water is 4.184 J/(g C). The answer needs to be in kJ/mol and have 0 decimal places. Your Answer: Answerarrow_forwardOne mole of water vapor at 346 K cools to 280 K. The heat given off by the cooling water vapor is absorbed by 10 mol of an ideal gas, and this heat absorption causes the gas to expand at a constant temperature of 273 K. If the final volume of the ideal gas is 24 L, determine its initial volume. The specific heat of water is 4186 J/kg °C and the latent heat of vaporization is 2.26 x 106 J/kg.
