Example 1: H2O boils at 100ºC and 1 atm. At what temperature will water boil

if pressure = 500 torr (1 atm / 760 torr) = 0.658 atm?

DvapH = 40.66 kJ mol-1.

Can you please show all steps and equations??? Thank you

Expert Solution

In this question we ask to find the boiling temperature of water at given pressure which is 0.658 atm using given data.After reading question we can analyze the situation which says that this problem is based on phase transition.Phase transition problem can be solved using clapeyro-clausius equation which is as below.

where is latent heat of vaporization

since we can say that so Boiling temperature will Increase as pressure increase and vice versa.

Our problem suggest that pressure is decreasing in 2nd case so boiling temperature also decrease.

Temperature of Distilled H2O = 22 *C Room (or regional) Pressure (atm) = 0.04 atm Initial Volume of Air (mL) = 10 mL Final Volume of Air (after reaction) (mL) = 40 mL Volume of O2 Collected (Final Volume - Initial Volume) = 30 mL w/ 5 mL H2O2 solution used. Given the above variables, determine the percentage of hydrogen peroxide in your solution.

Boil water in a bowl and cool in a room. The air temperature in the room is increasing linearly according to the function Ta (t) = 22 + 0.015t (t in minutes, T in ° C). Assume that Newton's Law of Cooling is satisfied: the rate of change of water temperature is proportional to the difference between the temperature of the water and the temperature of the environment. We take the water temperature after 8 minutes and find that it...

Boiling of water in an open container is a constant pressure process. On earth water boils at 100 deg C (atmospheric pressure is 101.3 kPa). If we were to boil 2 kg of water on the surface of Mars, how much energy (Q) do we need to supply? The ΔU for this process is 4750 kJ. Specific volumes of water vapor and liquid are 206.00 and 0.00100 m3/kg, respectively.
