Answer:
The final volume of the balloon is = 28.11 L
Explanation:
Initial pressure
= 1.03 atm = 104.325 K pa
Initial temperature
= 26 °c = 299 K
Initial volume
= 22.4 L
Final temperature
= 22 °c = 295 K
Final pressure
= 0.81 atm = 82 K pa
We know that
![\frac{P_{1} V_{1} }{T_{1} } = \frac{P_{2} V_{2} }{T_{2} }](https://tex.z-dn.net/?f=%5Cfrac%7BP_%7B1%7D%20V_%7B1%7D%20%7D%7BT_%7B1%7D%20%7D%20%3D%20%5Cfrac%7BP_%7B2%7D%20V_%7B2%7D%20%7D%7BT_%7B2%7D%20%7D)
Put all the values in above formula we get
![\frac{(104.325)(22.4)}{299} = \frac{(82)(V_{2} )}{295}](https://tex.z-dn.net/?f=%5Cfrac%7B%28104.325%29%2822.4%29%7D%7B299%7D%20%3D%20%5Cfrac%7B%2882%29%28V_%7B2%7D%20%29%7D%7B295%7D)
= 28.11 L
This is the final volume of the balloon.

Answer:
Liquid B because of its higher vapor pressure due to the fact that evaporation rate is directly proportional to vapor pressure
Explanation:
The vapor pressure of liquid at equilibrium is a function to the liquid's rate of evaporation. The evaporation rate and hence the vapor pressure is a measure of the propensity of the particles of the liquid to leave the surface of the liquid and exist as vapor directly above the liquid. As high evaporation rate leads to high vapor pressure, a liquid with a higher vapor pressure will evaporate faster than one with a lower vapor pressure at the same temperature and pressure.
Therefore, liquid B with a vapor pressure of 18.04 kPa at 40° C will evaporate faster than liquid A with a lower vapor pressure of 7.37 kPa at the same 40°C.
Answer:
Because the molecules of the mixture would be compact or bond together at room temperature. In this case, both gases will condense to form water (or ice, if the room temperature is prolonged) and such droplets of water will not cause a balloon to spontaneously explode at room temperature.
Explanation:
A mixture of hydrogen and oxygen will form water. Recall that the chemical formula for water is H₂O, where H represents Hydrogen and O represents Oxygen.
A balloon is a light (not thick) solid substance with a thin membrane when blown or filled with some elements or gases.
Room Temperature means cool or cold temperature. You already know that generally at room temperature, the molecules of any substance will stick together or will become less mobile (less spontaneous).
In this case, hydrogen gas and oxygen gas will go through a process called condensation - to form water - and then through the process called freezing - to form ice.
At room temperature, the gases will first change state (state of matter) from gaseous to liquid and then from liquid to solid.
This is why the balloon will NOT spontaneously explode.
