Answer:
0.779 mol
Explanation:
Since the gas is in a bottle, the volume of the gas is constant. Assuming the temperature remains constant as well, then the gas pressure is proportional to the number of moles:
so we can write
where
p1 = 730 mm Hg = 0.96 atm is the initial pressure
n1 = 0.650 mol is the initial number of moles
p2 = 1.15 atm is the final pressure
n2 is the final number of moles
Solving for n2,
Answer:
Final temperature is located between 5 °C and 20 °C.
Explanation:
The object with high temperature transfers energy to the object with low temperature until thermal equilibrium is reached, that is, when both objects have the same temperature.
Now, let consider three scenarios:
Scenario 1 -
Scenario 2 -
Scenario 3 -
Final temperature is located between 5 °C and 20 °C.
