Answer: It will occupy at the same temperature and 475 mm Hg.
Explanation:
Boyle's Law: This law states that pressure is inversely proportional to the volume of the gas at constant temperature and number of moles.
(At constant temperature and number of moles)
(At constant temperature and number of moles)
where,
= initial pressure of gas = 760 mm Hg
= final pressure of gas = 475 mm Hg
= initial volume of gas =
= final volume of gas = ?
Putting in the values:
Thus it will occupy at the same temperature and 475 mm Hg
Answer:
Explanation:
Given parameters:
Initial temperature T₁ = 25.2°C = 25.2 + 273 = 298.2K
Initial pressure = P₁ = 0.6atm
Final temperature = 72.4°C = 72.4 + 273 = 345.4K
Unknown:
Final pressure = ?
Solution:
To solve this problem, we use an adaption of the combined gas law where the volume gas is fixed. This simplification results into:
where P and T are temperatures, 1 and 2 are initial and final temperatures.
Input the parameters and solve;
P₂ = 0.7atm
