Answer:
The flask covered with plastic wrap will contain more water that the flas left exposed.
Explanation:
Both flask will undergo evaporation of the water inside them into gas. The plastic wrapped flask will have the gaseous water condense back to water and return to the flask while the exposed flask will have the moisture evaporate into the air around it.
Hi , well I think that you're referring to a pure substance , in other words a substance that contains only one kind of matter.
The partial pressures of gases in air at 760 mmHg are N₂ (592.8 mmHg), O₂ (159.6 mmHg) and Ar (7.6 mmHg).
<h3>What is partial pressure?</h3>
Partial pressure is the pressure of a gas in a mixture of gases.
Air is a mixture of gases with 78% N₂, 21% O₂, 1% Ar and other gases in trace amounts. The partial pressure of a gas is proportional to its percentage.
Let's calculate the partial pressures of these gases, considering that the atmospheric pressure is 760 mmHg.
pN₂ = 760 mmHg × 78% = 592.8 mmHg
pO₂ = 760 mmHg × 21% = 159.6 mmHg
pAr = 760 mmHg × 1% = 7.6 mmHg
The partial pressures of gases in air at 760 mmHg are N₂ (592.8 mmHg), O₂ (159.6 mmHg) and Ar (7.6 mmHg).
