What is the influence of temperature and pressure upon the solubility gas in liquids?
With increasing temperature, the solubility of a gas drops. Henry’s law describes how pressure and solubility relate to a gas.
What is the effect pressure has on the solubility a gas quizlet?
At any temperature, the solubility in liquids of gases is directly proportional the pressure above the liquid. The solubility of the gas will increase with an increasing pressure above the liquid.
Which action improves the solubility a gas in liquid?
Greater solubility is a result of an increase in pressure and temperature. A rise in pressure will result in more gas particles entering liquid to lower the partial pressure. The solubility would therefore increase.
Which step is the second in the dissolving process of?
The solute particles must be separated from the other solute particle. This requires energy to overcome the forces that attract the solute particles. Endothermic is the second stage in the process of dissolving. This energy is called lattice or kinetic energy.
Does the gas dissolve more in hot or cold waters?
The interaction between molecules of gas and water molecules determines the dissolution of a gas in water. Temperature of the water will determine how much gas can dissolve in it. Cold water can dissolve more gas than hot water.
At what hour of the day is dissolved oxygen most likely to be at its highest?
It would be 6: 00 PM, at its highest
Is oxygen added to the air by boiling water?
Boiling is not an effect on oxygen. It only alters the water’s state from liquid to gas. You may be thinking about electrolysis. Electrolysis is where a small voltage (ideally 1 volt) is applied to the water. 23 VDC) will split water molecules into oxygen (on one end) and hydrogen (on another. Boil water as many times as you like.
Why does it make sense to reboil water.
The Main Risk of Reboiled water Reboiling water causes dissolved gases to be released, making it “flat.” This can lead to superheating, which may cause the water to boil at a higher temperature than its normal boiling point, and can also result in it becoming explosively hot. It is a bad idea for water to be reboiled in a microwave.
