What else can I help you with?
In higher pressure environments less gas can be dissolved in a solvent true or false?
False.
True or false the higher the altitude the lower the air pressure?
true?
What are true the vapor pressure of 1 m ethylene glycol C2H6O2 is the same as the vapor pressure of 1 m kCI where the solvent is water is it true or false?
False. The vapor pressure of a solution is lower than that of the pure solvent in a colligative property called Raoult's law. The vapor pressure of a solution is directly proportional to the mole fraction of the solute present, so the presence of the solute (ethylene glycol or KCl) will lower the vapor pressure compared to pure water.
Is it true or false atmosphere pressure increase with height?
False. Atmospheric pressure decreases with height. As you go higher in the atmosphere, there is less air above you, resulting in lower pressure. This is why mountaineers often experience difficulties due to the reduced oxygen levels at higher altitudes.
When you climb a mountain the air pressure increase true or false?
False, air pressure goes down as altitude increases. Air acts like water in the sense that they are both fluids. If you are on the surface of the earth you are in the bottom of the fluid just like water the pressure is higher on the bottom. So when you increase altitude you are reaching the top of the fluid therefore decreasing pressure.
Warm air has higher air pressure than cold air because the molecules are expanding?
False
An aqueous solution containing a nonvolatile solute will boil above 100 celsius at 1 ATM pressure true or false?
True. The addition of a nonvolatile solute to a solvent increases the boiling point of the solution compared to the pure solvent. This is known as boiling point elevation, and it occurs due to the decrease in vapor pressure of the solution.
A solution in which a gas is the solvent is an aqueous solution?
true false
Osmotic pressure is created by the presence in a fluid of small difusible moleules that easily move through the capillary membrane?
Osmotic pressure is the force exerted by the movement of solvent molecules across a semipermeable membrane from an area of lower solute concentration to an area of higher solute concentration. This movement equalizes the concentration on both sides of the membrane. The osmotic pressure is directly proportional to the concentration of solute particles in the fluid.
Would Solubility tell you how fast a solute will dissolve true or false?
False. Solubility is a measure of how much solute can dissolve in a given solvent at a specific temperature and pressure, but it does not indicate how fast the solute will dissolve. The rate of dissolution depends on factors like surface area, stirring, temperature, and concentration gradient.
Earths surface winds generally blow from regions of higher air temp to lower temp true or false?
True. Winds are created by the movement of air from areas of high pressure to low pressure. In general, air moves from regions of higher air temperature to lower air temperature to balance out the pressure differences, creating wind patterns.
Air pressure is affected by temperature.?
Yes, air pressure is affected by temperature.When the temperature is higher the air pressure lowers and the weight of the air is lower. When air is warmer the molecules sperate and there are less molecules that can cause pressure.
