Why does salt produce the a greater change in osmotic pressure than sugar?
The osmotic pressure depends on the number of dissolved particles in solution. When you dissolve one mole of sugar molecules, the result is one mole of dissolved particles. When you dissolve sugar, or sodium chloride (NaCl), the salt breaks apart into two ions, Na+ and Cl-. So when you dissolve one mole of salt, you have two moles of particles in solution. If you used something like magnesium chloride, MgCl2, you'd get 3 moles of particles for each mole of MgCl2 -- one mole of Mg2+ and 2 moles of Cl-.See the Web Links for more information.
Colligative properties are physical or chemical properties?
Purely physical: depends on the number of particles rather than on the kind of them.The number influences e.g. the boiling point elevation (decreased volatility), osmotic pressure (increased osmolality), etc.
What is isomotic solution?
iso-osmotic is different to isotonic even though they have the same number of solute particles as in the inside of red blood cells in isotonic solutions movement of water in and out of the cell is the same and RBC's remain unchaged, in iso-osmotic solutions RBC swell and burst this is because the semi permeable cell membrane cannot exclude iso-osmotic solutios as it can other solutes, causing a concentration gradient
What happens to the temperature increase the number of particles what happens to the pressure?
Increasing the temperature the number of particles remain constant and the pressure increase.
How does the number of particles affect the pressure of a gas?
Increased density and temperature.
Does concentration of plasma sodium ions affect the blood osmotic pressure?
yes, the higher number of plasma sodium ions the greater the osmotic pressure.
What is the importance of isotonicity in pharmacy?
The importance of isotonicity in pharmacy is to ensure solutions do not damage tissue or produce pain when administered. Osmotic pressure is governed by the number of particles of solute in a solution. Solutions with a higher osmotic pressure cause swelling of tissues as water passes from the administration site into the tissues or blood cells.

How does reducing the volume of a gas affect its pressure if the temperature of a gas and the number of particles are constant?
At a constant temperature, the volume and the pressure are inversely proportional, that it, the greater the volume, the lesser the pressure on the gas, and viceversa.

Increasing the temperature the number of particles remain constant and the pressure increase.
How does increasing the number of particles in a contained gas affect its pressure?
It increases proportionally. This means that if you double the ammount of particles, the pressure doubles.
Does the air inside a fully pumped basketball have a lower or higher pressure than the air outside?
the higher pressure is due to a greater number of gas particles per unit volume inside the ball then in the surrounding air.
Does the number of particles affect the pressure of a gas?
Yes, it is normal.
Does the number of particles in a gas affect pressure?
Yes, it is normal.
