A container with an initial volume of 1.0L is occupied by a gas at a pressure of 150kPa at 25'C. By changing the volume, the pressure of the gas increases to 600kPa as the temperature is raised to 100'C. What is the new volume? Use Combined Gas Law

Final Volume = 0.31L

Explanation:

Initial volume V1 = 1L

Initial pressure P1 = 150kPa

Initial temperature, T1 = 25'C + 273 = 298K

Final Pressure P2 = 600kPa

Final Temperature T2 = 100'C + 273 = 373K

Final Volume V2 = ?

The combined gas law is given as;

P1V1 / T1  = V2P2 / T2

150 * 1 / 298 = V2 * 600 / 373

V2 = 55950 / 178800 = 0.31L

a  solution  is always transparent, light passes through with no scattering from solute particles which are molecule in size. the  solution  is homogeneous and does not settle out. a colloid is intermediate between asolution  and a  suspension. while asuspension  will separate out a colloid will not.

i think its 5049.

i hope this !
