A sample of argon gas is at a temperature of 20 °C. The temperature is increased to 30°C so that the volume is now 373 mL. What was the original volume?

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 is conclusions.i think so
