1. Determine Differences Based on its physical properties, is a colloid a
homogeneous mixture or heterogeneous
mixture? How does it differ from a solution?

A1.50-liter sample of dry air in a cylinder exerts a pressure of 3.00 atmospheres at a temperature of 25°c. without changing the temperature, a piston is moved in the cylinder until the pressure in the cylinder is reduced to 1.00 atmospheres. the volume of the gas is
