How fast the gas diffuses depends on two factors 1 The mass of the particles The rate of diffusion of gases Gases diffuse because the particles collide with other particles, and bounce off in all directions . if you do not know what exactly diffusion means click here first Note that gases do not all diffuse at the same rate. The speed with which the gases diffuse depends on these two factors: 1 The mass of the particles The particles in hydrogen chloride gas are twice as heavy as those in ammonia gas. Cotton wool soaked in ammonia solution is put into one end of a long tube (at A below). It gives off ammonia gas.  At the same time, cotton wool soaked in hydrochloric acid is put into the other end of the tube (at B). It gives off hydrogen chloride gas.  The gases diffuse along the tube. White smoke forms where they meet: The white smoke forms closer to B. So the ammonia particles have travelled further than the hydrogen chloride particles – which means they have travelled faster. The lower the mass of its particles, the faster a gas will diffuse. When particles collide and bounce away, the lighter particles will bounce further. The particles in the two gases above are molecules. The mass of a molecule is called its relative molecular mass. So The lower its relative molecular mass, the faster a gas will diffuse. 2 The temperature When a gas is heated its particles take in heat energy, and move faster. They collide with more energy, and bounce further away. So the gas diffuses faster. The higher the temperature, the faster a gas will diffuse. Diffusion Download as PDF

Units of mass commonly used are kilograms (kg) and grams (g) Volume-liquids The volume of a liquid can be determined using    several types of apparatus according to the accuracy required. For approximate volumes where accuracy is not an    important factor, measuring cylinders are used.    They are graduated (have a scale so can be used to     measure) and are available in 25 cm3, 50 cm3, 100 cm3 and 250 cm3 Pipettes are the most accurate way of measuring a fixed   volume of liquid, usually 10 cm3 or 25 cm3 Burettes are the most accurate way of measuring a   variable volume of liquid between 0 cm3 and 50 cm3   (e.g. in a titration)    Volume-gases The volume of a gas measurement is done through A gas syringe A graduated cylinder inverted in water but the gas should not be water-soluble In A gas cylinder but the position depends If the gas is heavier than air the cylinder can be used upright or if lighter than air to be used downward Measuring Cylinder Pippettes Burette Previous Topic List of Topics Download as PDF
