Particulate Nature of Matter for IGCSE CIE Skills required 1. Know that all matter is made of particles 2. Compare All matter states according to arrangement of particles and how close they are together 3. Describe the attraction forces between these particles , and the type and speed of particles motion 4. Compare physical and chemical changes to matter 5. Explain what is meant by Evaporation Boiling Condensation Melting Freezing Sublimation 6. Show how changes of physical states can be explained according to kinetic theory relating effect of temperature change on particles movement , kind of attraction forces and the effect on matter structure 7. Effect of temperature and pressure on motion of gas particles 8. Explain Random motion of particles (Brownian motion) and how particles random movement and collision in liquids and gases prove the kinetic theory of matter , and how particles move randomly due to being bombarded by other moving particles 9 Define and understand what is Diffusion as movement of particles from high to low concentration 10 Understand why diffusion occurs only in liquid and gas states but not in solid state 11 Describe and explain how the rate of diffusion depends on molecular mass and how the smaller the mass the greater the average speed of molecules (all molecules have same average kinetic energy at the same temperature , so smaller molecules make particles diffuse faster

What are we expecting from you? 1. Do’s Find a clean, quiet space and dress appropriately. Let all household members know when and where you will be in class, and ask them not to disturb you. Make sure your full name shows up appropriately. Be aware of your background, lighting, and noise. Mute until you are required to talk. Use the Zoom functions to communicate if needed (chat, raise your hand, answer yes/no, etc.). Use an appropriate zoom background if you wish. Turn off/silence cell phone and close other windows on your computer. Be on time to class. Communicate with your instructor (via their preferred communication method listed on the syllabus) if you will be late or if you lose your connection during class. Pay attention! Maintain eye contact with the speaker on the screen. Be prepared to take notes (on your computer or in a designated notebook) or to access course material (have textbook, D2L course page, or readings available). 2. Don’ts Enter a zoom that you weren't invited to, share the zoom access information for your class with others, or enter under a different name. Take screenshots, cell phone pictures, or otherwise record the meeting, your classmates, or your instructor without express permission to do so. Change your name or change your zoom background during the meeting. Walk around during the class meeting. Use the chat for side conversations with classmates. Sit in front of a window or bright light, this will make your face too dark to see. Have conversations with household members off camera. Allow household members to walk around behind you during the meeting. Engage in texting, social media, work from other classes, or other distractions while in class Frequently asked questions

Methods of purification IGCSE CHEMISTRY CAMBRIDGE 2.Experimental Techniques 2.1 Measurement Back to Chapter 2 Menu Notes : Name appropriate apparatus for the measurement of time temperature mass and volume .including burettes pipettes and measuring cylinders. ● Appropriate apparatus for measuring of Time: stopwatch/clock Temperature: thermometer Mass: balance Volume: measuring cylinder, burette, pipette    Temperature Temperature is measured with a thermometer which can give readings to the nearest degree Celsius Digital thermometers are more precise than regular thermometers The units of temperature are degrees Celsius Time Time can be measured using a stopwatch accurate to one or two decimal places The units of time are seconds or minutes Mass Mass is measured using a digital balance with readings to two decimal places. 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
