Unit 7: Properties of Matter

By studying this chapter students will be able to: State kinetic molecular model of matter (solid, liquid and gas forms). Describe briefly the fourth state of matter i.e. Plasma. Define the term density. Compare the densities of a few solids, liquids and gases. Define the term pressure (as a force acting normally on unit area). Explain how pressure varies with force and area in the context of everyday examples. Explain that the atmosphere exerts a pressure. Describe how the height of a liquid column may be used to measure the atmospheric pressure. Describe that atmospheric pressure decreases with the increase in height above the Earth’s surface. Explain that changes in atmospheric pressure in a region may indicate a change in the weather. state Pascal’s law. Apply and demonstrate the use with examples of Pascal’s law. State relation for pressure beneath a liquid surface to depth and to density i.e.,(P=pgh) and solve problems using this equation. State Archimedes principle. Determine the density of an object using Archimedes principle. State the upthrust exerted by a liquid on a body. State principle of floatation. Explain that a force may produce a change in size and shape of a body. Define the terms stress, strain and Young’s modulus. State Hooke’s law and explain elastic limit.

• hydroelectric generation
• solar energy
• nuclear energy
• geothermal energy
• wind energy
• biomass energy
State mass energy equation and solve problems using it. Describe the process of electricity generation by drawing a block diagram of the process from fossil fuel input to electricity output. List the environmental issues associated with power generation. Explain by drawing energy flow diagrams through steady state systems such as filament lamp, a power station, a vehicle travelling at’ a constant speed on a level road. Differentiate energy sources as non renewable and renewable energy sources with examples of each. Define efficiency of a working system and calculate the efficiency of an energy conversion using the formula:
efficiency = energy output converted into the required form / total energy input
explain why a system cannot have an efficiency of 100%. Define power and calculate power from the formula: Power = work done / time taken
