ﻣﻌﺎﻳﻴﺮ ﺍﻟﺒﺤﺚ Understand the nature of matter Classify solids according to stiffness, tensile strength, compressive stress and shear stress. Plot and interpret stress–strain graphs for different solid. Define and use the concept of Young’s modulus. 26. 1 Determine Young’s modulus for a variety of materials (e. g. metals, nylon, polythene). 26. 2 Relate the uses of materials to their characteristic behaviour under different types of stress and note the importance of composite materials, both natural and synthetic. Devise tests to compare different materials under stress.

ﻣﻌﺎﻳﻴﺮ ﺍﻟﺒﺤﺚ : ﺗﺎﺑﻊ 26. 3 Explain surface tension in terms of interparticle forces. Investigate the effect on the surface tension of water of adding a detergent. Apply the kinetic particle model to an ideal gas and explain, in terms of molecular size and intermolecular forces, how the behaviour of real gases deviates from the ideal model at high pressures and low temperatures. 26. 5

ﻣﻌﺎﻳﻴﺮ ﺍﻟﺒﺤﺚ : ﺗﺎﺑﻊ 26. 6 Derive, know and use the gas laws and the general gas equation PV = n. RT and show the general gas equation leads to a concept of absolute zero of temperature. Determine the laws of Boyle and Charles. Show an extrapolation of Charles’s law leads to theoretical concept of absolute zero of temperature. Solve problems relating to the changes in temperature, pressure and volume of a gas in both theoretical and real situations (e. g. bubble size in deep water, the volume of gas in a weather balloon).
