As a student, it is very important to understand the basics of every single topic. Making children study for long hours is one of the most difficult tasks as they have a very short attention. Worksheets are a great tool for practicing, and practice often helps student understand concepts better and deeper, hence student should solve maximum worksheet for better understanding of the topics.
Below are given worksheets for unit seventh which cover following topics Elastic behavior, Stress-strain relationship, Hooke's law, Young's modulus, bulk modulus, shear modulus of rigidity, Poisson's ratio; elastic energy. Thermal Properties of Matter Heat, temperature, thermal expansion; thermal expansion of solids, liquids and gases, anomalous expansion of water; specific heat capacity; Cp, Cv, calorimetry, change of state - latent heat capacity.
Mechanical Properties of Fluids Pressure due to a fluid column; Pascal's law and its applications (hydraulic lift and hydraulic brakes). Effect of gravity on fluid pressure. Viscosity, Stoke’s law, terminal velocity, streamline and turbulent flow, critical velocity. Bernoulli's theorem and its applications. Surface energy and surface tension, angle of contact, excess of pressure across a curved surface, application of surface tension ideas to drops, bubbles and capillary rise.
