Chap. 14: Energy in Thermal Processes Solids, liquids or gases have internal energy t Kinetic energy from random motion of molecules translation rotation vibration

The Simple Pendulum A pendulum is made by suspending a mass m at the end of a string of length L Find the frequency of oscillation for small displacements mg

At ordinary temperature, matter exists in one of three states Solid- has a shape and forms a surface Liquid- has no shape but forms a surface Gas-has no shape and forms no surface What do we mean by“ fluids”? F| uids are“ substances that flow
