    6. Applications * Is it possible to add heat to a body without changing its temperature? Yes. It is possible to add energy to a body (in the form of heat) and not raise its temperature by causing a phase change. When you heat ice it takes energy to convert it from ice to water, but does not change the temperature of the body until it is all converted. The principle behind this is what we call latent heat. It refers to the energy (or heat) required to change the state of a substance without...

    HG-1 THE HEAT OF FUSION OF ICE Introduction When heat flows into a system there are a number of things that can happen. One result could be a temperature rise. Or, the system might even catch fire. A third possibility is a change of state. As you know, matter exists in three states (or maybe four, the fourth being a plasma), solid, liquid and gaseous. At different temperatures, the same substance may be in different states. Each state is characterized by the way the interatomic forces act. In...

Matter is also used loosely as a general term for the substance that makes up all observable physical objects.[1][2] All objects we see with the naked eye are composed of atoms. This atomic matter is in turn made up of interacting subatomic particles—usually a nucleus of protons and neutrons, and a cloud of orbiting electrons.[3][4] Typically,...

    Pendulum is an object that, due to action of gravitational force, swings back and forth at a regular rate around a fixed point if it is pulled aside and let go. A simple pendulum consists of a weight hanging at the end of a string or wire. The path travelled by the weight is called the arc of the pendulum. The period of oscillation is the time it takes the weight to pass back and forth once over this arc. The length of the pendulum is the distance between the point at which the pendulum is...
