Heat transfer Heat transfer is the transition of thermal energy from a hotter object to a cooler object ("object" in this sense designating a complex collection of particles which is capable of storing energy in many different ways). When an object or fluid is at a different temperature than its surroundings or another object‚ transfer of thermal energy‚ also known as heat transfer‚ or heat exchange‚ occurs in such a way that the body and the surroundings reach thermal equilibrium‚ this means that

How Cold Affects The Body B Y: G E N E S I S P O N C E How Cold Affects The Body The body tries to maintain body temperature by vasoconstriction and shivering. Shivering is the body’s main involuntary defense against the cold producing body heat by forcing muscles to contract and relax rapidly. Vasoconstriction is the tightening of blood vessels Vasoconstriction occurs in the uncovered skin when it is exposed to cold temperatures. The reduced blood flow in the skin conserves body heat

How Surface Area Affects the Motion of a Falling Object Introduction During this investigation‚ varying surface areas of objects will be explored in a manner observing the motion as they fall. Most predominantly‚ this motion encircles speed. Speed is calculated from the formula below‚ and hence is directly proportionate to time taken when the distance travelled remains a constant. Speed = Distance/Time Surface area is likely to affect the time taken for an object to complete a descent‚ and

Heat exchanger A heat exchanger is a device that is used to transfer thermal energy (enthalpy) between two or more fluids‚ between a solid surface and a fluid‚ or between solid particulates and a fluid‚ at different temperatures and in thermal contact. In heat exchangers‚ there are usually no external heat and work interactions. Typical applications involve heating or cooling of a fluid stream of concern and evaporation or condensation of single- or multicomponent fluid streams. In a few heat exchangers

heat exchanger is a device built for efficient heat transfer from one medium to another. The media may be separated by a solid wall‚ so that they never mix‚ or they may be in direct contact.[1] They are widely used in space heating‚ refrigeration‚ air conditioning‚ power plants‚ chemical plants‚ petrochemical plants‚ petroleum refineries‚ natural gas processing‚ and sewage treatment. One common example of a heat exchanger is the radiator in a car‚ in which the heat source‚ being a hot engine-cooling

Surface Waves: Understanding its movements I. Introduction We treat here an important wave phenomenon‚ the surface wave. It occurs in many physical systems both mechanical and electromagnetic. Mechanical surface waves can exist at the interface between two media with different densities such as the oceans and air. Ordinary sea waves and tsunamis are surface waves. Seismic events can produce both longitudinal and shear waves at the earth’s surface‚ resulting in earthquakes. Electromagnetic surface
