HEAT TRANSFER Heat transfer‚ also known as heat flow‚ heat exchange‚ or simply heat‚ is the transfer of thermal energy from one region of matter or a physical system to another. When an object is at a different temperature from its surroundings‚ heat transfer occurs so that the body and the surroundings reach the same temperature at thermal equilibrium. Such spontaneous heat transfer always occurs from a region of high temperature to another region of lower temperature‚ as required by the second

[Energy resources]: The 2 broad types Pros and Cons of each type Ways in which they are harnessed There two main types of energy these are: 1. Potential energy 2. Kinetic energy Potential energy Potential energy is energy stored due to position. The following are some example in which potential energy can be found. 1. Wound-up spring When a spring of a dock work toy car unwinds‚ the stored energy in the spring drives the wheels and the car moves. The wound-up spring is said to posse potential

Li‚ 1 2-16-13 Solar Energy: The Energy of the Future Our Earth’s resorvoir of resources seem to be limitless‚ but with the exponential growth of the human population; the need for efficient alternative energy sources is becoming urgent. Therefore‚ research companies and individuals are focusing on creating new energy systems. Fossil fuels are are depleting and becoming more difficult to obtain. The earth will face an energy crisis in the near future if humans are not careful with their consumption

1) What was meant by the term "the earths heat budget" (5) The Earth’s Heat Budget Solar Insolation - The primary source of energy to drive our global climate system (including atmospheric and‚ to a lesser extent‚ oceanic circulation) is the heat we receive from the Sun‚ termed solar insolation. The spectrum of light which comes from the Sun is shown above. The spectrum of light in the atmosphere and at the Earth’s surface is shown below. Insolation arrives at the edge of our atmosphere primarily

The oil in orange peel is made of 95-percent limonene‚ a substance that‚ according to Greenlivingtips.com‚ is used in industrial plastics manufacturing‚ as well as being added to many household cleaners to give them a citrusy odor. The website notes that Florida ’s orange juice industry produces 5 million tons of peel waste every year‚ which is usually fed to cattle. There are many other uses for orange peel as well‚ so before you throw it away‚ consider some ways to incorporate it around your house

sense as temperature is related to the average kinetic energy of the molecules of each material: the faster they’re vibrating around‚ the hotter the object feels. We can sidestep this molecular picture by dealing with objects as a whole‚ and treating the energy transfer as the flow of heat‚ rather than kinetic energy transfer among particles. |Specific Heat for Various Materials | |Material |Specific Heat | | |(J/kg C°)

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

It has been said‚ “Not everything that is learned is contained in books.” Many people believe that not everything is contained in books while others believe that most knowledge we have known is gained from books. From my point of view‚ I believe the second one is better. Knowledge gained form books is much more important than knowledge gained from life experiences. Although not everything is contained in books‚ we still have to learn most things in books like we used to do it when we went to school
