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°) | |Water |4186 | |Aluminum |900

ANALYSIS On the first part of the experiment which is the determination of specific heat of metals. The obtained value of experimental specific heat of metal of aluminum and copper are 0.2152 calg-℃ and 0.0958 cal g-℃ ‚ respectively. It is a must to work faster in performing this experiment because working in an air-conditioned room greatly affects the result of the temperature. For the temperature values‚ the final temperature of mixture should not increase more than 1 ℃ compare

Oklahoma‚ Texas‚ Kansas‚ New Mexico and Colorado were hit by hundreds of dust storms during the mid 1930s. Combined the dust storms made up one of the worst natural disasters in America’s history. The dust storms ruined lands‚ it threatened the lives of most of the population‚ some people had to move West if they could‚ becoming the biggest peacetime in America. How did it occur? Well‚ in 1900 to 1930 a lot of families rented or obtained small pieces of land in the Plain states and built farms

Heat pump From Wikipedia‚ the free encyclopedia Jump to: navigation‚ search For theoretical background‚ see Heat pump and refrigeration cycle. Outdoor components of a residential air-source heat pump A heat pump is a machine or device that transfers thermal energy from one location‚ called the "source‚" which is at a lower temperature‚ to another location called the "sink" or "heat sink"‚ which is at a higher temperature. Thus‚ heat pumps moves thermal energy opposite to the direction that

in this report is heat transfer in a concentric tube heat exchanger. A heat exchanger is a device used to transfer heat from a hot fluid to a colder fluid. Heat exchangers are widely used in the petroleum industry for various reasons. Some of the most important reasons are theta heat exchangers increase the process efficiency‚ conserve energy‚ reduce maintenance and provide employee safety among many other reasons. The main objectives of the lab study were to determine the heat transfer rate‚ the

Healthy Lifestyle The majority of individuals that try to improve their condition eventually drift back into old habits such as not smoking and avoiding over weight‚ and fall short of their goals‚ feeling discouraged and even more confused about how to effectively begin living a healthy lifestyle. It is really important people know that a healthy lifestyle involves eating a nutritious diet‚ exercising regularly‚ and getting enough sleep at night; if people get conscious about these ways to keep

A heat detector is a fire alarm device designed to respond when the convected thermal energy of a fire increases the temperature of a heat sensitive element. The thermal mass and conductivity of the element regulate the rate flow of heat into the element. All heat detectors have this thermal lag. Heat detectors have two main classifications of operation‚ "rate-of-rise" and "fixed temperature." |Contents | |

Changes: Job and Lifestyle The construction of the Three Gorges Dam which has caused migration‚ changes in the lifestyle as well as choice of job of the local people of Fengjie‚ Chaina have been depicted in the movie “Still life”by Jia Zhang-Ke. The movie is mostly based on social issues. Additionally‚ it visualizes and emphasizes on how people’s life change when they become victims of floods and dam constructions; however‚ it never comes to a standstill.
