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

Volume‚ also referred to as dynamics‚ is one of the most important components of sound. Composers use volume as a way of controlling the emotional content and shape of a piece. It is interesting to note‚ however‚ that early composers did not generally mark their scores with instructions about volume until well into the 17th century‚ but depended upon the musicians to determine the appropriate levels of volume for a specific performance space. Composers started writing indications for dynamic levels

Heat transfer is a discipline of thermal engineering that concerns the generation‚ use‚ conversion‚ and exchange of thermal energy and heat between physical systems. Heat transfer is classified into various mechanisms‚ such as thermal conduction‚ thermal convection‚ thermal radiation‚ and transfer of energy by phase changes. Engineers also consider the transfer of mass of differing chemical species‚ either cold or hot‚ to achieve heat transfer. While these mechanisms have distinct characteristics

Specific Heat and Conservation of Energy When energy in the form of heat Q is added to a material‚ the temperature of the material rises. Note that temperature‚ in units of degrees Celsius (°C) or Kelvin (K)‚ is a measure of how hot or cold a substance is‚ while heat‚ in units of joules (J) or calories (cal)‚ is a measure of its thermal energy. 1cal = 4.19J. A measure of the efficiency with which a substance can store this heat energy is known as specific heat capacity‚ or simply the specific heat‚ . The

“Sweet Heat” I think back and visualize the days of Bonnie and Clyde in the early 1930’s and reminisce about the first V8 powered vehicles driven during that era. That vision is what comes to mind when taking a drive with my father in his Ford street rod‚ “Sweet Heat”. “Sweet Heat” is a 1931 original steel Ford Sport Coupe that has been converted to a street rod powered by a ZZ4 350 cubic inch /400 Horsepower General Motors crate engine. The name “Sweet Heat” was derived from the hot new engine
