...specific heat of certain materials can be carried out in a simple setting in which only heating and measuring temperature are the only tasks involved on the assumption that the value of the heat or energy used is derived from a power input typically in Watts or J/s. The objective of the experiment is to find out the specific heat capacity of water by monitoring change in temperature of a water that is heated to boiling under constant time interval. Introduction The specific heat of any material determines the amount of energy needed to heat 1 kg of substance by 1 degree which is obtained through the equation Q = m*C*∆T where ‘m’ refers to the mass of material, C is the specific...

...specific heat capa of water and Metals (Aluminium and copper) by using electrical method Introduction: The experiment seeks to determine the specific heat capacity of water, copper, and aluminium. To measure the specific heat capacity of these substances, which have a certain mass, an experiment is done. The energy needed to increase one kilogramme of material by one kelvin or one-degree centigrade is the specific heat capacity (Halliday, Resnick, & Walker, 2013, pp.524). The SI unit of specific heat capacity is J kg-1K-1 (International Bureau of Weights and Measures, 2006). From the definition of heat capacity, the equation can be written as Q=m × c ×∆θ (2-1)… (1) Since... Determine the specific ...

...heat capacity of a substance with reference to its specific mass gives its specific heat capacity. Hewitt et al. (2012) define specific heat capacity, c, as the heat energy required to raise the temperature of a kilogram of a substance by 1 Kelvin. Hence: c = Q/m∆T = C/m where m is the mass of the substance in kilograms The SI unit for specific heat capacity is J(kgK)-1. Taking the example above, the specific heat capacity would be: For heating up the water in the kettle, c = 600,000J/1.6kg * 40K = 9,375 J(kgK)-1 What would be c for heating up the water in the hot water...

Why are coastal and mountainous regions often much more windy than other locations at similar latitudes Also, from this and earlier chapters on meteorology, are there other weather characteristics that are perhaps unique or different for these areas

...heated from the solar insolation faster than the water surface. This is due to the high specific heat of water. As a result, the pressure on the ground surface becomes less as compared to the pressure over the sea. This results in movement of the wind from the mainland to the sea regions due to the pressure difference... Weather Characteristics in Coastal Regions and Mountainous Regions Weather Characteristics in Coastal Regions and Mountainous Regions Occurrence of wind is due to the difference in pressure between two regions. This pressure gradient is created by the existence of temperature differences in the between two regions. Considering the coast regions, during day time, the ground surface gets h...

Number The Physical Properties of Glass and Polymer Materials PMC Report on the Physical Properties of Glass and Polymer Materials PMC. Introduction Glass and Polymer Materials (polymer matrix composites) are very essential in the industrial production of commodities for various projects. The durability of any material in its production has been a crucial aspect; a factor that calls for eventual upgrading of the raw materials. The enhancement of glass and PMC has been effected by altering their physical properties through the optical and thermal properties enhancement (Brydson, 1999). For example, the thermal properties ...

...heat loss through evaporation, the two double walls enclosing a vacuum in between them to prevent heat loss through radiation. The thermos flask therefore acts as a perfect heat insulator hence suitable for our experiment. The apparatus shall be arranged as shown in the diagram below. The procedure for carrying out the experiment begins by measuring the mass of the empty calorimeter can, mc then that of the water to be used in the same experiment mw the specific heat capacity of both the calorimeter and the water are known since they are made up of known materials. The mass of the metal sample used will be measured... ?Insert of Thermodynamics The laws of thermodynamics are a set of four laws developed...

...Heat exchangers A heat exchanger is an instrument which transfers heat energy from a hot fluid to a cold fluid,with rates being maximum while the investment and running cost being minimum. Sometimes the media is separated by a wall such that the fluids do not mix or get into direct contact. Heat exchangers have a broad area of use example being in ventilation, air conditioning and space heating. As the fluid passes through the exchanger it either lose or absorb heat due to latent heat. This makes the temperature of the fluid in the system to change, and so does the temperature of the dividing walls between the two fluids. Examples of heat exchangers are; intercoolers, preheaters, oil coolers...

...HEAT TRANSFER Due HEAT TRANSFER Introduction A distillation column is a cylinder made of metal, normally talland fitted internally with horizontal plates, which have perforations. The perforated plates promote miscible liquids separation as they ascend in the cylinder in form of a vapor. They also separate air into oxygen and nitrogen; its principal components. In the distillation column, separation of air happens in its liquid rather than its gaseous state. Distillation, which is the separation of liquid or vapor mixture into its component fractions of desired purity by heat application or removal, takes place in a distillation column...

...heat or errors prone to affect the experimental outcome. Another important parameter for measurement will be the can’s and containers specific heat capacity. This is moreso because it aid in slow or steady increase or decrease of temperature. Evidently, transfer of thermal energy between two objects is only feasible when they are at different temperatures. The experiment herein will investigate the thermal energy of a solid (ice) to liquid (water) state. In this regard, thermal energy will be lost by the ice and gained by the water.
