Essay about Investigating The Heat Capacity Of Metals - Specific Heat Capacity of Metals Daniel Rosalez 15 November Purpose The purpose of the lab experiment will demonstrates how to set up an experiment to determine specific heat of metals. You will measure the specific heat of steel washers and a lead weight. The amount of heat released or gained by an object (q) depends on the mass of the object (m) and the change in temperature of the object (∆T). q = mC s∆T () In this equation, the proportionality constant C s is called the specific heat capacity and every substance has a characteristic value. For example, the specific heat capacity of water. Specific Heat Lab report - Free download as Word Doc .doc), PDF File .pdf), Text File .txt) or read online for free. This is the report of Heat capacity.4/5(4).

In this experiment you will measure the heat capacity of water using an electrical immersion heater. Throughout this experiment we predict that the change in temperature compared to he amount of heat added to the water will be constant thus making it proportional. The capacitors suited in the power supply, may have not been functioning properly, or they were functioning poorly, thus the power supply that was directed into our water could have been even more uneven.

Due to the fact that that electricity does not function in a digital system, it functions in an analog system; meaning that there is electrical noise, and thus that you will never have precision. We were supposed to set this at 6 volts; however, we will never truly have 6 volts.

Now accompany this by bad capacitors to filter the power, we will have some immense electrical noise. The water is tap water; it is not pure distilled water. Thus it is contaminated, and thus we cannot get a percent pure result using only water. The measurement of water added into the calorimeter was eyeballed to the best of our abilities, however, it is not exact, but an estimation.

The thermometer does not record our results perfectly. We always round to get the best number possible, thus we forsake the decimal placements, which can have an impact on our precision. The specific heat capacity of a solid or liquid is defined as the quantity of heat required to change the temperature of a unit mass of a substance through a unit change in temperature. Specific heat capacity lab report result from this experiment was somewhat close to the specific heat capacity for water, but still off the mark.

Our experiment could have used specific heat capacity lab report digital system to reduce the amount of electrical noise and make volts entering the water constant. Another aspect of the experiment that was not perfect was the use of non-distilled water.

Without the use of non-distilled water the total heat capacity could not possibly have been measured. In the world heat capacity is used on many different levels. One thing that affects most people, in Canada especially is the efficiency of their furnace. Experts are able to find out the efficiency of our furnace thus finding the most efficient and cheapest way of warming our homes during the winter. Another application that heat capacity is commonly used is during the creation of certain types of pots and pans.

The pans must reach high levels of heat to cook the food while the handle must remain cool so that the cook will be able to hold it to put the food in plates.

To achieve this, the pots must be made with something with a low heat capacity, such as aluminum, specific heat capacity lab report, while the handles must be made with something with a high heat capacity, specific heat capacity lab report, such as plastic. Throughout this experiment the heat capacity of water was proven to be proportional. This was proved by graphing the change in temperature and change in energy and the graph showing a straight, diagonal line showing the proportionality of heat capacity.
