Further Activity In the world heat capacity is used on many different levels. We always round to get the best number possible, thus we forsake the decimal placements, which can have an impact on our precision. The thermometer does not record our results perfectly.
Conclusion Throughout this experiment the heat capacity of water was proven to be proportional. The measurement of water added into the calorimeter was eyeballed to the best of our abilities, however, it is not exact, but an estimation.
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. Heat Capacity of 1 Kg from data collected: Our result from this experiment was somewhat close to the specific heat capacity for water, but still off the mark.
To achieve this, the pots must be made with something with a low heat capacity, such as aluminum, while the handles must be made with something with a high heat capacity, such as plastic. The water is tap water; it is not pure distilled water.
One thing that affects most people, in Canada especially is the efficiency of their furnace.
Now accompany this by bad capacitors to filter the power, we will have some immense electrical noise. Another aspect of the experiment that was not perfect was the use of non-distilled water.
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. Our experiment could have used a digital system to reduce the amount of electrical noise and make volts entering the water constant.
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.
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. Thus it is contaminated, and thus we cannot get a percent pure result using only water.
Another application that heat capacity is commonly used is during the creation of certain types of pots and pans. Without the use of non-distilled water the total heat capacity could not possibly have been measured.LAB FOUR.
2 Specific Heat of a Metal. There are five measurements that must be made to determine the specific heat of the unknown metal: 1.
Determine the mass of the piece of metal. 2. Heat the metal piece to a known temperature and measure this temperature precisely. This. 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.
Our result from this experiment was somewhat close to the specific heat capacity for water, but still off the mark. We were off by J/Kg/oC from the specific heat capacity of water given in the textbook.

ii) To find the specific heat capacity (SHC) of water. Hypothesis: As time increases so does the temperature since the water is exposed to the heated. wire for a longer period of time. Variables: The Dependent Variable is the temperature of the water, and since the Energy is calculated using temperature it is a dependent variable as well.
Physics Lab III Specific Heat Capacity Lab May 25, Abstract The specific heat capacity of various metals can be calculated and compared to accepted literature values. Dropping heated metal samples into a calorimeter filled with water and then measuring the change in the temperature of the system accomplished this.Download
