Electrical conductivity[ edit ] Pure water containing no exogenous ions is an excellent insulatorbut not even "deionized" water is completely free of ions. Because water is such a good solvent, it almost always has some solute dissolved in it, often a salt. If water has even a tiny amount of such an impurity, then it can conduct electricity far more readily.

This experiment is carried out by using Marcet Boiler. Marcet Boiler is use for the understanding of basic properties of saturated steam. Set the temperature controller and observe the steam temperature rise as the water boils. The steam temperature and different readings is record as the boiler is heated or cooled.

As the result, the temperature increases as the pressure increase. Some of the values are not the same at the certain point.

This is because some of the errors occur along the experiment. The loss or gain of energy of the system during a process has a direct impact on the thermodynamics properties.

Two of the most important thermodynamics properties that are being investigated in this experiment are absolute pressure and temperature that are both changes during the process in the system.

The data from the experiment will be compared with the theoretical value obtained from the steam table. HE which is the bench top unit designed for the demonstration of the basic principal in thermodynamics which is boiling. HE Lab report thermodynamic the most common device used for students in the laboratory in order for them to have a better understanding the relationship between absolute pressure and temperature of saturated steam in equilibrium with water.

This experiment is also carried out to investigate between the pressure and temperature of saturated steam in equilibrium with water. Next, the results from this experiment will be compared with the theoretical value obtained from the steam table.

However, we may not be able to get an accurate value of data as it might have errors during the experiment.

By using the Marcet Boiler, we can observe that as the temperature of water increases, the pressure also increases. Thus, the temperature of water is said to be directly proportional with the pressure.

Thermodynamics is a study related between energy and entropy, which is also deal with heat and work. It is a set of theories that related to macroscopic properties, visible with naked eye which we can measure the volume, pressure and temperature.

Ideal gas law is a law in which related to pressure, temperature and also volume of an ideal gas. Unit Construction for Marcet Boiler Model: HE No Apparatus 1. Bourdon Tube Pressure Gauge 7.

Pressure Relief Valve 9. If water had been filled in the boiler, skip step no 4 and 5. Then, close the valves, V1 and V2 at the level sight tube. Do not open the valve at the water inlet port as it was highly pressurized at a higher temperature.

Capsule Summary

Experimental Procedure 1 Perform the general start-up procedures 2 If the boiler was initially filled with water, open the valves at the level sight tube V2 and V3 to check the water level. Pour in additional distilled water if necessary.

Then, close the valves. It is always important to ensure that the valves at the level sight tube are closed before turning on the heater as the level sight tube is not designed to withstand high pressure and temperature.

This step was important to remove air from the boiler as the accuracy of the experimental results will be significantly affected when air is present. Make the intervals of pressure data for 0.the system is the first law of thermodynamics. An understanding of this extended An understanding of this extended conservation of energy law is important in practical endeavors, such as the design of heat.

Thermodynamics Lab Report - Application of the Perfect Gas Laws in the Determination of Adiabatic Index of Air Cargado por qiaunus Thermodynamics Laboratory Report The laboratory was done to demonstrate how the perfect gas laws can be used to determine the adiabatic index of air at room temperature and pressure.

Thermodynamics of the Solubility of Borax Purpose: To determine the thermodynamic quantities ΔH° and ΔS° for the solvation reaction of borax in water, by measuring the solubility product constant, K lab period. At the end of lab, exchange data sets with your partner.
