Robert Boyle (Robert Boyle), 1627-1691. Many scientists are trying to learn about gas, British scientist Robert Boyle is one of the people interested in studying the properties of the gas. In the study, gas is an important variable is the variable volume 4 pressure, temperature and volume of a gas, therefore, when we wish to observe the effect of one variable, which is caused by a change of another variable. It controls two or more variables are constant, Robert Boyle, as well. When he studied the gas story He will learn that when the pressure has changed. The volume of a gas is changed by doing an experiment where the same temperature and volume of a gas is given constant. He made the experiment, however. Experiment for oil before the conclusion. He uses a tool that looks like a This tool was created by Robert huk (Robert Hooke) his assistant. Tool consists of two parts: the air tank and pump. Air tank air filling the pump section consists of Cylinder cover cylinder hose handle, which will adhere to the Tripod legs are located. Air tank valve is between open-off the air. This tool is used for Boyle the relationship between pressure and volume of the air contained in the cylinder tube by sliding the lid up and down, pumping. The volume and pressure of the air inside, it will change. Another way to find out the relationship between the pressure and volume of a gas is a u-shaped glass tubes used with mercury. The u-shaped glass tube (U) is one of the top two sides at the end of the opening at the end of the other side sealed to prevent air quantity, one inside the tubes by mercury in the tubes at the end of the turn when leveling the surface of mercury at the end of the same sides as shown. G (he leveled the same thermometer how to imagine SI) Shows whether the pressure to the surface of the mercury in the thermometer, the skin off and ends at the end of the same turn and make the atmosphere pressure experiment, that is, the gas pressure is equal to atmospheric pressure. (1 atm) Since then, more mercury into the open end of a quantity of mercury in the tube causes the beam at the end of the closed end is higher than the open. It is a difference of the aircraft thermometer as h as shown. ข. found that the volume of gas in the tube, down from the original, and to increase the quantity of mercury to another there is a difference in high volume gas thermometer h1 beam had fallen further as c. increasing quantities of mercury into a tube, he is adding pressure to the gas because of the height of the mercury in the open-ended High h or h1 as a matter of course there is pressure as a result of the gas. Make the volume of the gas in the tube is reduced in direct proportion to external pressure by the gas. The table below shows the test results for Boyle. Unit volume in cubic centimeters (cm3) The pressure is millimeters of mercury (mmHg), which is the difference of height, aircraft thermometer. Air pressure section of the experiment at that time in the oil are equal to 727.5 millimeters of mercury. When the data for oil supplied to write graph. The graph below. This graph shows the relationship between pressure (P) and volume (V) of a gas to see how the graph is a curve, the hyper-graph this Larnaca hotel is called line graph. An SEO thoem which means doing an experiment where a constant temperature from the graph is that when the pressure of the gas increases. The volume of a gas is decreased. From this graph we can find space to any point on the graph under graph line. When the drag pressure axis and axis of the volume. Area under the graph will always have the same value, such as A and B areas as shown below. If gas oil statement-based kotkho properties listed, we will have that.A = area B area. From the above experiment, we can write the graph between the pressure with many volume characteristics. One way is to keep the volume as the y-axis and the x-axis is 1/P is a straight line graph crosses the origin image. Another is the relationship between the product of pressure and volume (PV) and pressure (P) is the graph looks a straight slope equal to zero. The below image. When viewed from the right hand to left hand thread refers to the pressure (P) of a gas decreases gradually the volume (V) of a gas is increased gradually, but when viewed from the right and left. The volume of a gas decreases gradually will result in pressure of gas rising as well. From the try Boyle He has printed portfolio named New Experiments Touching the Spring of the Physico-Mechanical, the Air, and Its Effects in 1660.Kotkho statement said that constant temperature oil. The volume of gas that has a number of fixed mass changes as proportionate to the inverse pressure.When P and V is the volume of gas and pressure, respectively.K = constant. Later, many scientists have attempted a relationship of gas pressure and volume. With the precision more of several types of gas was found to be the product of the pressure and volume are not a constant pressure, according to the statement, kotkho little oil but it will depend on the pressure switch to the pressure less than one atmosphere: the graph below. From the graph, y is the product of the volume and pressure of the gas in the gas-L.atm/mol units for various types of gas pressure, the x axis is the best dash is a graph of an ideal gas. From the graph as a graph of carbon dioxide gas (CO2), oxygen gas (O2) and gas neon (Ne) all 3 types of gas pressure 1 mole of gas closer to zero, the volume of gas is equal to the increased pressure when 22.415 litres. The product of pressure and volume of a gas, carbon dioxide and oxygen gas drops. Best neon gas pressure will increase 0.5 atmosphere showed that the product of pressure and volume of a gas carbon dioxide. Is less than the neon gas of gas and oxygen, respectively, or in other words, it is at the same pressure. The volume of CO2 gas is less than gas oxygen and neon of gas. Line graph that belong to each type of gas. Look straight because this graph is the relationship between the PV equation can be written as P common straight line graph of each gas type are as follows: Which is the equation for the line that contains the y intercept is equal to, which is the product of pressure and volume of gas pressure value is equal to zero, or near zero as much as possible, which means that we let a quantity of gas that expands as full gas will expand to. So far, there are no gas is considered a pressure or the pressure of.
