It is difficult to measure the volume of a gas because?
Pressure and temperature affect different gases differently giving varied conclusions to the exact volume of that gas.
How does volume affect temperature?
Normally there is no affect. In a gas, a CHANGE of volume of a single body, will give a change in temperature. If a gas is compressed the temperature will increase. If a gas is allowed to expand, there will be a reduction in temperature. This principle is used in diesel engines, to ignite the fuel by compression and fridges, where an expansion of gas causes cooling.
What is the manipulated variable in the egg in a bottle experiment?
Egg Sucked into Bottle (Heating Variation)The variable is the temperature of the air inside the bottle, which determines its pressure and volume. When air is heated, it has higher pressure or takes up more volume. When cooled, it becomes more dense and takes up less space. With less volume in the bottle, the only way for the pressure to equalize is by pushing the egg in.Part 1: We were heating an open system "the flask." Temperature and moles were changing. Pressure and volume are being held constant. As the open system is being heated the particles speed up, have limited space to move and moles leave the flask.Part 2: We took the flask off the heater, set it on the counter and put the egg on top. Pressure and temperature are changing. Volume and moles are being held constant. When the egg was put on the flask the temperature decreased causing the molecules to slow down. This decreased the inside pressure of the flask causing the atmospheric pressure to suck the egg into the flask because it was trying to balance with the inside pressure.Egg Sucked into Bottle (Combustion Variation)There is a finite amount of gas in the bottle, nitrogen and oxygen. When combustion occurs (a burning piece of paper), the oxygen in the air combines to form solid oxides and carbon dioxide, both of which occupy less space than the initial free oxygen. Less oxygen in the bottle means lower pressure, and again the outside pressure can force the egg into the bottle.
Im a substance that has no fixed volume or shape?
A gas is a substance with no definite shape or volume.
Why do home brew beer bottles explode?
As a result of excessive pressure build up in the bottle, caused by bottling too early when there was still unfermented sugar in the brew. You must wait until all the sugars are fermented out before bottling. Then you bottle your beer adding a small amount of sugar. A secondary fermentation then occurs in the bottle which produces a small amount of carbon dioxide which gives you the fizz. Too much carbon dioxide will cause bottles to explode.
Will the volume air increases when heated?
Heating a gas increases when its volume if the pressure remains constant. Heating a gas will increase its volume, according to equation of state, law of thermodynamics. The volume is directly proportional to the temperature multiplied by the constant that is unique to each gas. The volume of the gas will expand until the gas dissipates unless it is placed into a container.
What effect does heat have on volume of air?
Heating a gas increases its' volume if the pressure remains constant. Heating a gas with the volume consant increases the pressure. See the Related Question linked to the the left of this answer: = How do you solve an Ideal Gas Law problem? =
Does gas have shape and will volume affect it?
Gas tends to take the shape of the volume it's in. If the volume is reduced, then the pressure of the gas will increase.
Does changing the temperature of a gas has no effect on the volume of the gas?
No, it does affect the volume of a gas according to the ideal gas law (PV=nRT).
How does increasing the temperature of a gas within a gas tank affect its volume?
It affects pressure, not volume.
How does the decreasing the gas volume affect the pressure of a gas?
The pressure increase.
What are examples of A change in volume in chemistry?
When a liquid is turned into a gas maybe by heating the volume of that liquid has been increased.
How much will the volume of gas increase if you heat it?
Heating gas will cause its volume to increase because the gas molecules will gain energy and move more rapidly, leading to greater space between them. The exact amount by which the volume increases will depend on factors such as the initial temperature, pressure, and the extent of heating applied.
How does pressure exerted on a gas affect its volume?
The volume decreases (smaller,less)
What volume of CO2 gas will be evolved at ntp by heating 7.3 g of magnesium hydrogen carbonate?
The volume is 1,1 mL.
How does decreasing the volume affect the volume of gas?
If the temperature remains constant, decreasing the volume will increase the pressure.
What are the 2 factors that affect gas preassure?
There are four factors that affect gas pressure. The ideal gas law enumerates them: Pressure = number of gas molecules * constant describing the particular gas's behavior * temperature of the gas / volume in which the gas is confined
