What are two variables held constant when testing boyles law in manometer?
Temperature & mass keep constant in Boyle's law. Volume and pressure are variable.
What happens to the volume of gas when its temperature is raised and its pressure is kept constant?
When the temperature of a gas is raised while keeping its pressure constant, the volume of the gas will also increase. This is described by Charles's Law, which states that the volume of a gas is directly proportional to its temperature when pressure is held constant.
What are two variables that must be kept constant for this experiment?
In an experiment, variables that must be kept constant are called control variables. Two common examples include temperature and pH levels. These variables should be kept constant to ensure that any changes observed in the dependent variable are a result of the independent variable being tested.
If material is heated and expands the density of the material will?
This relies on 3 things. The Pressure, volume and temperature of a Gas is all related. If the pressure is kept the same and temperature increased. The Volume (of the container) must be increased. If the Volume (of the container) is kept constant and temperature is increased the Pressure will increase. A rough idea of what will happen can be worked out by, pV=cT Where p is the pressure, V is the volume of the container, c is a constant, T is the temperature.
What is an expression of Boyle's law?
PV = constant
What will happen if the pressure on a sample of gas is raised three times and its temperature is kept constant?
The volume become one third.
Boyle's law states that the volume of a gas is inversely propertional to its pressure if the?
Temperature and amount (number of moles) is kept constant.
What will happen if the pressure on a sample of gas is raised three times and it's temperature is kept constant?
If the pressure on a sample of gas is raised three times and the temperature is kept constant, according to Boyle's Law, the volume of the gas will decrease proportionally to maintain a constant temperature. This means the gas will be compressed and occupy a smaller volume.
What electrical devices has to be kept at a constant temperature?
furnace, fridge
How is the tympanic membrane kept a constant temperature and humidity?
not sure
Which variables must be kept constant for Boyle's law to hold?
Temperature and the amount of gas (moles) must be kept constant for Boyle's law to hold true. This means the pressure and volume of a gas are inversely proportional provided the temperature and amount of gas remain constant.
When does raising the temperature of a gas increase its preasure?
This is the Gay-Lussac law: at constant volume of a gas the temperature increase when the pressure increase.
Where is the perfect meter kept?
Its kept in a museum in Paris, inside a glass case with the temperature inside the case kept the constant.
Why is 1 meter length kept in 0 degree Celsius?
All metals expand when heated and contract when cooled. It is important, therefore, that the standard metre is kept at some constant temperature. That constant temperature could be any temperature but the triple point of water is a convenient benchmark.
Gases kept at constant temperature if its temperature is change from 50 celsius to 100 celsius by what factor does the factor change?
The temperature factor increases to 1.1547, approx.
What are two variables held constant when testing boyles law in manometer?
Temperature & mass keep constant in Boyle's law. Volume and pressure are variable.
What happens to the volume of gas when its temperature is raised and its pressure is kept constant?
When the temperature of a gas is raised while keeping its pressure constant, the volume of the gas will also increase. This is described by Charles's Law, which states that the volume of a gas is directly proportional to its temperature when pressure is held constant.
