You can use Boyle's law to calculate pressure and volume changes at a constant temperature. Boyle's law is an experimental gas law that is sometimes called Boyle-Mariotte law.

When scientists record the volume on a gas why do they also record the temperature and the pressure?

because the volume of the gas is dependent upon the temperature and pressure. This is also important in the identification of the molecular mass of an unknown gaseous element.


What usually happens in general for a gas at a constant volume?

The gas volume become constant when the pressure is increased to a point that makes the distance between the gas molecules equal to zero at this point no more increase of temperature with pressure is observed. Or if the pressure and temperature are kept constant within a system then the volume can also be constant as long as you are able to maintain the pressure and temperature at constant level.


What law does this describe law states that for a fixed amount of gas at a constant pressure the volume of a gas changes and the temperature of the gas changes too?

Charles law


How does the molar concentration at Standard temperature and pressure depend upon the identity of the gas?

Molar concentration is defined as the amount of a gas divided by the volume of gas. According to the gas identity, at standard temperature and pressure, even if the amount of the gas is constant, the volume of gas changes. Thus, the molar concentration changes depending on the gas identity.


If the temperature of a reaction increases what happens to the value of the equilibruim constant?

Equilibrium constant changes when temperature changes. For an endothermic reaction, the equilibrium constant increases with temperature while for an exothermic reaction equilibrium constant decreases with increase in temperature. Equilibrium constants are only affected by change in temperature.

What is different about Boyle's and Charle's law?

Boyle's Law and Charles' Law are both gas laws. Boyle's Law deals with the changes in pressure and volume when the temperature is constant, and Charles Law deals with changes in volume and temperature when the pressure is constant.

What happens to the pressure as the volume changes?

Pressure will decrease with (because it is inversely proportianal to) volume, if (and only if!) temperature is held constant.


Do not have definite?

Gases are highly compressible. So they don't have definite volume and pressure. As volume is reduced for a given mass pressure increases. Also as temperature changes then at constant volume pressure changes considerably. Same way for a constant pressure temperature change brings a change in the volume. Moreover gasses do not have a free surface.

How is isothermal possible in a balloon?

Isothermal is where pressure and/or volume changes, but temperature remains constant. Pressure, Volume, and Temperature are related as: PV = nRT =NkT for an ideal gas. Here, we see that since a balloon's volume is allowed to change, its pressure remains relatively constant. Whenever there is a pressure change, it'll be offset by an equivalent change in volume, thus temperature is constant.


What is a sentence for thermal expansion?

Thermal expansion is the dimensional changes exhibits by solids, liquids, and gases for changes in temperature while pressure is held constant.


What happens to the pressure of a container at a constant pressure and temperature when gas particles are added?

The pressure will increase. The reason is that the more air particles relative the volume the more of a pressure you are going to have, the same thing is true of temperature changes.

Charles law


What explains how the volume of a gas is changed in response to changes in temperature of the gas?

Charles' Law. The volume and absolute temperature of a gas are directly proportional when pressure is constant.
