Q: In boyle's law which is held constant?

Write your answer...

Temperature and amount of gas.

Boyles law "happens" when the temperature is held constant and the volume and pressure change.

Temperature remain constant.

The constant k is a...constant specific for the system considered.

Pressure x Volume = Constant (at a constant temperature).

Boyles Law

boyles law

The pressure and the volume are the variables; the temperature must remain constant.

Boyles Law refers to the way gas and pressure interact. It says that the pressure of a gas times the volume of the gas will equal a constant. The constant is supposed to represent an "ideal gas."

If the pressure doubles, the volume will be halved. This is according to Boyles Law when the temperature is constant (and the number of moles is constant). Thus, P1V1 = P2V2.

The formula of Boyle law is:pressure x volume = constant (at constant temperature, in a closed system)

Boyle's Law is the inverse relationship between pressure and volume.

The Boyle (or Boyle-Mariotte) law is: the pressure and the volume in a closed system, at a constant temperature, is a constant. They are so inversely proportional.

Temperature and mass of the substance

Boyles Law deals with conditions of constant temperature. Charles' Law deals with conditions of constant pressure. From the ideal gas law of PV = nRT, when temperature is constant (Boyles Law), this can be rearranged to P1V1 = P2V2 (assuming constant number of moles of gas). When pressure is constant, it can be rearranged to V1/T1 = V2/T2 (assuming constant number of moles of gas).

Answer: No, this is not according to Charles law; however according to Boyles law this statement is correct ('true').Charles' law states: When the pressure on a sample of a gas is held constant, the Kelvin temperature and the volume will be directly related.Boyle's law describes how the pressure of a gas tends to decrease as the volume of a gas increases when temperature is held constant.

PV = nRT

Boyle's Law is the inverse relationship of pressure and volume with temperature remaining constant. Charles' Law is the direct relationship of temperature and volume with pressure remaining constant. Gay-Lussac's Law is the direct relationshipof pressure and temperature with volume remaining constant. The Combined Gas Law relates all three - volume, pressure, and temperature.

When pressure double, the volume halves. However this is only true if the number of molecules and the temperature are both in a constant state.

Robert Boyles ...Boyles law which states the principle that at a constant temperature the volume of a confined ideal gas varies inversley with its pressure.

inversely proportional

Boyles law requires that the volume increase if temp increases with pressure held constant. PV=nRT See "is Hell exothermic"

For a given mass at constant temperature, the pressure time tghe volume is a constant. pV=C

When a gas is compressed, leaving the temperature constant then boyles law has been obeyed. The volume will reduce

PV = nRT
