60
8. Two cubic meters of a gas at 30 degrees Celsius are heated at a constant pressure until the volume doubles. What is the final temperature of the gas? 60.
1. A more correct name is Boyle-Mariotte law, because Mariotte discovered this lawafter Boyle but indepedently.. 2. This law is a relation between pressure and volume at constant temperature. The equation is: pV = k where p is the pressure (variable), V is the volume (variable) , k is a constant specific for the system.
The volume doubles
The density decreases by half. You find the answer by knowing that density is equal to mass divided by the volume. If the mass stays constants and the volume is doubled, then the density is halved.
moves faster
pressure decreases
If the volume of a container of air is reduced by one half the partial pressure of the oxygen with in the container will be doubled. If the volume of a container of gas is reduced, the pressure inside the container will increase.
The pressure drops.
The initial pressure is halved. Use Boyle's law that relates pressure & volume at a constant temperature. P1V1 = P2V2 In this case the V1(initial volume) is doubled so V2 = 2V1 P2 = P1V1/V2 = P1V1/2V1 P2 = (1/2)*P1

Are you stating or asking ? If that's a statement, then it's an incorrect one. At constant temperature, the product of (pressure) x (volume) is constant. So, if the volume changed by a factor of 3, the pressure must also change by a factor of 3 ... the pressure must triple.

Temperature is proportional to energy and energy of gas particles is related to their velocity via E= 1/2mv2. So if the temperature doubles then the velocity of the individual particles increases by (4dE/m)1/2 =v
In a perfectly flexible and expandable container (pressure is constant) the volume of an ideal gas will double as the absolute temperature doubles. For a non-ideal gas and non-perfect container, your results will vary but will always be somewhat less than double.

.. thenEITHER the pressure is halved for the same amount (moles) of gas,ORthe amount (moles) of gas is doubled at the same pressure,ORany valid combination of these possibillities.
At a constant volume the pressure increase.
