The volume of a gas is doubled while the temperature is held constant?

Answer 1

.. then

EITHER the pressure is halved for the same amount (moles) of gas,

OR

the amount (moles) of gas is doubled at the same pressure,

OR

any valid combination of these possibillities.

Answer 2

The temperature will increase, if the gas is ideal or nearly so. For an ideal gas, the product of pressure and volume equals a constant times the absolute temperature. If each of the temperature and pressure of the gas is doubled, the product of pressure and volume increases by a factor of 4, and the absolute temperature must increase by the same ratio.

Answer 3

When the volume of a gas is doubled with the temperature of the gas held constant, the pressure exerted by the gas reduces. This can be explained lucidly using the kinetic theory; when the gas is kept in a container closed by a movable piston, the gas molecules collide frequently as they are compressed by the piston but if the volume is increased by raising the the piston, the gas molecules are now more spaced out and thus the number of collision per second of the gas molecules decreases and pressure being the rate of collision decreases.Therefore as seen from the above explanation, when the volume of a gas is doubled, the pressure of the gas is consequently halved. This is in accordance to Boyle's law which states that " the volume(V) of a given mass of gas is inversely proportional to the pressure(P) provided the temperature remains constant"mathematically,V=k/P where K is a constant. (There is also the Boyle's,Charle's and the gas laws involved in this.)

Answer 4

if the pressure is decreased to half value the volume becomes doubled at constant temperature.

Answer 5

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.

Answer 6

It is reduced by one half.

Answer 7

is reduced by one-half

Answer 8

The pressure increases
