If the amount of gas is decreased and the temperature and pressure stay constant, what will be the effect on its volume?

Explanation:

According to ideal gas equation, product of pressure and volume equals n times R times T.

Mathematically,         PV = nRT

where         P = pressure

                   V = volume

                   n = number of moles

                   R = gas constant

                   T = temperature

Therefore, it can be seen that volume is directly proportional to number of moles. Hence, when there is decrease in number of moles that is, decrease in the amount of gas then there will be decrease in volume also.

Thus, we can conclude that if the amount of gas is decreased and the temperature and pressure stay constant then it there will be decrease in its volume.

indicate valleys, hills, steepness and gentleness of slopes.

explanation:

contour lines on a map indicate elevation, or depth. numeric notations on contour lines refer to the level of elevation, or height about sea level.

they it depends on if one believes about radioactivity, they make a geiger counter beep but maybe it was going to beep anyway electronics do wierd things all the time or it was programmed to beep near certain metals.
