The volume of 400 ml of chlorine gas at 400 mm hg is decreased to 200 ml at constant temperature. what is the new gas pressure? 400 mm hg 650 mm hg 300 mm hg 800 mm hg the collision of gas molecules with the walls of its container produces temperature density volume pressure

A. Let us first assume that the gas acts like an ideal gas so that we can use the ideal gas equation:

PV = nRT

where P is pressure, V is volume, n is number of moles, R is universal gas constant and T is absolute temperature

In this case, let us assume that nRT = constant so that:

P1V1 = P2V2

400 mm Hg * 400 mL = P2 * 200 mL

P2 = 800 mm Hg

B. The collision of gas with the walls of the container produces Pressure.

differentiate (x^14(x^-2)^4with respect to the variable

the parentheses don't balance in your input.

differentiate 0 with respect to

the final answer is

0
