Need asapwhich of the following is true about gases? a. gas molecules are arranged in an orderly fashion b. gas molecules are in constant motion c. hydrogen and nitrogen are liquids at room temperature d. a vapor is a solid at room temperature

The answer is B. Gas molecules are in Constant Motion.

This is supported by the Kinetic Theory of Gases, which it states that the gas particles are in constant random motion, colliding with the container that it's in.

b. gas molecules are in constant motion

ur answer would be b hope i let me know if it is right

a gas, having a molecular weight of 13 kg/kmol and a kinematic viscosity of 0.25 cm2/s, flows through a pipe 0.25 m internal diameter and 5 km long at the rate of 0.4 m3/s and is delivered at atmospheric pressure.
