Study of Gas Laws — Flashcards

Answer

Gas is the state of matter in which inter-particle attraction is weak and inter-particle space is very large, so particles move freely and randomly in the entire available space.

Answer

Gas particles move freely in all directions because the force of attraction between them is very weak. So a gas occupies the entire space of the vessel and takes its shape.

Answer

Gas molecules are in constant random motion. They collide with each other and with the walls of the container, and these collisions produce pressure in all directions.

Answer

Diffusion is the process of gradual mixing of two substances, kept in contact, by molecular motion. It happens because gas particles move randomly and mix quickly.

Answer

Although chlorine is heavier than air, it does not remain at the floor but spreads throughout the room. This happens due to diffusion, which causes gas particles to mix throughout the available space.

Answer

Boyle's law: Volume of a given mass of a dry gas is inversely proportional to its pressure at constant temperature. Equation: P1V1 = P2V2 = k This is a pressure-volume relationship at constant temper…

Answer

At constant temperature, an increase in pressure causes a decrease in the volume of a gas. This is the inverse relationship described by Boyle's law.

Answer

Given: P1 = 760 mm Hg, V1 = 800 cm3, V2 = 380 cm3 Boyle's law: P1V1 = P2V2 760 × 800 = P2 × 380 P2 = (760 × 800) / 380 = 1600 mm Hg Answer: 1600 mm Hg…
