When a gas is confined in a container, it exerts pressure due to the collision of its particles with the walls of the container. This is explained by the kinetic theory of gases, which states that gas particles are in constant random motion. Temperature also plays a role in gas pressure.
When a gas is confined in a container, it exerts pressure due to the collision of its particles with the walls of the container. This is explained by the kinetic theory of gases, which states that gas particles are in constant random motion. The more collisions occur per unit time, the higher the pressure of the gas.
For example, if you squeeze a balloon, the gas inside it gets compressed, and the particles collide with the surface of the balloon more frequently, resulting in an increase in pressure.
Another factor that influences gas pressure is the temperature. According to Charles's Law, when the temperature of a gas increases, its particles move faster, leading to more frequent and energetic collisions with the container walls, thereby increasing the pressure.

Explanation:
B. enough kinetic energy only
C. sufficient potential energy only
D. favorable geometry only
Answer: A. enough kinetic energy and favorable geometry
Explanation: According to collision theory, the rate of a reaction depends upon the number of effective collisions which means the collisions which result in the formation of product which in turn depend on following two factors:-
a) Energy factor: In order for a collision to be successful, the colliding molecules must cross a energy barrier which is called as threshold energy. Thus molecules with energy less than threshold energy are not able to result into products.
b) Orientation factor: the colliding molecules must have proper orientations at the time of collision otherwise they do not result in product formation.
B. convection
C. conduction
D. vaporization
Answer:
A balanced chemical equation not only describes some of the chemical properties of substances—by showing us what substances react with what other substances to make what products—but also shows numerical relationships between the reactants and the products.
