Particles of a gas have high kinetic energy.
true or false
True. Particles of a gas have high kinetic energy because they are in constant motion and collide with each other and with the walls of their container.
True. Particles of a gas have high kinetic energy because they are constantly moving and colliding with each other and the walls of their container.
True.
To understand why particles of a gas have high kinetic energy, we can break it down as follows:
1. Gas particles: In a gas, the particles are in constant motion. Unlike solids or liquids, gas particles are not constrained in a fixed position. They move freely and randomly throughout the available space.
2. Kinetic energy: Kinetic energy is the energy associated with the motion of an object. It depends on the mass and velocity of the particles. The kinetic energy of a particle can be calculated using the formula: KE = (1/2)mv^2, where KE is the kinetic energy, m is the mass, and v is the velocity.
In the case of gas particles, they have a relatively high kinetic energy due to their random and rapid motion. Since gas particles are not tightly packed and have no strong intermolecular forces or bonds, they can move freely and collide with other particles and the container walls. These collisions result in a transfer of momentum and energy. The constant and energetic collisions of gas particles give them high kinetic energy.
