The other objects feel the gas pressure. Whether or not they move or deform because of that pressure will depend on the how much and whether the pressure is balanced.
Remains constant.
Gas particles move in a random and constant motion, frequently colliding with each other and their surroundings. While they do not travel in perfectly straight paths, they do exhibit some degree of directional motion until they collide with other particles.
The momenta of individual objects changes. The total momentum remains constant. I have to disagree. If you have two cars that collide head on, the momentum of both vehicles stops. The ENERGY created by the impact causes usually, some reverse momentum but the momentum is lost.
They Bounce off of each other and then they stop
When two objects collide, they exert forces on each other that can cause changes in their motion, such as changes in speed or direction. The impact of the collision depends on factors like the mass and velocity of the objects involved.
You seem to have answered your own question-it is the collisions that transfer energy
When two objects collide, their total momentum remains constant if there are no external forces acting on them. This is known as the law of conservation of momentum. The momentum of the objects may change individually due to the collision, but their total momentum before and after the collision remains the same.
Thermal energy transfers from hot objects to cold objects through a process called conduction. This occurs when the particles in the hot object collide with the particles in the cold object, transferring energy and causing the cold object to heat up.
When two objects collide, they exert forces on each other. This impact can change the direction, speed, or shape of the objects, affecting their motion. The objects may bounce off each other, stick together, or deform depending on the force of the collision.
Objects would move with constant velocity or stay at rest.
This energy transfer as heat is called conduction. It occurs due to the collision of particles within a substance or between two objects in contact, leading to the transfer of kinetic energy from the faster-moving particles to the slower-moving particles, resulting in an overall increase in temperature in the substance or objects.
When an object's temperature is rising, the particles of the object gain kinetic energy, causing them to move faster and collide more frequently. This results in an increase in the object's temperature until thermal equilibrium is reached with its surroundings.
