Do hot air particles move faster?
The particles in gases fly through space in all directions as individuals. When gases get hot, the particles fly faster. Faster particles hit other particles harder, pushing the particles farther apart. This causes the gas to expand.
What happens to gas particles when they heat up?
Heating a gas increases the kinetic energy of the particles, causing the gas to expand. In order to keep the pressure constant, the volume of the container must be increased when a gas is heated.
What happens to the speed of the particles if the temperature goes up Brainly?
When the temperature is increased the speed of the particles is increased because heating increases the kinetic energy of the particles of matter.
Why does a smell travel faster in hot gases?
It happens even faster in hot gases because the particles of gas move faster. Gas particles move very quickly (air particles move at 500 m/s on average at room temperature). However, a smell does not travel this fast. This is because its particles collide with each other and with particles of air very frequently.
How fast do gases spread?
The particles in a gas are moving very quickly in random directions. The speeds of the particles vary but, on average, they move quicker than they do in liquids and solids. This means that it does not take long for a gas to spread out to fill its entire container. The smell of an air freshener can spread all around a room very quickly.
Why does hot air move up and cold air down?
You are exactly right.The molecules in hot air are moving faster than the molecules in cold air. Because of this, the molecules in hot air tend to be further apart on average, giving hot air a lower density. So since cold air weighs more, it sinks, driving the hot air up.
Why is diffusion in gases so quick?
Diffusion in gases is quick because the particles in a gas move quickly. It happens even faster in hot gases because the particles of gas move faster. Gas particles move very quickly (air particles move at 500 m/s on average at room temperature). However, a smell does not travel this fast.
