by vibrating, your vocal cords force the air particles around them to vibrate (in fact resonate at the same frequency), so when you talk, the air particles vibrate at a specific frequency.
The cool air will sink and the warm air will rise.
The air is:- heated (to body temperature)- cleansed (foreign particles attach to the mucosa of the nasal cavity and thusly removed before they reach the lungs).- moistened (the humidity of the air increases)All of these mechanism are designed to help the lungs to a better supply of air.
When a liquid is heated, the particles gain kinetic energy and move faster, causing the interparticle spaces to increase. This expansion leads to a decrease in the liquid's density as the particles spread out more.
When particles are heated, they gain energy, which leads to an increase in their kinetic energy. As a result, the speed at which the particles move increases. This heightened movement can cause substances to expand and can affect their state, such as transitioning from solid to liquid or from liquid to gas. The overall effect is a more rapid and energetic motion of the particles.
When air is heated by radiation, the air molecules absorb the radiant energy and increase in kinetic energy, causing them to move more vigorously. This increased motion leads to expansion of the air, resulting in a rise in temperature.
The particles in a liguid are bonded (not as strongly as a solid which is why it flows.) when it is heated the particles vibrate and eventually the bonds break and the particles break away. This is evaporation.
The speed of the gas particles will increase as they are heated. That is why the pressure in a container increases. The particles are hitting the walls of the container with more force as they are heated.
they get excited and move around faster
The particles start moving faster and the matter expands.
It expands.

When a substance is heated, the kinetic energy of its particles increases. This leads to the particles moving faster and colliding more frequently with each other and the container they are in.
When air particles in a test tube are heated, they gain kinetic energy and move more rapidly. This increase in movement causes the particles to collide with each other and the walls of the test tube more frequently and with greater force, leading to an increase in pressure if the volume of the test tube remains constant. As a result, the temperature and pressure of the air inside the test tube rise.
In a solid, the particles start to vibrate a lot.In a liquid, the particles begin to move around faster and faster.In a gas, the particles move extremely fast through the air.
Its particles acquire greater kinetic energy.
The cool air will sink and the warm air will rise.
When the air inside a balloon is heated, its density decreases. This happens because the air molecules gain energy and move farther apart, resulting in a decrease in the air's density.
