the hot-air molecules bang on each other harder.
they get exited and move faster than cold molecules
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.
when air is heated ,air pressure decreases because the molecules are
new molecules starts to form
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.
As air is heated, its volume typically expands. This happens because the heat increases the kinetic energy of the air molecules, causing them to move faster and spread out, which in turn leads to an increase in volume.
When air is heated, its molecules gain energy and move faster, causing the air to expand and become less dense. This expansion leads to a decrease in air pressure, as the heated air rises and cooler air moves in to replace it.
When air inside a balloon is heated, the molecules move faster, causing the air to expand and the balloon to inflate. The total mass of the air inside the balloon remains the same, but the density of the air decreases as it becomes less compact.
When air is heated up, the molecules within the air gain energy and move faster, causing the air to expand and become less dense. This expansion leads to a decrease in air pressure and an increase in volume.
The entropy (order of the matter) increases. Kinetics, the measurement of movement, states that when matter (atoms and molecules) are heated, they move faster and begin to collide with one another or, against the boundaries of the system they are in (flask, earl-meyer glass). Also, at certain temperatures, they will ignite, much like in the movies when a fast moving object enters the Earth's atmosphere from space.
The liquid molecules are transformed in gas molecules.
