What are the functions of air expansion apparatus?
a device that demonstrate how heat affects the volume of a gas.
What is sound produced due to rapid expansion and contraction of heated air called?
The sound produced due to the rapid expansion and contraction of heated air is called a "thermal expansion wave" or a "heat-induced acoustic wave." When air is rapidly heated, it expands quickly, creating a pressure wave that propagates as sound. This phenomenon is commonly observed in various natural and man-made processes, such as thunder during a lightning strike or the popping sound of a heated metal object being cooled rapidly.
Does Air expand when its is heated?
Yes, when air is heated, it expands because the particles gain energy and move farther apart, increasing its volume. This expansion causes the air to become less dense and rise.
What happens to air heated by radiation?
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.
What happens when you heat air?
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.
What happens to the air when heated up?
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.
What is the definition for thunder?
A loud, explosive, resounding noise produced by the explosive expansion of air heated by a lightining discharge. (Dictionary.com)
Is hot air balloon an example of thermal expansion in gas?
Yes, a hot air balloon is an example of thermal expansion in gas. As the air inside the balloon is heated, it expands and becomes less dense than the surrounding air, causing the balloon to rise.
Air expansion and contraction?
Air expands when heated because the molecules gain energy and move further apart. This increases the volume that the air occupies. Conversely, air contracts when cooled because the molecules lose energy and move closer together, decreasing the volume occupied by the air.
How does the thunder shakes the house during a storm?
During a storm, thunder is caused by the rapid expansion of air heated by lightning. This sudden expansion creates shock waves that travel through the air, causing vibrations that can shake the house.
When air is heated it a contracts b becomes heavier c condenses d expands?
When air is heated, it d) expands. As the temperature increases, the molecules move faster and spread apart, leading to an increase in volume. This expansion can decrease the density of the air, causing it to rise.
Give one use of thermal expansion in gases?
One use of thermal expansion in gases is in hot air balloons. As the air inside the balloon is heated, it expands and becomes less dense than the surrounding - cooler air, causing the balloon to rise.
