we already know that by expension the kinetic energy of molecules decreases hence causes a little decrease in temperature but when suuden expension takes place then fast moving molecules takes energy from that area and rapidly decrases temperature.
Now let's prove it mathematically we know that
PV=nRT
when expension occurs pressure decreases more than volume increses hence PV product decreases on the right hand R & n are same hence temperature decreases.

Where does thermal expansion and contraction occur?
Thermal expansion and contraction occur in materials when they are exposed to changes in temperature. This can happen in solids, liquids, and gases, leading to changes in volume, length, or density of the material. It is a common phenomenon experienced in everyday objects and structures.
What is the rapid expansion of matter accompianied by heat and light?
The rapid expansion of matter accompanied by heat and light is known as an explosion. This process typically involves a sudden release of energy that causes matter to be propelled outwards, generating heat and light in the process. Explosions can occur in various natural and man-made situations, such as volcanic eruptions, supernovae, or bomb detonations.
In a refrigeration cycle the flow of refrigerant is controlled by?
The flow of refrigerant in a refrigeration cycle is controlled by devices such as expansion valves and metering devices. These components regulate the amount of refrigerant entering the evaporator and maintain the proper pressure and temperature for the cooling process to occur efficiently.
What is thermal expansion and contraction of matter?
Thermal expansion is the increase in size of a material when its temperature increases, while thermal contraction is the decrease in size when the temperature decreases. This phenomenon occurs because heating causes atoms to vibrate more and move further apart, leading to expansion, while cooling causes atoms to vibrate less and come closer together, leading to contraction.
A circular flow of warmer fluid and cooler fluid is called a?
A convection current, however, this can also occur with gases.
Where does gases have cooled?
Gases cool down when their temperature decreases, causing their particles to slow down and lose energy. This cooling process can occur naturally in the atmosphere, as in the case of air cooling at higher altitudes, or artificially through methods like refrigeration or expansion cooling.
What are explosions made off?
Explosions are typically made of a rapid release of energy in the form of heat, light, sound, and pressure. They occur when a sudden chemical reaction or physical force causes a rapid expansion of gases. The specific materials involved can vary greatly depending on the type of explosion.
Where does thermal expansion and contraction occur?
Thermal expansion and contraction occur in materials when they are exposed to changes in temperature. This can happen in solids, liquids, and gases, leading to changes in volume, length, or density of the material. It is a common phenomenon experienced in everyday objects and structures.
What will happen if a sudden expansion is provided immediately after the throat of a venturimeter?
If a sudden expansion is provided immediately after the throat of a venturi meter, the flow velocity will decrease abruptly due to the sudden increase in cross-sectional area. This can lead to recirculation zones, pressure recovery losses, and inaccurate flow rate measurements due to disturbances in the flow profile. It is important to ensure a gradual and controlled expansion to maintain accurate measurements.
How do fire explosions happen?
Fire explosions happen when a flammable substance is suddenly exposed to a source of ignition, causing a rapid release of energy in the form of heat, light, and pressure. If the conditions are right, such as when flammable gases mix with air in the correct proportions, an explosion can occur. This sudden release of energy can result in a rapid expansion of gases, causing a shock wave and potentially leading to a fireball.
Where does the exchange of gases occur in the plant?
During the stage of photosynthesis, the exchange of gases occur in the leaves.
What regulatory mechanisms would occur in response to a sudden increase in blood pressure?
Sudden vasodilation
What are three different types of accidents or sudden illness that may occur in a social care?
accident or sudden illnesses that may occur in a social care setting
What are three different types of accidents or sudden illness that may occur in a social care settings?
accident or sudden illnesses that may occur in a social care setting
What energy conversions occur in a car engine?
Chemical energy in the petrol is converted to heat energy by igniting it with air. This causes an expansion of the gases which creates kinetic enrgy by moving pistons which connect to a crankshaft.
Describe sudden illness and accidents that may occur in health and social care?
Heart attacks are some of the sudden illness and accidents that may occur in health and social care.
Goosebumps occur due to?
they occur because of excreation of papillae especially from cold,fear,or a sudden feeling of excitnment.
