When a substance undergoes thermal expansion what happens to the particles?
When a substance undergoes thermal expansion, the particles within the substance gain kinetic energy. This increase in kinetic energy causes the particles to move more vigorously, leading to increased spacing between the particles. As a result, the substance expands in size.
Why does the substance in the thermometer go up when it gets hot?
The substance inside a thermometer expands when it gets hot due to increased kinetic energy of its molecules. This expansion causes the liquid to rise up the column, indicating a higher temperature reading.
What gets oxidized in an electrolytic cell made with nickel and copper electrodes?
Cu(s)
What happens when anhydrous copper sulphate gets wet?
When anhydrous copper sulfate (CuSO4) gets wet, it absorbs water and undergoes a chemical reaction to form hydrated copper sulfate (CuSO4·5H2O), which is commonly known as blue vitriol. This results in a color change from white to blue as the compound gains water molecules and becomes hydrated.
What does metal do when heated?
When metal is heated, its atoms absorb energy and vibrate more rapidly, causing the metal to expand. This expansion can cause the metal to change shape or even melt if the temperature is high enough. Additionally, heating metal can change its physical properties, such as conductivity and hardness.
What is the role of compressor in ice making plant?
If you compress a gas, it gets hotter through a process called adiabatic heating. It gets even hotter because the compressor is not a perfect machine and will add heat to it. It you take the compressed gas and let it cool to ambient temperature by passing the hot compressed gas through a radiator and then let it return to ambient pressure you will get adiabatic cooling. If this now cooled gas was compressed again and cooled again you could make it colder and colder. A process like this is used to make liquid oxygen. Special refrigerant gasses are usually used so that when they are compressed they become a hot liquid that is then cooled. This is then allowed to evaporate through a small hole. Not only does this mean you get adiabatic cooling but there is more energy absorbed to enable the change of state from liquid to gas, or latent heat of evaporation.
How bike engine gets cooled?
race bikes are cooled by air air circulation but in sports bike they are cooled by oil coolant
What happens when air pressure is cooled?
When the air is cooled it mostly rains
When air is gets cold?
when air is cooled it sucks
When air is cooled what happens?
Uhm, it gets colder of course....
Why does the Eiffel tower get taller in summer?
The Eiffel Tower gets bigger in the summer becaus of Thermal Expansion. It gets 15cm taller.
What is indirect evaporation?
Indirect evaporation refers to a cooling process where water is evaporated into the airstream without direct contact between the water and the air. This method is commonly used in air conditioning systems to reduce the temperature of the air passing over a heat exchanger.
What is adiabatic heating and cooling?
Adiabatic heating occurs when air descends and is compressed, causing its temperature to rise without heat being added or removed. Adiabatic cooling happens when air rises and expands, resulting in a decrease in temperature without heat being added or removed. Both processes are responsible for changes in temperature in the Earth's atmosphere.
Why does a hot air balloon rise when it is heated and sink wen it is cooled?
If it is cooled its gets extremely cold from the helium,and when the heat is in the balloon it keeps it warm when its in the helium
When a substance gets bigger because of heat you call it?
expansion.
When Copper gets longer from heat - what is this called?
thermal expansion
What is the result when benzene gets ignited and undergoes the Baeyer's test?
Benzene is flammable so when it is ignited fire will be produced and then black soot will appear. When benzene undergoes Baeyer's test, the process is slow but it will turn brown.
