When a substance undergoes thermal expansion what happens to the particles?
As you might expect from the term "expansion", they get farther apart from each other - at least on average. They also tend to gain more vibrational energy, rotate faster (when able to) and move around faster in general.
What happen to the liquid in a thermometer when it gets warm?
The liquid expand from heat. We use these expansion to indicate temperature. Common thermometer liquid is Mercury and alcohol.
What happens when magnesium bicarbonate is heated?
if heated in air, it undergoes hudrolysis. on strong heating it forms MgO.
Which has higher density cold steel or hot steel?
When steel gets hot, it gets slightly larger due to thermal expansion. Since the mass stays the same, and density = mass/volume, it gets (very, very slightly) less dense. So cold steel is more dense than hot steel.
What is the process called when particles in a metal lid expand under hot water?
This is a misconception. Particles do not expand, When they get hot they move further apart. This means that the object (the lid) gets bigger. It's just called expansion.
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?
when air gets cooled by water in USA on christmas evening
What is adiabatic heating and cooling?
Adiabatic cooling happens as air mass expands with increasing elevation (because density of gases decreases farther into the atmosphere). As elevation increases, the air gets cooler because energy is drawn from the surroundings. Less dense air traps less heat resulting in this net cooling called adiabatic cooling. It occurs at an average of 6 degrees Celsius per 1000 meters, but it can vary.
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.
