A very simplified explanation is that at greater temperature, the particles move faster.However, this only applies for one specific substance. When comparing different substances, it would be more accurate to say that (roughly speaking, at least) the temperature is proportional to the average kinetic energy per particle, and per degree of freedom.

What is the diffrerence between digital thermometer and mercury thermometer?
Digital thremometer is shows digit and run by electric or cells mercury thermometer is shows mercury up and down. when temperature low and down.
What happens to the particles of a liquid in a can as it cools down after heating?
The particles will have lower kinetic energy, which will slow them down, and the pressure inside the can will decrease as a result.
What makes mercury in a thermometer go up and down?
Change in temperature is what cause the Mercury to expand up (hotter) or shrink down (colder).
When an object increases in temperature do the particles speed up or slow down?
They speed up. Heat is actually molecular motion. Absolute zero (−459.67°F) is the temperature where the particles have no motion at all.
Why do you use mercury in thermometer?
As tempertature rises, the mercury in the thermometer expands, causing it to go up. As temperature decreases, the mercury in the thermometer contracts, causing it to go down on the scale. However, mercury thermometers are very dangerous if it breakes and gets on your skin. so it it reccomended to use an electric thermometer. these thermometers use thermoelectric current to measure temperature. ergo. they are safe if they break cheers <3 -Eli
What do thermometers actually detect about the moving particles that make up a sample of matter?
Thermometers detect the average kinetic energy of the particles in a sample of matter. As the temperature increases, the particles move faster and have higher kinetic energy. This increase in kinetic energy is then measured by the thermometer, allowing us to determine the temperature of the sample.
What are examples of thermal expansion and contraction?
the Mercury in a thermometer expands when heated and contracts when the temperature cools down.
How does an air thermometer work?
An air thermometer has a bubble of liquid inside the tube and when the air inside of the tube heats up or cools down, the air takes up either more or less space inside of the tube, causing the bubble of liquid to either move upwards or downwards, indicating the temperature.
Why does the thermometer go down when cooled?
The cold reduces the temperature in the liquid inside the thermometer bulb. Most substances contract when their temperature drops so the liquid in the bulb occupies less space. this causes the column of liquid outside the bulb to become smaller.
What happenes to particles as the temperature decreases?
As the temperature decreases, kinetic energy decreases, and particles slow down.
What is the diffrerence between digital thermometer and mercury thermometer?
Digital thremometer is shows digit and run by electric or cells mercury thermometer is shows mercury up and down. when temperature low and down.
What do you do before taking an axillary temperature?
Shake down the thermometer before using, if the reading on the thermometer is 94.0º F or above.
Why does the liquid in a thermometer sink down?
This liquid is sometimes colored alcohol but can also be a metallic liquid called mercury. Both mercury and alcohol grow bigger (expand) when heated and smaller (contract) when cooled. Inside the glass tube of a thermometer, the liquid has no place to go but up when the temperature is hot and down when the temperature is cold. Its the process of expansion and contraction
What thermometer measures maximum and minimum pressure?
There is no special name for a maximum-minimum thermometer. It generally consists of two scales one will push a slider up as the temperature increases and the other thermometer pushes a slider down as the temperature goes down. You read it by observing the position of the sliders and then reset it so that the sliders return to the current temperature.
When particles in a solid slow down what does it become?
The temperature is lowered.
Is thermometer a type of manometer?
Not quite; This is what the first source said about how a thermometer works; This liquid is sometimes colored alcohol but can also be a metallic liquid called mercury. Both mercury and alcohol grow bigger when heated and smaller when cooled. Inside the glass tube of a thermometer, the liquid has no place to go but up when the temperature is hot and down when the temperature is cold. In other words, the thermometer goes up or down due to the expansion of the alcohol or mercury due to the heat. After reviewing the second source, you will see that the columns go up and down due to the atmospheric pressure. If it goes up and down due to atmospheric pressure it is a manometer. A manometer does not work if it is not exposed to the atmosphere. A thermometer is sealed off to the outside. This is another reason why a thermometer is different from a manometer.
What makes mercury go up and down a thermometer?
the heat and temperature that causes it to rise and fall.
