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 happed to the particles inside of a thermometer when the temperature goes down?
When the temperature goes down, the particles inside a thermometer lose kinetic energy and move slower. This causes them to contract and move closer together, leading to a decrease in volume. This change in volume is what allows the thermometer to measure lower temperatures.
What happens to the thermometer when it enters in cold water?
When a thermometer enters cold water, the temperature reading on the thermometer will decrease as the thermometer adjusts to the temperature of the water. The liquid inside the thermometer will contract and move down the scale, indicating the lower temperature of the cold water.
Why does the thermometer go down when the temp gets cold?
A thermometer measures temperature based on the expansion or contraction of the liquid or metal inside it. When it gets cold, the molecules inside the thermometer contract, causing the liquid or metal to shrink, which in turn results in the reading on the thermometer going down.
Ho does a thermometer measure temperature?
A thermometer measures temperature by using a substance that expands or contracts with temperature changes, such as mercury or alcohol. As the substance heats up or cools down, it moves along a scale marked on the thermometer, providing a reading of the temperature.
How does a thermometer work upside down?
A thermometer works the same way whether it is upright or upside down. The liquid inside the thermometer expands and contracts based on the surrounding temperature, causing the level of the liquid to rise and fall on the scale. This movement indicates the temperature being measured.

What do thermometers actually detect about the moving particles that make up a sample of matter?
Thermometers actually detect the temperature of moving particles in motion. Both mercury and alcohol (substances in thermometers) 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.
How is expansion used in a thermometer?
Expansion is used in a thermometer to measure temperature changes. As temperature increases, the liquid (like mercury or alcohol) inside the thermometer expands and rises up the tube, indicating a higher temperature. Conversely, when temperature decreases, the liquid contracts and moves down the tube, showing a lower temperature.
How does clinical thermometer work?
A clinical thermometer works by measuring body temperature through the expansion or contraction of a temperature-sensitive liquid, such as mercury or alcohol, inside a sealed glass tube. As body temperature rises, the liquid in the thermometer expands and moves up the tube, indicating the temperature. Conversely, when body temperature decreases, the liquid contracts and moves down the tube.
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.
How does a glass stem thermometer measure temperature?
A glass stem thermometer measures temperature by using the principle of thermal expansion. The liquid inside the glass stem expands or contracts with temperature changes, causing the level of the liquid to move up or down the scale. This movement indicates the temperature.
What is the purpose of using a bulb thermometer?
A bulb thermometer is used to measure temperature by relying on the expansion and contraction of a liquid (typically mercury or colored alcohol) inside a glass tube. When the temperature changes, the liquid expands or contracts, moving up or down the tube and indicating the temperature on a scale.
What are examples of thermal expansion and contraction?
the Mercury in a thermometer expands when heated and contracts when the temperature cools down.
