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.
When the temperature increases, the particles of the liquid inside a thermometer also expand due to thermal expansion, causing the liquid to rise in the narrow tube of the thermometer. This increase in volume of the liquid is what is typically measured as an increase in temperature on the thermometer scale.
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.
A constant volume thermometer measures temperature by keeping the volume of the gas inside the thermometer constant. As temperature changes, the pressure of the gas inside the thermometer also changes, which can be correlated to the temperature. This type of thermometer is commonly used in laboratories and for precision measurements.
Temperature affects a thermometer by causing the liquid or material inside to expand or contract, leading to a change in volume. This change in volume is measured by the scale on the thermometer, so as temperature increases or decreases, the level of the liquid or material inside the thermometer will rise or fall accordingly.
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.

Yes, particles in the air have more average kinetic energy compared to particles in the mercury. This is because the air temperature is higher than the temperature of the mercury inside the thermometer, so the air particles are moving faster on average.

Thermal expansion of the fluid inside the thermometer.
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.
The red fluid used inside a thermometer is typically colored alcohol or mercury that expands and contracts with changes in temperature to indicate the temperature reading.
When the temperature goes up, the mercury or alcohol inside the thermometer expands, causing the level to rise. This increase in volume is directly correlated with the increase in temperature, allowing the thermometer to indicate the higher temperature.
The keyword "what" in a Galileo thermometer is used to indicate the temperature at which the liquid-filled bulbs inside the thermometer are floating.
