The Mercury in the bulb at the bottom of the thermometer expands or contracts depending on the amount of heat (the temperature). The narrow calibrated tube that you read the temperature on acts to amplify this effect. The calibration is usually either in Fahrenheit or Celsius.

You go up the notes playing each one individually but holding them all down until the time it needs to take is over
Freddie Mercury can perform up to four octaves.

They move it up and down, causing the air to create lift and thrust. Before they move their wings up, they adjust the wings to make it go down a little, then when move their wings down, they adjust them to make go up which creates lift.
Depending on Atmospheric Pressure
the heat and temperature that causes it to rise and fall.
Digital thremometer is shows digit and run by electric or cells mercury thermometer is shows mercury up and down. when temperature low and down.
Change in temperature is what cause the Mercury to expand up (hotter) or shrink down (colder).
There is a kink put in the tube which carries the mercury up the thermometer, that is why it needs to be shaken to send it back to the bulb
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

Heat causes Mercury in the thermometer to expand, where as when it is cooled, it contracts.
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.
Expansion (of metals) with increasing temp.
If you have an old thermometer that has mercury, then the shaking makes all of the mercury flow to the bottom of the thermometer. Then, you can get a better reading. The current digital ones work differently. Thermometers used for taking people temperatures are a special kind that go up with heat but don't go down with cold. So you have to shake a thermometer before taking your temperature to make the reading go down below your own temperature. Then the thermometer can go up again to read your temperature.
the red part in a thermometer is mercury.
