How do liquid-filled thermometers measure temperature based on thermal expansion?
Look at an ordinary thermometer. You will see the mercury or achohol inside, and you will see regular degree markings along the thermometer. As the mercury or alchohol changes temperature, it expands and contracts.
How does a thermometer indicate the temperature of an object?
The heat of the object heats the metal tip and heats the liquid inside (usually mercury) until it expands, thereby filling the thermometer. Various tests are performed to determine at what length is what temperature.
How does a thermometer work as a tool to measure thermal energy?
The first units of heat (Fahrenheit and Celsius) were created based on the thermometer. Not the other way around. That way, the thermometer would always be accurate. The thermometer works by putting a specific amount of mercury (a strange metallic substance) inside a tube of a specific volume. When the thermometer is heated, the mercury expands, pushing itself up the tube. The mark that it reaches is measured and recorded in degrees.
Why does liquid inside a thermometer rise as the temperature s increase?
Most materials expand with the temperature increases. In this case, the liquid in the thermometer expands faster than the glass that holds it.
What liquid is inside thermometers?
If the liquid is silver, it is liquid mercury (Hg). If the liquid is red, it is coloured ethyl alcohol (C2H5OH).
How mercury rises in thermometer by rising temp?
The mercury in the thermometer's tube expands and contracts due to the surrounding temperature. As the mercury is inside a narrow tube, it can only expand upwards, and contract downwards.
How does a bulb thermometer work?
The bulb is the ball where most of the liquid is concentrated.

What is the liquid in the ball of the thermometer?
the liguid inside the thermometer is Mercury.
What is the liquid in thermometer's called?
Mercury the liquid inside thermometer is mercury.. but it is called thermometric liquid.
Why do you like Mercury?
i like mercury because it is inside a thermometer

What is the clear liquid inside a Galileo thermometer?
mercury
How do you get connected to the mercury?
When thermometer is kept inside the mouth
What is the silver liquid inside of a thermometer called?
Mercury
What change takes place in the liquid inside a thermometer when the thermometer is placed into something cold?
The liquid in thermometers contracts when placed in something cold (and expands when placed in something hot.)
Why the Mercury-in-glass thermometer first descends and then rise when put in flame?
When placed in a flame, the glass bulb expands rapidly. This increases the volume of the bulb and so the column descends. However, the glass then conducts the heat to the mercury so that it undergoes thermal expansion and the column rises.
