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 is the role of liquid in a Galileo thermometer?
The liquid in a Galileo thermometer expands or contracts based on the temperature, causing the glass bulbs with different densities to rise or sink, indicating the temperature.
Why doesn't the liquid in the thermometer move when you turn it upside down?
The liquid in a thermometer does not move when turned upside down because of the properties of the liquid used (usually mercury or alcohol) and the vacuum-sealed tube design of the thermometer. This design prevents the liquid from freely moving when the thermometer is inverted.
What happens to the liquid in the thermometer when it gets colder?
When the liquid in a thermometer gets colder, it contracts and decreases in volume. This causes it to move down the tube of the thermometer, indicating a lower temperature.
What is the liquid in a Galileo thermometer and how does it work?
The liquid in a Galileo thermometer is usually a clear alcohol or water-based solution. The thermometer works based on the principle of buoyancy, where the density of the liquid changes with temperature. As the temperature changes, the liquid expands or contracts, causing the glass spheres with different densities to rise or sink, indicating the temperature.
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.
What is the clear liquid inside a Galileo thermometer?
The clear liquid inside a Galileo thermometer is typically a hydrocarbon-based liquid, such as ethanol or mineral oil. This liquid expands and contracts with temperature changes, causing the glass spheres with different densities to float or sink.
What is the significance of the liquid-filled bulbs in a Galileo thermometer and how do they contribute to its functionality?
The liquid-filled bulbs in a Galileo thermometer are different densities of liquid that rise or fall with temperature changes. This causes the bulbs to float or sink, indicating the temperature. The bulbs help the thermometer accurately measure temperature by showing the temperature through the movement of the bulbs.
What is inside a Galileo thermometer and how does it work?
A Galileo thermometer contains liquid-filled glass bulbs of different densities. As the temperature changes, the bulbs rise or sink in the liquid, indicating the temperature. This works because the density of the liquid changes with temperature, causing the bulbs to move accordingly.
What causes liquid in thermometer to travel up and down in tube?
Heat causes Mercury in the thermometer to expand, where as when it is cooled, it contracts.
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 is the function of the constriction on a thermometer?
The constriction on a thermometer helps to trap the liquid (typically mercury or alcohol) within the bulb when the thermometer is tilted or turned upside down. This ensures that the thermometer gives accurate readings by keeping the liquid contained within the measuring portion of the instrument.
Why should liquid waste not be dumped into the sink?
Liquid wastes should not be dumped down a sink because they can cause back-up. This liquid waste could also break pipes.
