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.
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 a thermometer made out of?
a liquid thermometer is made with a glass "shell" and ussually have murcur inside them that dilates when it gets hotter and rises and contracts when its colder and lowers- this has been made by a 12 year old boy
What happens when the density of a fluid gets hotter?
When the density of a fluid gets hotter, it usually decreases. This is because as the fluid gets hotter, its molecules gain energy and move farther apart, causing the fluid to expand. This expansion leads to a decrease in density.
How does the liquid in a thermometer move up and down?
When the liquid in the thermometer gets warmer it expands. This means its volume increases. The only place for the extra volume to go is up the tube, so the level of liquid rises. When the liquid gets colder it contracts (reduces in volume) so it moves back down the tube. See http://www.energyquest.ca.gov/how_it_works/thermometer.html
Why does the liquid in thermometer go up the tube when it gets hotter?
Heat causes mercury in the thermometer to expand, where as when it is cooled, it contracts.
How does the temperature increase on a thermometer?
Temperature increase on a thermometer is typically indicated by the expansion of the liquid or mercury within the tube. As the temperature rises, the molecules in the liquid move faster, causing it to expand and rise up the scale on the thermometer. This expansion is calibrated to reflect the corresponding increase in temperature.
What happened to the temperature of a liquid as it evaporates?
It gets hotter
How a liquid thermometer works using thermal expansions?
In the right conditions and circumstances all liquids will expand
What causes the liquid to move in a thermometer?
When the liquid in the thermometer gets warmer it expands.
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 happen to the liquid in a thermometer when it gets warm?
When a thermometer is exposed to warmth, the liquid inside it expands and rises up the tube. This is because heat causes the molecules in the liquid to move faster, taking up more space and causing the volume to increase. The expansion of the liquid is used to measure 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.
Why mercury is used in thermometer for indication?
Because it is just a standardised and easy way of making thermometers. You could use any substance, the pricible is the same: A substance will expand the hotter it gets. Mercury just expands a lot more than most elements and so is easier to make a thermometer.

Why is liquid used in thermometer?
Liquid is used in a thermometer because it expands and contracts uniformly with changes in temperature, allowing for accurate temperature measurements. The liquid inside the thermometer expands and rises in the capillary tube as it gets warmer, providing a visible indication of temperature.
