Why does the liquid level rise in a theremometer when the temperature is higher?

When the liquid is heated (by the environment), the particles in the liquid have more energy, and start moving around more, which causes the liquid to expand and take up more room.
Conversely, in cold temperatures, the particles do not have as much energy, and do not move as much, so the liquid contracts.

∙ 14y agoBecause that liquid in thermometer is actually a kind of metal called Mercury (atomic symbol Hg). And like all metals it expand when heated.
Hot water contains heat.
---------------------------------------------
Because the liquid in the thermometer expands when it is warmed. As it expand it takes up more space and therefore rises up the measuring tube of the thermometer.There is liquid in some thermometer but, most have chemicals in it!!!!!!!!!!!

∙ 11y agoThe liquid is usually mercury or an alcohol-based liquid. The liquid rises because its volume increases as it is heated more than the glass that surrounds it, and the only way the liquid can go as it expands is upward.

∙ 10y agoThe liquid expands as its temperature increases. This is the same as saying that it occupies more space as temperature increases. Therefore it 'uses up' more of the space inside the thermometer as the temperature increases.

What is the liquid in a carpenter's bubble level and at what temperature will it freeze?
bobo ka,try to answer it youre self
When can liquid water remain above 100 degrees Celsius?
Water can remain liquid at a temperature above 100 degrees, C., when the pressure on it is greater than the pressure found at average sea level.
What elements are liquid at room temperature?
The scientific definition of room temperature, also known as standard temperature and pressure (STP), is 68°F (20°C) at one atmosphere (sea level).By this definition, bromine and mercury are the only two elements that are liquid at room temperature.Three other elements -- cesium, gallium and rubidium -- become liquid near this mark. Cesium, for example, becomes liquid at 82° (28°C).It's also believed that francium would be liquid at or just above room temperature, but this highly-unstable radioactive element has yet to be manufactured in a quantity which would confirm this.
How does the height above sea level affects the temperature?
I learned the answer to this in science this year, so don't worry, it is accurate: The higher above sea level/elevation you are, the colder the temperature becomes. The reason for this is because there are air molecules in the air bump closer together when you are lower above sea level- that creates warm weather. The higher above sea level you go, (for example, the tops of mountains,) the more separated and spaced out the molecules become, which causes cold weather. This is the ACCURATE answer to how elevation affects temperature.
Are the bases of convective clouds generally higher during the day or the night?
The level of dew point temperature at which the clouds condense rises during the day.Hence the bases of the clouds will be higher at day time.
Describe how a thermometer uses the thermal expansion of a material to measure temperature?
A thermometer is a device that is used to gauge temperature. Mercury style thermometers used the elemental liquid in a tube of measured diameter and height. The higher the temperature, the higher the observed mercury level is. Thus, the height of the mercury uses marking to indicate which air temperature corresponds to the given height of its liquid expansion.
Is it possible for a liquid to boil at a temperature other than its normal boiling point?
yes it is. The boiling point of a liquid is affected by the atmospheric pressure, so it is higher at sea level than it is at high altitude. Also depends on the purity of liquid
How is temperature related to the solubility of a solid solute Why?
At the molecular level, temperature is inversely proportional to solubility. As the temperature of a liquid increases, the solubility of gases in that liquid decreases.
How does a liquid thermometer show that you have a fever?
That type of thermometer has mercury in it, which is very heat sensitive. When used for taking a temperature, the heat from the body causes the mercury to rise. The amount the level of the mercury rises is determined by the body's temperature; the higher the temp, the higher the mercury rises.
What is ammonia a liquid or a gas?
At STP (standard temperature and pressure) it is a gas. It can be made to be a liquid or gas by adjusting the temperature and pressure around it, but at room temperature and one atmosphere of pressure (sea level) it is a gas.
What can change the boiling point of water?
the height you are away from see level. as you get higher, the temperature gets higher.
What happens to a liquid-vapor system at equilibrium if the temperature decreases?
If the temperature of a liquid decreases, so does the vapor pressure. Clothes dry faster in a warm or hot clothes dryer than they do when hung up in a cool house. The vapor pressure of water is higher when it is warmer in the clothes dryer. Clothes dry faster in the sunshine than in the shade. Sunshine is warmer.
What temperature does methanol boil at high altitude?
How high is high? The boiling temperature depends on the pressure of the atmosphere above the liquid. The higher you go the lower is the atmospheric pressure, and so the boiling temperature. Methanol boils at 64.7°C (148.4°F) at 760mmHg, about sea level.
What is it when a persons hypothalamic thermostat is set to a higher level and the actual body temperature below that level?
shiver
The water boils at what temperature?
100 Celsius or 212 Fahrenheit at sea level. As you go higher, the temperature drops as less force is needed to counter act air pressure. At 5000 feet above sea level (1524 meters) the temperatures are 95 C and 203 F.
Is wax a solid liquid or gas?
That depends upon temperature and pressure. At room temperature and sea level pressures, most waxes are solid or if you melt it it turns in to a liquid but if you put it at 100 degrees it turns in to gas.
What is the name for the temperature when liquid turns into a gas?
It's called the boiling point. It is the temp where the vapor pressure of the "liquid" is equal to the air pressure around (above) it. This is when the liquid [water] reaches 100 degrees Cecilius [at sea level].
