Because 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!!!!!!!!!!!

The liquid in the thermometer must steady its temperature first before measuring the temperature of the warm water as the warm water is hotter.

The liquid volume of an object is the amount of liquid (like water or oil) that the object (like a glass) can hold when completely filled.

water doesnt undergo significant thermal expansion. alcohol expands more when it's heated

The first thermometer was a tube filled with water and air.

Liquid glass is Sodium Silicate also known as water glass.

Water is an unusual liquid in that it expands as it freezes. This can cause it to break a glass container as the water content freezes.

no water is not present in a glass , glass itself is known as liquid

Because the ocean is filled with liquid water.

if you put water in a thermometer and it gets hot the water expands and might and burst and when it gets to cold it freezes

Charles WingerThe Thermometer was invented by Galileo Galilei in 1593. His thermometer consisted of water in a glass bulb; the water moved up and down the bulb as the temperature changed.

The liquid that condenses on glass when you breathe on it is water. The water is a condensate, and the cooler glass causes water in air we exhale to cool and condense.

The cup is solid, but the water remains liquid unless you freeze it into ice.

For a thermometer we need a liquid which properly expands and contracts according to the temprature. Water doesn't has that property, i.e. the expansion in water is to small to be used as a liquid in theremometer.

A condensate is a liquid that is formed from the process of condensation. An example of a condensate is the water that forms on the outside of a glass filled with water and ice on a very hot day.

Yes. You can do this by right-clicking a glass bottle in water or a water-filled cauldron.

yes, a mineral definitely can be a liquid. think about water, and glass. glass is a mineral, but when melted becomes a liquid.

because water freezes at 0 degrees Celsius

If there is a cold liquid in the glass, water vapor in the air around the glass will be cooled and drops of liquid water will condense.

The water would frequently freeze in colder regions. Water also has the unique property of expanding as it cools near its freezing point, which would result in inaccurate measurements.

The question must be asked carefully. If the thermometer is in water ice and there is no liquid water, and there is one atmosphere of pressure, the thermometer can read anything from the freezing point of water and lower, depending on the range of the thermometer. If the thermometer is in a stable mix of water and ice, it will read the freezing point of water.

For the basic principle, it can be ignored, since the liquid expands more than the glass.For exact calculations, the expansion of glass must also be taken into account. In practice, however, you'll want to calibrate the thermometer with known temperatures (for example, the temperatures of freezing and boiling water) - in which case such calculations are both unnecessary and useless.

there are little glass bubbles filled with a colored liquid, usually food coloring and water. each little bubble has a weight attached with the temperature engraved into it. all these bubbles are about the same density as water, and as the temperature changes, the bubbles float and sink. the bubble that sinks to the bottom is the current temperature. The temperature-dependent property that a Galileo thermometer makes use OS is the density of liquid. The thermometer contains several sets of spheres and tags. Each of the sets has a specific density. Since the density of the liquid in the thermometer varies with temperature, spheres with densities lower float while the others sink at a certain temperature. Thus, the tag on the lowest floating sphere tells us the temperature.

3 - solid, liquid and gas (water vapour in the air above the liquid in the glass)

The air outside the glass has water vapor in it. This is cooled and condenses on the glass.
