As the applied temperature increases, it expands in the glass tube of the thermometer. This expansion is correlated to the graduations, which we read directly.

Another effect, not relevant to the function of the thermometer, is that when the liquid expands, there is a corresponding decrease in its density.

The 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.

The particles of the liquid inside a thermomater begin to move faster and farther apart when the temperature increases

Most materials expand with the temperature increases. In this case, the liquid in the thermometer expands faster than the glass that holds it.

A thermometer has mercury inside it and if the temperature increases, the mercury expands and due to it we come to know that the temperature is increasing. A temperature sensor is a device which is used to sense the temperature. A thermometer consists of a temperature sensor at the top and the mercury meter below it.

A thermometer is for telling how the temperature is out side or inside.

The liquid in thermometers expands when temperature increases (and contracts when temperature decreases). When it expands, the only place for it to expand 'to' is up the thermometer (into the empty space above it).

A thermometer measures temperature by using the liquid inside of the thermometer. It measures temperature by Celsius and Fahrenheit.

If you increase the temperature of a fluid, the pressure in the container increases.

Gas expands as its temperature increases and contracts as its temperature decreases. That's why balloons often pop when held close to a heat source; the gas inside them expands and breaks the balloon.

Because that will mess with the temperature reading on the thermometer. And it would be dangerous if the thermometer is broken as there are dangerous chemicals (i.e.mercury) inside.

No. The tube inside a thermometer is vacuum. If there was a gas inside, the pressure changes due to temperature changes would cause the liquid inside to expand/contract unevenly.

Inside the tank as it is for you to see the water temperature.

A thermometer is used for meat cooking to make certain it has cooked to the right temperature inside.

it depends on the gas it might pop the thing if the balloon doesn't melt first

A clinical thermometer is used to measure the temperature inside your body. It need only measure between 95 and 105 Fahrenheit. A lab thermometer measure a much wider range of temperature.

A hot air balloon is a practical application of Charles Law. Another practical application is a plunger turkey thermometer. As the temperature inside the turkey increases the volume of air increases and eventually pushes out the plunger.

The truth is there is no water thermometer in the world.If the temperature is high the water inside the capillary will start to boil and the thermometer will eventually burst

If the temperature increases, then the volume of the gases cannot stay the same. The pressure will keep building until it overcomes the integrity of the container its contained in and causes an explosion.

Pressure increases in proportion to the rise in temperature. See Boyle's Law, Charles' Law & Ideal Gas Law

The liquid inside the thermometer "contracts" when it is placed into something cold. This means that it decreases in volume and increases in density. This is the reason that the thermometer can measure heat: the volume of the liquid inside the thermometer changes as a function of heat, and the amount of liquid in the "tube" of the thermometer changes as a function of volume. Because of this relationship, the level of the liquid in the tube of the thermometer changes as a function of heat.

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.

the difference is that precipitation only happens outdoors and temperature happens both inside and outside! here is a little chart for you of differences: precipitation temperature ____________ ___________ measured using measured using rain gauge thermometer rain,snow,hail,sleet Fahrenheit and Celsius

A protostar is created before the star which has Gravitational energy which is then converted into heat energy which increases the temperature.
