An example of heating and cooling a liquid would be a thermometer. When the liquid in the thermometer is heated, it causes it to move a bit further apart. The movement up the temperature is a result of this.
How does a thermometer work in physics?
The principle of expanding with temperature is worked on by a thermometer. Mercury rises when a lamp is immersed in a solution. The temperature scale is used to study the increase in mercury.
How does a thermometer work chemistry?
Material that expands or contracts when heated or cooled are used to measure temperature. Mercury or alcohol thermometers have a liquid that expands when heated and contracts when cooled, so the column can be shortened or lengthened as the temperature of the liquid changes.
How does a thermometer work simple answer?
The material conducts heat energy to the mercury when it is touched by the mercury thermometer. As mercury becomes a liquid, it starts to rise up the tube. The reading of the temperature can be taken at the place where the mercury stops.
How is a thermometer used short answer?
A thermometer is used to measure the temperature. It is possible to measure the temperature of food, water, or air. The temperature can be measured in Celsius, Fahrenheit, and kelvin. The metric system has two scales: the Celsius scale and the metric system.
What is temperature and how does it work?
The temperature is the measure of hotness or coldness expressed on a number of scales. The temperature shows the direction in which heat energy will flow from one body to another.
How does a thermometer work kinetic energy?
There is a transfer of thermal energy between the air and the wall of the thermometer when there is an air molecule colliding with it. This causes the molecule in the liquid to move in a different direction.
How does a mercury thermometer work physics?
A mercury thermometer has a glass tube filled with mercury and a scale on it. The mercury expands and contracts when the temperature goes up. It is possible to determine body, liquid, and vapor temperature with a mercury thermometer.
What is temperature in physics in simple words?
The temperature is the measure of hotness or coldness expressed on a number of scales. The temperature is the direction in which heat energy will spontaneously flow from one body to another.
