What change takes place in the liquid inside a thermometer when the thermometer is placed into something cold?
When a thermometer is placed into something cold, the liquid inside contracts and decreases in volume. This causes the liquid level to decrease, indicating a lower temperature on the scale of the thermometer.
What is thermometric substance?
These are materials used in thermometer whoses property varies with temperature
How does a thermometer indicate the temperature of an object?
A thermometer measures temperature by using a material that expands or contracts with changes in temperature. This material is usually mercury or alcohol. As the temperature of the object being measured changes, the material in the thermometer expands or contracts, causing the level to rise or fall on a scale, indicating the temperature.
What is the purpose of Mercury in a Thermometer?
Mercury in a thermometer is used because it has a high coefficient of expansion, meaning it expands and contracts in response to temperature changes. This property allows for accurate measurement of temperature as the mercury level rises and falls inside the thermometer. Additionally, mercury has a wide temperature range in which it remains a liquid, making it suitable for measuring a broad range of temperatures.
What liquid expands instead of contracts when frozen?
Water is a liquid that expands when it freezes. This is due to the unique structure of water molecules, causing them to form a crystalline lattice when frozen, which takes up more space than liquid water.
What is the working of the thermometer?
capillarity rise.heating expands mercury whereas cooling contracts mercury
Which liquids expand on cooling?
I think that only water expands when it freezes everything else contracts
What is the thermometric property used in a mercury thermometer?
Not just a property of liquid but of all matter. All matter expands when heated and contracts when cooled, in thermometers the liquid, usually an alcohol, expands when heated lengthening the little line.
Which metal expands on cooling and contracts on heating?
Bizmuth is a heavy metal that expands on cooling and contracts on heating. it is used for making lead free ammunition, especially for shotgun rounds and airgun pellets as it is considered non-toxic. It is also used in the glass making industry for making 'float' glass sheets.
Does a thermometer's mercurry expand contract on condenses?
it expands and contracts when the temperature drops, the mercury contracts...when the temperature increases, the mercury expands
What state of matter expands with cold and contracts with heat?
Well, solids. For example, when you heat up metal is expands and when you freeze it, it contracts
Which organ of the respiratory system expands and contracts automatically to force air into and out of the lungs?
The diaphragm expands and contracts automatically, forcing air into and out of the lungs.
What property of mercury make it good material for thermometer?
It's a liquid over a fair range of temperatures and it expands and contracts noticeably with small changes in temperature.
What are examples of thermal expansion and contraction?
the Mercury in a thermometer expands when heated and contracts when the temperature cools down.
Why does water expand on heating?
water expands on heating and contracts on cooling because when water is heated the molecules are closely packed and they overflow but when cooled they are loosely packed therefore they dont overflow. it is as simple as that.
Matter expands or contracts to fill the space available?
Matter generally expands when heated and contracts when cooled. This is due to the changes in the kinetic energy of the particles within the matter. The expansion or contraction allows matter to adjust its volume to the space available.
What expands and contracts?
pretty much everything.....depends on the heat
