What else can I help you with?
Why metal expands when heated?
Molecules move back and forth faster and faster causing expansion
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 is liquid rising in a thermometer as temperature increases is an example of?
This is an example of thermal expansion, where the liquid in the thermometer expands as it is heated, causing it to rise within the tube.
What are the three physical properties that vary with temperature?
Three physical properties that vary with temperature are volume, density, and thermal expansion coefficient. As temperature increases, volume generally expands, which can lead to a decrease in density. The thermal expansion coefficient quantifies how much a material expands or contracts with changes in temperature.
What is compression and expansion of rock is called?
Compression of rock is when external forces push or squeeze the rock, causing it to decrease in volume. Expansion, on the other hand, is when the rock expands or swells due to changes in temperature or pressure.
What is unique about the expansion of water?
that water expands when it gets cooler , other forms of matter expands when it gets hotter.
Which term describes a period in which the power of the government expands?
Expansion
What is global expansion?
Global expansion is when a business opens and expands opportunities for that business to increase sales etc.
What is an ethernet switch expansion slot?
expands the amount of Ethernet cables you can have.
Matter expands when its gets hotter and contracts when it cool?
The explanation of Thermal Expansion.
What is the difference between sims expansion packs and stuff packs?
expansion pack expands the game. stuff packs give you items
What is meant by the cofficient of linear and superficial expansion?
The coefficient of linear expansion measures how much a material expands in length when heated, while the coefficient of superficial expansion measures how much a material expands in area when heated. Both coefficients are used to quantify how materials respond to changes in temperature.
What happen to the mercury in a thermometer when the temperature increase?
When the temperature increases, the mercury in a thermometer expands and rises up the column because the volume of the liquid increases with temperature. This expansion is linear and is used to indicate the rise in temperature on the thermometer scale.
How does the rotary thermometer work?
A rotary thermometer works by using a metal coil that expands and contracts with temperature changes. As the coil expands or contracts, it rotates a pointer on a scale or dial to indicate the temperature. This movement is due to the principle of thermal expansion, where materials expand or contract when heated or cooled.
What is a expansion tank on a car?
As the engine coolant heats up, the coolant expands, so the coolant needs a reservoir or expansion tank to flow in and out of as needed.
Why metal expands when heated?
Molecules move back and forth faster and faster causing expansion
How does a thermomerator measure temperature?
that depends on what type of thermometer. The tube thermometer, the kind with a glass tube with a red liquid in it, uses a small amount of mercury in a very small tube. When the mercury is heated, it expands, pushing further up the tube, as it cools it contracts, going down the tube. A dial thermometer also works on expansion and contraction, but with a coil instead of mercury.
