When thermal energy is added to a substance, the molecular movement increases. Because they are moving around, they need more space, which is provided by occupying a larger volume.

What is the principle of Mercury?
Mercury thermometers are based on the fact that materials (in this case, the liquid mercury) expand when heated.Mercury thermometers are based on the fact that materials (in this case, the liquid mercury) expand when heated.Mercury thermometers are based on the fact that materials (in this case, the liquid mercury) expand when heated.Mercury thermometers are based on the fact that materials (in this case, the liquid mercury) expand when heated.
What liquid expands when heated?
All liquids expand when heated. e.g. Mercury in a thermometer. One exception may be water when heated form 0 to 4 degrees Celsius.
A sample of liquid mercury is heated from 20 and degC to 40 and degC. Which measurement of the sample will increase during this process?
As the liquid mercury is heated from 20°C to 40°C, its temperature will increase. Consequently, the volume of the mercury will also increase due to thermal expansion, as most liquids expand when heated. However, the mass of the mercury will remain constant throughout this heating process.
Oil expand or contract when heated?
Oil does expand when heated and contracts when cooled.
Does matter expand or contract when it is heated?
Expand
What makes mercury in a thermometer go up and down?
Change in temperature is what cause the Mercury to expand up (hotter) or shrink down (colder).
What is the word equation for heated mercury?
The word equation for heated mercury is "mercury reacts with oxygen to form mercury oxide."
What happens to matter when heated?
When matter is heated it will expand
What expands when its heated?
Most substances expand when heated.
Do all objects expand when heated?
No, not all objects expand when heated. Most objects do expand when heated, but there are exceptions such as water between 0°C and 4°C, which contracts when heated. The expansion or contraction of an object when heated depends on its material properties.
Does matter expand or contract when it's heated?
Expand
Would wood expand when it is heated?
Wood would expand about 0.3 millimeters if heated to 100 degrees
