When you heat a material, you cause the molecules to vibrate with more kinetic energy. So think of the Mercury as a group of people standing as close to each other as possible. If you add heat to this group (which can be represented by the people starting to wiggle their bodies and flail their arms) the group will start to take up more and more space depending on how much extra wiggling they do. This is a good comparison to the molecules of mercury. As they are heated, they vibrate with larger oscillations. This will mean they need more room to "wiggle", hence the mercury will 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).
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.
What expands when it is heated?
When heated, most substances expand due to the increase in kinetic energy of their atoms or molecules. This leads to an increase in the average distance between the particles, causing the substance to expand.
Which liquid expand on heating?
All liquids expand on heating (apart from water between 0oC to 4oC)
What is the correct capitalization and punctuated for the following sentence as particles become heated they expand and grow larger?
As particles become heated, they expand and grow larger.

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.
Oil expand or contract when heated?
Oil does expand when heated and contracts when cooled.
