In heat, the atoms or molecules making up any substance (e.g. a rock) start to move faster, because they are gettting more energy from the heat. since they move faster, they are also able to vibrate (in the case of a solid) more, and so can get further away from the centre of the objext.
This causes the illusion of expansion, although the mass of the object remains the same.
Oil does expand when heated and contracts when cooled.
they expand
No, liquids do not always expand uniformly with temperature. Generally, liquids expand as they are heated, but the expansion may not be uniform due to factors such as the specific properties of the liquid and the conditions under which it is heated.
yes wires do because when the wires are heated the particles inside the wires change speed and move faster. this causes them to bump into one another and expand!
The rock melts, just like most other solids do when heated. Magma is to rock as water is to ice.
Oil does expand when heated and contracts when cooled.

When matter is heated it will expand
Most substances 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.
Wood would expand about 0.3 millimeters if heated to 100 degrees
They expand
Matter expands when it is heated.
No, gases expand more than solids when heated.
Heat: non-uniform thermal expansion. If you heat a rock in one area, thermal expansion causes the volume to expand locally. Since the adjacent rock is not heated, the expanding volume of rock has nowhere to go (no room to expand.) Pressure builds, and the rock eventually fractures
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.
