Yes.
Pretty much every material expands when it gets hotter. Steels expand moderately, around 10-15 parts per million per degree Celsius.
Steel expands when heated because the heat causes the atoms within the steel to vibrate more, increasing the spacing between them. This expansion can be measured in terms of thermal expansion coefficients.
Steel expands by approximately 0.0000065 per degree Fahrenheit, per inch per inch when heated. So for one foot of steel (12 inches), it would expand by about 0.093 inches when heated to 1000°F.
Yes , just the same as steel - otherwise the rebar would crack structures !
The bar will contract (get shorter) as it cools down, and expand (get longer) as it is heated up.
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
