Conservatiojn of Energy is the reason gases expand when heatd. Gas energy is PV= RT, when Temperature T increases then RdT = PdV + VdP if the pressure is constant the dP=0 then RdT= PdV meaning the gas expands.
No, gasses expand when heated and contract when cooled.
the kinetic energy of constant pressure causes the gasses to expand. when they are heated, the molocules get bigger causing the gas to expand. if it gets hot enough, it will explode.
Liquids, solids and gasses EXPAND when heated- the particles occupy more space.
Liquids and gasses tend to expand when heated, this lowers the density, thus warm "air" rises and cool air falls.
Oil does expand when heated and contracts when cooled.

because hot gasses expand
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.
When matter is heated it will expand
Most substances expand when heated.

Wood would expand about 0.3 millimeters if heated to 100 degrees
