Because the gas inside expands with the heat
When a balloon is heated, the air molecules inside the balloon gain kinetic energy and move faster, causing them to spread out and take up more space. This increase in volume leads to the balloon expanding.
For a balloon that is sealed and not full the volume of air inside the balloon will increase as it is heated. This is not however how hot air balloons work. A hot air balloon is essentially a fixed volume when it is inflated. If the air inside the balloon is heated the air inside becomes less dense so some of the air exits the balloon via the mouth of the balloon. As the air inside the balloon cools it becomes more dense so some air is ingested via the mouth of the balloon to keep it full. With each heating and cooling cycle, the pressure inside the balloon remains constant, the volume of the balloon remains constant but there is this movement of air out of and back into the balloon. P=VT Poop
If the air inside a balloon is heated, the volume will increase because the molecules move faster and spread out, causing the air to expand. Conversely, if the air inside a balloon is cooled, the volume will decrease as the molecules slow down and come closer together.
If a balloon is heated, the temperature inside the balloon increases, causing the air molecules to move faster and collide more frequently with the walls of the balloon. This increase in collisions leads to an increase in pressure inside the balloon, assuming the volume remains constant according to the ideal gas law (P1/T1 = P2/T2).
Charles' Law states that as temperature of a gas increases, its volume also increases if pressure remains constant. When a balloon is heated, the air inside it warms up and expands, causing the volume of the gas to increase. This increase in volume causes the balloon to rise because it becomes less dense than the surrounding air.
The kinetic energy of the particles inside the balloon increase. This then expands the volume of the balloon.

The increase in volume of a material when heated is called thermal expansion.
When a balloon is placed in hot water, the air particles inside the balloon gain energy and move more rapidly, causing them to exert more pressure on the walls of the balloon. This increase in pressure leads to the balloon expanding in size as it tries to accommodate the higher pressure from the heated air molecules.

The volume will increase in proportion to the increase in absolute temperature.
When a balloon is heated and its volume doubles, the density of the air inside the balloon decreases. This change in density causes the balloon to rise since it becomes less dense than the surrounding air. The balloon will continue to rise until the internal air reaches equilibrium with the external air.
