What causes the force that pushes magma from the magma chamber through the pipe and vent of a volcano?

Under the Earth's crust the rocks are held in liquid form under high pressure and temperature. As the magma rises the dissolved gases in the magma expands and the magma forces out of the magma chamber through a pipe and out the vent of a volcano as lava.

i really hope this is right :/

The force of the reaction of gases and expanding gases inside the volcano pushes the magma from the magma chamber.

Inside the volcano and earth's crust, there are:

several gases
reactions carried out.

The reactions release heat energy. The byproducts formed gases exert force onto the magma of the vent or pipe.

As soon as the internal force of expanding gases overcomes the external atmospheric pressure, there is an eruption of the volcano releasing magma through the pipe or vent of the volcano.
