When magma is underground it is under enormous pressure, which causes the gasses to dissolve in the magma. As the magma rises pressure decreases and the gasses come out of solution. All gasses expand when decompressed.
When magma reaches the surface, the gases dissolved in the magma are released due to the decrease in pressure. This release of gases can lead to explosive volcanic eruptions as the gases expand rapidly and forcefully.
Highly viscous magma with high concentrations of dissolved gases, such as water vapor, carbon dioxide, and sulfur dioxide, can lead to explosive volcanic eruptions. The buildup of pressure from these gases within the magma chamber causes a violent release of ash, lava fragments, and gases during an eruption.
As magma rises, the gases contained within expand due to the decrease in pressure on them as they rise. This creates bubbles that float through the magma, Like the sudden decrease in pressure on the gas in a carbonated beverage when opening, it's container releases a mass of rising bubbles.
Some of the trapped gas in a magma will be water vapour, but at very high temperature. As the magma rises in the volcanic pipe, the pressure will lower, and the entrained vapour will expand rapidly = an explosion.
When magma with a large amount of dissolved gases reaches the Earth's surface, the gases expand rapidly, causing pressure to build up. This can lead to explosive volcanic eruptions as the built-up pressure is released violently, ejecting magma, gases, and volcanic ash into the air.

All gases can and will expand in the right conditions.

Highly viscous felsic magma causes the most violent volcanic eruptions.
Magma with low viscosity, such as basaltic magma, typically causes quiet eruptions. This type of magma flows easily and allows gases to escape, resulting in relatively gentle eruptions with less explosive activity.
The three main causes of volcanic eruptions are the accumulation of magma beneath the Earth's crust, the buildup of pressure within the magma chamber, and the release of gases trapped in the magma. These factors can lead to explosive eruptions that result in the expulsion of ash, lava, and volcanic gases.
