Yes. More gas trapped in magma leads to a more explosive eruption. Water vapor is the most abundant gas in magma.

What are the two factors the control whether a volcano eruption will be explosive or quiet?
water vapor and high in silica
What type of material do explosive volcanoes produce?
An explosive eruption is caused by magma with a high content of water and silica. Non-explosive eruptions are caused by either lava because it is a thicker consistency, or magma with a low content of water and silica.
What happens if there is a lot of water present in the magma of a volcano?
The large amount of water would first increase the amount of magma, as it make it easier to melt rocks. Then the water vapor would help cause explosive eruptions.
Does water come out of a volcano?
Yes, as water vapor (steam).
How could water help a volcano?
It is unclear what it means to "help" a volcano, but water does tend to make eruptions more explosive.
Is a shield volcano nonexplosive or explosive?
shield volcanoes are only explosive if water somehow gets into the vent
What kind of vapor is in a volcano?
Often there is water vapor if it's a dormant volcano, and/or sulphurous fumes and hot gasses.. plus toxic farts...
Why do you think water vapor erupt from a volcano instead of liquid water?
A volcano vents water vapor instead of liquid water because that water has been in contact with very hot rocks, well above the boiling point of water. Some of the water vapor comes from the molten magma itself.
What is trapped in magma that can cause explosive eruptions?
Gas, primarily water vapor.
Why is Kilauea volcano non explosive?
Kilauea is a shield volcano fed by gas-poor basaltic magma. It is the gas in the magma that makes eruptions explosive. Kilauea has occasionally produced explosive eruptions when magma cam in contact with water.
Two factors control whether an eruption will be explosive or quiet?
