Not in the slightest.
Yes, most volcanic gasses are toxic and not good for the health, because they do not aid respiration and could lead to suffocation and death of living organisms.
The gasses of Venus are primarily volcanic emissions.
Death, major injuries etc.
In its elemental form it condenses our of volcanic gasses escaping from fumaroles.
Emission of water vapor and other greenhouse gasses!
More than warm. Gasses coming out of a volcano are usually very hot.
HYDROGEN SULFIDE It is one of the world's most toxic gasses It happens from Volcanic Activity
Mass burning , poisoined by toxic gasses and destruction by lava , or laharr[ mudslides] .
The answer will depend on what characteristic of the gases you wish to measure: the composition, pressure, temperature, etc.
When a volcano erupts, it releases many gasses into the air, but most of it is water vapor. Other gasses include CO2 and hydrogen. Also an interesting side note, if you Google "volcanic lightning" you will see that the lightning produced by volcanoes is a different color than regular lightning. This is because lightning is produced within the different gasses (other than oxygen, which is blue lightning).
No. Dissolved gasses trapped under pressure provide the force.
When, for various reasons, rock from the mantle melts, it sometimes moves to the Earth's surface through weak spots in the crust, releasing heat, gasses, and rock--a volcanic eruption
