Such tubes may develop excessive gas content if underloaded for long periods of time.

Letter groups are used to indicate the residual gas content of the 120 minute tissue.

Most of the local obsidian is black with low gas content.

The gas content is also called the "air content".

A high level of compressibility is linked to a high gas content in the fluid.

They are initiated by magma with very high viscosity and gas content.

Max measured the gas content of the fissure.

Original gas content ranges from 40 to 100 standard cubic feet per ton.

If two magmas have identical viscosities, it's the one with the highest gas content that's erupted most violently.

If, on the other hand, the same granitic magma had a high gas content, the result would be spectacularly different.
