This explanation would require helium II to have an abnormally low viscosity ... was devised. The viscosity was measured by the pressure drop when the liquid flows through the gap between the ...

At Ol Doinyo Lengai in northern Tanzania for instance, the lava flows at temperatures so low it is possible (though ... Lava with less silica in it has lower viscosity, meaning it is less thick ...

A lava tube may also form, beneath the surface of the ground, when low viscosity lava develops a hard crust through which lava flows.

Lava flows are masses of magma that pour onto ... called alkaline lava, has an extremely low viscosity, making it almost as fluid as water. Alkaline lava has a melting temperature in excess ...

It is formed by the eruption of highly fluid (low viscosity) lava, which travels farther and forms thinner flows than the more viscous lava erupted from a stratovolcano. Repeated eruptions result in ...

Based on your data, how does the viscosity of the liquid influence the rate at which the liquid flows? Nyiragongo is said to have lava that flows "like water." Based on your investigation ...
