It's not so much whether they are primary or secondary; the waves that can't travel through liquids, or gases for that matter, are transverse waves.
The velocity of sound in vacuum is 0 m/s because sound requires a medium, such as air or water, to travel through. In the absence of a medium, sound waves cannot propagate and therefore, there is no velocity of sound in vacuum.
Sound travels a little slower through gases compared to liquids and solids. This is because the particles in gases are farther apart, leading to a slower transmission of sound waves.
Yes, conduction can occur in liquids and gases, although it is less efficient compared to solids. In liquids and gases, conduction is primarily due to the transfer of heat by the collision of molecules. Materials like metals are better conductors than liquids and gases because their molecules are more closely packed.
A medium can exist in three states of matter: solid, liquid, and gas. Solids have a fixed shape and volume, liquids have a fixed volume but take the shape of their container, and gases have neither a fixed shape nor volume.
A glass trough is a long, shallow container made of glass usually used for holding liquids or small items for observation or experimentation. It is commonly used in laboratory settings for activities like titrations, chemical reactions, or cultivating plants.
Egypt.
yes
A perfect vacuum
No, because there is no substance to propagate.
This is because the Outer Core is liquid, and we know from experiments that S-waves cannot travel through liquids. If they could pass through the outer core, they could pass through the Inner, but they are absorbed by the first barrier, at the Gutenberg Discontinuity.

we just travel through dimension,s like any normal human would.
He had to do some navigation to travel trough the sea.
