It is a liquid because at room temperature the molecular structure of the substance wants to expand. When the substance expands it goes from being a solid to a liquid. This expansion takes place when the room is at the commonly know "room temperature"
Octane is a liquid at room temperature (it's one of the main ingredients of petrol/gasoline). If you mean what will it mix with, the answer is any other hydrocarbon liquid such as hexane or heptane or nonane.
Oils that are normally liquid at room temperature are turned into room temperature solids through hydrogenation. Hydrogen gas is bubbled through vegetable oil in the presence of a catalyst, forcing additional hydrogen bonds onto the hydrocarbon.
A hydrocarbon only has carbons and hydrogens, all single bonded. The way it is packed makes it hard to stay together at room temperature, so it is a liquid. However, lower temperatures should make it easier for molecules to stay together as it decreases its kinetic energy.
Yes. If you are talking about the thing in thermometers, yes, they are liquid.(metal- liquid) Mercury is one of the few metals that is a liquid at room temperature. Other metals, as you know, are solid at room temperature.
Mercury is the only metal that is liquid at room temperature. Mercury (Mg) with atomic number 80. It is the only metal that is liquid at room temperature. Another element that is liquid is bromine but it is a non-metal.
