Lava is a liquid that flows similarly (but considerably slower) than water and acid. If the player or any mob comes in contact with lava, they will quickly take damage and die. Lava can be easily collected with a bucket and used to smelt items. Items and blocks,(other than liquids), that fall into lava are incinerated on contact.
Mixing lava and water will create cobblestone. If the lava is a(the/one) source block(s) (the lava block where lava flows out of) then obsidian is created. This same concept can be done if it comes in contact with rain.
