When a liquid is heated the part that is at the base heats up quickly and rise up due to it being less dense, this movement is called convection. The cold liquid is denser so it goes downwards. That why liquid is hot at the top.
Yes, it changes, because when orange juice becomes warm/hot, it becomes more of a base, and when it turns cold, it becomes more of an acidic liquid.
It becomes hot liquid.
Lava.
No, mercury does not become solid in hot temperature and liquid in coolest temperature. But mercury becomes gas or liquid in hot temperature and becomes solid in coolest temperature. Mercury becomes solid after freezing point of -38.72 degrees Celsius. Solid Mercury can become superconductor in reaching of its critical temperature 4.2 K. Mercury is liquid under the room temperature (25 degrees Celsius). Mercury becomes gas after boiling point of 357 degrees Celsius.
Depends. Water vapor for example is a gas. When water vapor condenses in the atmosphere, it comes back as precipitation (rain, liquid). When liquid becomes too hot, it evaporates into gas. When gas becomes too hat, it becomes plasma. When liquid becomes too cold, it becomes a solid.
Conduction.
The rock becomes too hot that it must turn into liquid form (lava). This would usually mean that the rock had to have come into contact with lava first.
Melting is when something becomes too hot and melts! LOL! Easy as that! It becomes a fluid and it becomes gross!
hot porridge is soluble as it it in the liquid form.
YES <><><><> FLOWING lava- still liquid- is VERY hot- over a thousand degrees. As lava cools, it thickens, and becomes hard (rock)
First the liquid gets hot, then it boils becoming a gas.
soup is the first course because the hot liquid mixed with herbs and spices wake up the tastebuds in your mouth which causes a more enjoyable partaking of the main course
