Equal in volume? The heavier on would be the denser one.
Equal in mass? They would weigh the same.
All solid can be liquified if the temperature is high enough.
it will condense and turn into liquids and if that cools too much it will turn to solid
When a liquid looses enough energy (heat), it turns into a solid.
Solids turn into liquids at their melting point.
Many liquids freeze (turn solid).Some liquids have great changes in their viscosity as they cool, some do not.Liquid Helium is an exception, there is no solid phase of Helium at standard pressure.
All liquids can get 'frozen', it just means they turn into a solid state. This point is called the melting point. this refers equally to point where solids turn liquid and liquids turn solid. However, because you do not specify what type of oil (you could be talking about gasoline/petrol, or talking about oils in food, palm oil) i cannot tell you at what point it would freeze.
Liquids all have their particles slightly apart, meaning they can flow but are still fixed together and cannot move too freely. When they turn into a solid it is called freezing, and when they turn into a gas it is called evaporating. The only liquids at standard temperature and pressure are mercury and bromine.
Some gasses turn into liquids when compressed (propane, butane), some turn into liquids when chilled to very cold temperatures (oxygen, nitrogen).
Different liquids have different freezing points. For water its 0 degrees celcius but other liquids will have different freezing points because of the element that make it up and the size of its molocules. ;)
Almost all solids will turn into liquid at some temperature.This process is called melting and the temperature at which the solid melts is its melting point.

A material in solid phase changes to its liquid phase by absorbing energy. The intermolecular(inter-particular) bonds are broken as the temperature increases until enough bonds are broken that the rigid shape of the solid can no longer be maintained.*The energy required to turn a solid into a liquid, of the same temperature, is called the latent heat of fusion.
