Yes, both the alkali metals and the alkaline earth metals with react with oxygen. The alkali metals will do so rapidly even at room temperature, cesium and rubidium self-ignite on contact to air.
Because they are highly reactive as they react with air, oxygen and moisture readily even at room temperature.
For oxygen to be a liqud it has to be extremly cold and to be a liquid it has to be even colder. Room temp is quite hot. If you want more information have a look at wikipedia.
Titanium wont mix with Oxygen at room temperature, but once heated to a high enough temperature, it will react with Oxygen to form Titanium Dioxide - a white powder which is often used in the food industry or in paint. Titanium cant be melted in air, it has to be melted in a vacuum, or in an Argon atmosphere, as Argon is inert and wont react with the metal. If heated in air to sufficient temperature, it will burn very brightly, reacting with the nitrogen and oxygen.
Yes, graphite reacts with oxygen but not at room temperature. The temperature has to be quite high ;)
Nothing, It will sink but it won't react with water at room temperature. You have to heat graphite to something like 800 degrees Celsius to react with water at that temperature it will react with steam to produce carbon monoxide and hydrogen gas.
Magnesuium burn in air at room temperature.
Graphite is carbon at any temperature.
No, they generally do, even at room temperature.
Graphite is a solid.
Energy! Methane is a stable molecule and oxygen is almost (pretty) stable. The there is sufficient energy, called activiation energy, then the two gases will react
Graphite does not sublime or melt under normal room temperature. However; it does sublime if the temperature reaches 3652-3697℃.

No. Oxygen is gaseous at room temperature.
