When writing the chemical equation, how do you know water is in the liquid state?

The problem states that this is a combustion reaction at 25°C. The two products that come from combustion are CO2(g) and H2O - the H2O is liquid water because the combustion happens at room temperature.

The reaction takes place at room temperature, and water at room temperature is liquid.

when its a combustion reaction, I generally assume the water is in a liquid state.
