For a reaction with a positive enthalpy change (ΔH > 0) and a positive entropy change (ΔS > 0), the spontaneity is influenced by temperature through the Gibbs free energy equation: ΔG = ΔH - TΔS. As temperature increases, the TΔS term becomes larger, which can make ΔG more negative, thereby favoring spontaneity. Therefore, at higher temperatures, the reaction is more likely to be spontaneous, while at lower temperatures, it may not be spontaneous.

it is never spontaneous
Yes, the sides are lengths and those are positive. Even a degenerate triangle which is 3 collinear points joined by line segments has positive sides. (it's angles add up to 180 and its area is zero, by the way but the usual triangle lies in a unique plane while the degenerate one does not)
length
Sure, that is exactly what the triangle inequality tells us!
The triangle symbol in a chemical reaction typically indicates heat being applied to the reaction. This signifies that the reaction is being carried out under specific temperature conditions, often to speed up the reaction or facilitate the desired chemical transformation.
A positive triangle symbol (Δ+) above a molecule indicates that the molecule is electrophilic, meaning it can accept electrons in a chemical reaction. This symbol is often used in organic chemistry to represent an electron-deficient species that can react with nucleophiles.
changed
the temperature has changed
It means that it's a triangle with a certain amount of temperature in degrees Fahrenheit. It could also mean that a certain triangle has a temperature inside it.
It means the temperature has changed.
reached the maximum level allowed.
The reaction increased in order
The change in Gibbs Free Energy (∆Gº) predicts if a reaction is spontaneous or not. The equation for this is ∆G = ∆H - T∆S where ∆H is the change in enthalpy, T is temperature in Kelvin, and ∆S in change in entropy.
A combustion reaction involves the three reactants from the fire triangle, heat, oxygen, and fuel.
