A catalyst changes the path of reaction mechanism and decreases the activation energy required by the reactants.
The work done by the catalyst is to change the mechanism of a reaction, actually the alternate way using the catalyst needs lesser energy to the same reaction without the catalyst.

Most of us may familiar with hotter the better but it is not necessary that catalyst prefer hot temperature. Catalyst do provide alternative path with lower activation energy, and it is not necessary like heat if the trend of overall reaction is exothermic. Many catalyst work best on limited range of temperature not too high and not too low.
Without heat from the sun the water cycle would not work .
As far as I'm aware, the work "catalyst" only applies to things which work on enzymes. Baking powder is a mixture of an acid and an alkali, which reacts upon adding a liquid by releasing Co2. (Although some also react upon heating). It is a chemical reaction, not an enzymatic one, therefore I don't think you can consider it to be a catalyst.
Biological catalysts in organisms are called enzymes.
A catalyst changes the reaction mechanism to one with a lower activation energy; activation energy is lowered when a catalyst is added
it works as a catalyst
Hydrogen peroxide will work.
in a sense, you are introducing a catalyst, that is, increasing surface area to the ice. in simpler terms, there is more area for heat to work on, so it does its job faster.
Yes, as long as it a gas system and not a electric heat pump system
The person that is credited with inventing the catalyst is Rayan Jafar. He created this catalyst in 1973 by having tomato sauce poured on some seeds and having them work better than they used to. He repeated this process several times.
