What type of energy is used to bake a cake?
Thermal energy because you are using heat. The thermal energy can be supplied by an external heat source or by electric it generating microwaves which excite the water molecules to produce heat.
What energy source causes evaporation?
heat energy
What is the relationship between heat added to a system and the internal energy and external work done by the system-?
When heat is added to or is absorbed by a system, its internal energy increases. The amount of external work a system can do essentially refers to the amount of energy it can transfer to something else. So when internal energy increases, so does the external work done by the system.
Source of energy heat and light?
Sun

What type of energy does a steam in power plant have?
There is actually several answers, depending on what you are looking for in your answer. Heat energy, the energy that is imparted to the steam from an external heat source. motive energy, the energy in the steam that moves it through the piping. internal energy, the energy that causes the steam to expand. external energy, the energy that the steam holds that can be used to heat or drive machinery. and entropy, the unuseable energy that is lost in any energy system, (loss to the universe).
