The energy comes from the gas which is usually a hydrocarbon fuel. The fuel produces heat energy when it burns with oxygen in the air.
The burning process releases chemical potential energy in the carbon. Carbon dioxide is produced and the carbon-oxygen chemical bonds in the carbon dioxide release heat when they are formed.
Most of the carbon in the gas was originally taken from carbon dioxide in the atmosphere by the action of plants. With the Sun's heat the plants separated out the carbon and oxygen, which resulted in stored energy, and that is the energy that runs the gas stove.
A gas stove uses natural gas or propane.
Chemical because a gas stove is using propane

A stove top gives off energy through the conduction of heat.
The heat energy from the stove, which in turn comes from the burning of the chemical energy in the gas that is burning, or from the electrical energy, depending on the type of stove.
Chemical Energy
The kettle uses heat energy. Depending on your type of stove, that heat will usually come from chemical energy (in a gas stove), or electrical energy (in an electrical stove).
chemical energy to heat energy
chemical
Potential, or stored energy (gas, electricity, wood) into kinetic energy, energy of movement (heat, light, increased temperature).
The Gas Stove uses a spark to start a flame, and that's what cooks the food.
None, Electrical energy is used to produce microwaves in a microwave oven.
