A kitchen gas stove is one example. A laboratory Bunsen burner is another example.
it is both physical and chemical change
Methane is the IUPAC name for the main constituent in natural gas (CH4). Methane stores energy in the C-H chemical bonds and this stored energy is readily released as heat through a chemical process known as combustion (burning) which is a largely exergonic reaction.
It is a chemical change. Natural gas (UK) is a mixture containing principally methane. CH4 + 2O2 -> CO2 + 2H2O
Burning a fuel is a chemical change. Two or more substances are combined and new substances are produced with different properties than the original substances. In other words the gas and oxygen in the air are combined to form carbon dioxide and smoke.
Burning is a chemical process !
A kitchen gas stove is one example. A laboratory Bunsen burner is another example.
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.

Burning the gas fuel heat is released.
Burning is an oxydation reaction.
Methane is the IUPAC name for the main constituent in natural gas (CH4). Methane stores energy in the C-H chemical bonds and this stored energy is readily released as heat through a chemical process known as combustion (burning) which is a largely exergonic reaction.
went from wood burning to gas and in most cases no longer primary heating for home
Because of the gas stove, cooking utensils evolved from wood to heavy cast iron and tin, to lightweight aluminum, tempered glass, and ceramic. By the 1920s gas ranges were made of white porcelain enamel

On an electric stove, the heat coil directly touches the pot, facilitating the conduction or direct heat transfer. On a gas stove, the burning fuel transfers heat to a pot by both radiation and convection.
