Lesson Content

What is an Electric Cooker?

An electric cooker is a kitchen appliance that uses electricity to cook food. It has one or more heating elements that get hot when you turn it on.

What is a Gas Cooker?

A gas cooker is a kitchen appliance that uses gas to cook food. It has one or more gas burners that produce a flame when you turn them on.

Differences Between An Electric Cooker and A Gas Cooker:

Electric and gas cookers differ in their fuel source, temperature control, and heating time. These include:

1. Fuel Source: Electric cookers use electricity, while gas cookers use gas.
2. Temperature Control: Electric cookers have set temperatures; gas cookers have a range of flame sizes.
3. Heating Time: Gas cookers heat up faster than electric cookers.
4. Cost: Electric cookers may have lower upfront costs, while gas cookers might potentially be cheaper to operate due to lower gas prices.
5. Environmental Impact: Electric cookers may be more environmentally friendly if the electricity source is renewable, while gas cookers emit greenhouse gases.

Uses of Electric And Gas Cookers

Electric and gas cookers are versatile kitchen appliances used for various cooking tasks. They are:

1. Cooking Food: These cookers are used to cook various foods.
2. Boiling Water: They boil water for drinks and cooking.
3. Warming and Keeping Food Warm: They keep cooked food warm.
4. Melting Chocolate, Butter, or Heating Ingredients: They melt ingredients for baking or cooking.
5. Frying: They are used for frying foods like eggs,plantain,and chicken.
6. Baking: Some cookers come with ovens for baking cakes, bread, and pastries.
7. Grilling: Certain models have grilling functions for preparing grilled meats and vegetables.
