Why do many utensils have wooden handles?
Handles of cooking utensils are made of wood because wood is insulator of heat and so does not get heated while cooking. If they will be made of iron then it will get heated and we will not be able to hold them. Cooking pots are thus provided with wooden or plastic handles because they are bad conductors of heat. This prevents the heat from the pan to transfer to our hand. Thus, we can hold the utensils comfortably by our hands.

Class 3 EVS Chapter 10 Extra Important Question Answers
What is steaming? Give few examples of food made by steaming
Steaming is a moist-heat method of cooking that works by boiling water which vaporizes into steam; it is the steam that carries heat to the food and cooks it. Steaming is a method of cooking using steam. This is often done with a food steamer, a kitchen appliance made specifically to cook food with steam, but food can also be steamed in a wok. Steaming is considered a healthy cooking technique that can be used for many kinds of foods. Few examples of food items which are steamed are- idli, momos, dhokla etc.
Name the different forms of fuels used for cooking.
The different fuels used for cooking are wood, charcoal, cow-dung cake, kerosene, biogas, LPG, etc. Among all these, biogas and LPG are least polluting. Liquid fuels include kerosene, methanol, ethanol and plant oil, whilst renewable gaseous fuels consist of wood gas and biogas. The fossil gaseous fuels are comprised of petroleum gas (LPG) and natural gas.
How does the fuel used in our homes affect the environment?
When we burn oil, coal, and gas, we don’t just meet our energy needs but we pollute the environment and increase the rate of global warming crisis as well. Fossil fuels produce large quantities of carbon dioxide when they are burned. Carbon emissions trap heat in the atmosphere and lead to climate change.
Which cooking fuel is most environment-friendly and why?
For the cooking purpose, natural gas, methane, and LPG are used as they are environment-friendly and do not cause pollution. Out of the fuels, Natural gas is very efficient. Gas burns cleanly with no soot or ash, and therefore produces lower emissions. It is considered the most environmentally friendly fossil fuel.
How does cooking food in a pressure cooker save time and fuel?
Cooking food in a pressure cooker saves time and fuel as under pressure, the heat builds faster and maintains temperature better, so cooking time is reduced. The increased pressure inside the cooker increases the boiling point of water above 100°C so more cooking is done before the water actually starts to boil. So ultimately food is cooked faster. When you cook with a pressure cooker you can save as much as 2/3rds of your energy use. The extra temperature makes the food cook faster. No extra fuel is consumed during this shorter time frame and food gets cooked faster at reduced cost.
What is kneading?
Kneading dough is as simple process which involves pushing the dough away from you with the heel of your palm, folding it over itself with your fingers, and pulling it back. This repeated push-pull cross-knits the protein strands, developing a strong gluten net.
