Electrostatics and everyday life

• When you take off a pullover over a nylon shirt there is a crackling sound.
• A pen rubbed with a piece of cloth will pick up small pieces of paper.
• A television screen collects dust easily.
• If you roll over in bed you can sometimes see small sparks between the sheets.

The examples of electric force are as mentioned below: The charge in a bulb. Electric circuits. Static friction between cloth when rubbed by a dryer.

Electric Force Examples coating of charged powder particles are attracted to an oppositely charged object. balloon against your hair will create enough static charge to make the balloon ‘stick’ to a wall.

What is the Importance of Magnets in Our Daily Life?

• Computers and Electronics: Most computers have magnets built into the interior.
• Electric Energy and Other Industries: Magnets are considered as one of the most important elements used in the industry sector.
• Health and Medicine: Magnets are also used in medicine.

Examples: A light bulb, the glowing coils on a toaster, the sun, and even headlights on cars. Electrical Energy – Energy produced by electrons moving through a substance is known as electrical energy. We mostly see electric energy in batteries and from the outlets in our homes.

Let’s have ten examples of Physics in everyday life:

• Alarm Clock. Physics gets involved in your daily life right after you wake up in the morning.
• Steam Iron.
• Walking.
• Ball Point Pen.
• Headphones/Earphones.
• Car Seat-Belts.
• Camera Lens.
• Cell Phones.

Physics extends well into your everyday life, describing the motion, forces and energy of ordinary experience. In actions such as walking, driving a car or using a phone, physics is at work. For everyday living, all the technologies you might take for granted exploit the rules of physics.

One can find chemistry in daily life in the foods we eat, the air we breathe, cleaning chemicals, our emotions and literally every object we can see or touch. Here’s a look at examples of everyday chemistry. Some common chemistry may be obvious, but others might surprise us.

Science is involved in cooking, eating, breathing, driving, playing, etc. The fabric we wear, the brush and paste we use, the shampoo, the talcum powder, the oil we apply, everything is the consequence of advancement of science. Life is unimaginable without all this, as it has become a necessity.

Through science and technology, it is easier for inhabitants to communicate with other people around the globe. It is also significant in the field of business because transactions and other events are done through the computer. Science and technology enables every people to live in an easy and modern way of life.

It contributes to ensuring a longer and healthier life, monitors our health, provides medicine to cure our diseases, alleviates aches and pains, helps us to provide water for our basic needs – including our food, provides energy and makes life more fun, including sports, music, entertainment and the latest …

The process of cooking, baking, and preparing food is essentially an applied science. Bread baking provides a great example of the importance of having a scientific understanding of cooking and baking. Large biological molecules such as proteins, carbohydrates, and fats comprise the basic building blocks of food.

Cooking is more of an art than an exact science, but as it happens for baking, being fairly exact is important. In a way, but not really.

Cooking is both an art and a science, we can better understand as a science, but there is no way to remove the creativity from it. The visual representation of cooking lends itself to art. The technical part of cooking is based on science (chemistry, mathematics and physics).

“Cooking is definitely an art form because there is a lot of subjectivity involved. Cooking does not just depend upon reading a recipe and following directions, a lot of other aspects – like oven temperatures, ingredient interpretation, and mixing techniques – all factor into the dish.

Culinary arts

All this makes cooking the most versatile art form and in a way, a spiritual activity. Unlike other artistic mediums, it has the capacity to engage all the senses. Chefs have long known that the presentation of a dish is as important as the taste, aroma and texture of what is served.

1 : the art or practice of cooking. 2 : an establishment for cooking.

Cooking is the process of producing safe and edible food by preparing and combining ingredients, and (in most cases) applying heat. Cooking is a means of processing food, without which many foods would be unfit for human consumption.

Cooking food properly helps to avoid food poisoning. Most raw foods feature food-borne pathogens such as viruses, bacteria, parasites and viruses that can seriously harm and kill a human being. Cooking ensures that all the micro-organisms are destroyed, which make food safe for human consumption.

It makes food more appetizing and palatable. It makes food easier to digest. It makes food safe to eat. Cooking destroys many harmful micro-organisms or germs in the food.

Reasons For Cooking Food

• To change or improve the taste of the food e.g flour being used to make cake.
• To change or enhance the appearance of the food e.g. using rice to make fried rice, preserving mango to make jam.
• To change the texture (the way something feels) of food e.g. using cornmeal to make pastelles.

The process of cooking food breaks down some of its fibers and plant cell walls, making it easier for the body to digest and absorb the nutrients ( 17 ). Cooking also generally improves the taste and aroma of food, which makes it much more enjoyable to eat.

Methods of Cooking

• #1 Baking. This involves applying a dry convection heat to your food in an enclosed environment.
• #2 Frying. This means cooking your food in fat – there are several variations of frying:
• #3 Roasting.
• #4 Grilling.
• #5 Steaming.
• #6 Poaching.
• #7 Simmering.
• #8 Broiling.

The 6 Quickest (and Healthiest) Cooking Methods

1. Grilling. It’s best to use this quick method of cooking only for tender cuts of meat and fish, and for shellfish.
2. Griddling.
3. Stir-frying.
4. En papillote.
5. Steaming.
6. Microwaving.

Healthy cooking methods include:

• Steam, bake, grill, braise, boil or microwave your foods.
• Modify or eliminate recipes that include butter or ask you to deep fry or sauté in animal fat.
• Avoid added oils and butter; use non-stick cookware instead.
• Don’t add salt to food as it is cooking.

The three types of cooking methods are dry heat cooking, moist heat cooking, and combination cooking. Each of these methods uses heat to affect foods in a different way. All cooking techniques, from grilling to steaming, can be grouped under one of these three methods.
