Which of the four glasses of water evaporates the fastest?

It depends on the surface area of ​​four glasses of water.

The factors that affect the evaporation of liquid should be considered from three aspects: temperature, surface area and air flow. The larger the surface area, the faster it evaporates. The higher the temperature, the faster. it evaporates. The faster the air flow, the faster it evaporates. Faster, you need to judge which cup of water evaporates faster based on these three points.

Regardless of the type of liquid, it can evaporate at normal temperatures, but the speed of evaporation is very different.

Remember! Drink four glasses of water a day! Pay attention to the quantity, duration and temperature!

Scientifically speaking, mixing four cups of water at 25 degrees won't make 100 degrees. Why ?

Things in nature are objective and will not change due to human subjectivityand artificial regulations. The Celsius temperature scale states that under standard atmospheric pressure (about 101 kilopascals), the temperature of the ice-water mixture is 0 degrees and the boiling point of water is 100 degrees. This provision is purely for human convenience and is a subjective provision. Therefore, nature “does not understand” degrees Celsius and does not act accordingly.

In fact, to calculate how many degrees of water will reach 100 degrees when four cups of water are mixed, it must be calculated according to the Kelvin temperature scale. The target temperature of each cup of water is about 373 K, so the temperature of each cup of water should be about 93 K, which means it's actually four cups of ice at -180°C which will turn into water at 100°C when mixed.

You may want to ask: When used to express changes in temperature, 1K and 1℃ are equal. Why is the Kelvin temperature scale not subjective to humans? The reason is very simple. First of all, the concept of absolute zero is objective and not subjectively defined by humans, as long as the Kelvin temperature scale of absolute zero is specified as 0K, regardless of the magnitude of the temperature change. , it will not affect the actual calculation. This is why the ideal gas equation is based on the Kelvin temperature scale.

Have you followed the right detoxification program for the human body?

It is said that Drinking water is the best food for the body.

As for the elderly

Are there any special requirements regarding drinking water?

Let me tell you

You need to drink four glasses of water every day

I first took out the first glass of water

p>

The quantity is relatively small

Cth first glass of water

When should I drink it?

The first glass of water

Drink before going to bed

Some people ask

Can I still sleep afterwards having drunk this glass of water

I will definitely be up all night

But do you see how much water is in this glass?

About 50-100 ml

< p> This glass of water is You should drink it before going to bed

After drinking it, it has a very good protective effect and regulator on gastrointestinal blood vessels and nerves

> Can help sleep

What you need to pay attention to is the quantity and temperature

Physics question: Four identical glasses are filled with water, and the height of the water surface is different. What is the tone?

The right detoxification program for the human body, are you doing it correctly?

Human health program:

Slimming time: different moments with different sports sciences Effective and rapid weight loss.

Time to drink water: Drink 8 glasses of water every day. We will explain in detail when you should drink water.

Memory Time: Teaches you how to use memory time effectively to improve learning efficiency and achieve twice the result with half the effort.

Teaching time: Teach yourself to use your time efficiently and spend as little time as possible to become a bad student and counterattack the best student.

Detox time: Do the right things at the right time to teach yourself scientific health care and stay healthy.

Time of skin care: Scientific skin care at different times and using different methods to develop milky skin.

The correct water consumption schedule for the day:

First glass of water - 6:30 a.m. - nclean the stomach.

Second glass of water - 8:30 a.m. - Increases energy.

The third glass of water - 11:00 a.m. - increases satiety.

The fourth glass of water - 1:00 p.m. - promotes digestion.

The fifth glass of water-3:00 p.m.-refreshing.

The fifth glass of water - 5:30 p.m. - reduces fatigue.

The sixth glass of water-7:00 p.m.-detoxification and excretion.

The eighth glass of water - 9:00 p.m. - Prevent blood thickening.

The best time for golden memory:

6:00-8:00:

The most suitable time for memorization, it is recommended to read and memorize words early.

8:00-11:00 a.m.:

Short-term memory is better and you can review items that will be tested soon.

11:00-12:00:

The brain and body are tired, so it is recommended to listen to music to relax.

The skin care program adapted to the human body:

6:00 a.m.-8:00 a.m.:

The skin is prone to edema. The oil secretion has overflowed from the skin and forms an oily film on the surface of the skin, which needs to be cleaned in time.

8:00 a.m.-12:00 p.m.:

This is the time when the skin's resistance is strongest, so it is recommended to carry out hydration and whitening work.

12:00-15:00:

The body feels tired and the absorption capacity of the skin weakens. At that time, the peau can be relaxed and it is recommended to use moisturizer. mask appropriately.

3:00 p.m.-8:00 p.m.:

This is a good time for the skin to fully absorb nutrients. At that time, applying a facial mask or moisturizing will have a significant effect.

8:00 p.m.-11:00 p.m.:

The skin's resistance is weakened. It can cleanse the skin but is not suitable for deep nourishing or intensive care and has little effect.

11:00 p.m.-5:00 p.m. the next day:

The growth and repair functions of skin cells are at their peak, so rest is recommended.

The two situations are different. When you tap a glass, the cup with a higher water surface area will have a higher pitch, and the opposite will be true for the cup with a lower water surface area. Because water vibrates to produce sound, this is related to the height of the water. If you blow with your mouth, the sound will be plower if the water surface is higher, and vice versa. Because air vibrates to produce sound, this is related to the amount of air in the bottle.

The above is a theoretical conclusion. But if you actually experiment, sometimes the results will be different. This is what our physics teacher says, so this kind of question is usually not tested in the exam.
