Because the density of each liquid is different, the weight of the same volume of liquid is different. Milliliter is the unit of volume, which is 1 l = 1000cm in unit of volume conversion? , 100ml=0. 1 l = 100cm? Is the density of water 1g/cm? So 100ml of water is 100 g,100g =110kg = 2, which is 0.2kg..

Proper drinking water can avoid gastrointestinal dysfunction. You can drink some water half an hour after a meal to strengthen your digestive function and maintain your health.

The misunderstanding of drinking more water:

1. Because there are too many acidic foods, the acidity in the body is much more than the alkalinity. Therefore, for health, only natural weakly alkaline water is more suitable for long-term drinking.

2. People don't drink water all night during sleep, but breathing, perspiration and urination are still going on. These physiological activities need to consume a lot of water, but drinking salt water will aggravate hypertonic dehydration and make people drier. Moreover, the blood viscosity of human body is the highest in the morning. Drinking salt water will raise blood pressure, especially for people with poor heart function and high blood pressure.
