Chemistry is a branch of physical science that studies the composition, structure, properties and change of matter.
Daily water consumption varies quite a bit. Season of the year, workload, reproductive status, diet, and climate factor into the volume of water needed by a particular horse on a specific day. As a starting point, the average horse drinks between 5 and 10 gallons (19 and 38 liters) of water each day. The horse may need slightly less if it is grazing lush pasture because fresh grass contains a high percentage of liquid.
The advice to drink at least two liters of water every day seems to be a piece of common knowledge that everyone knows, isn't backed up by studies, as far as I can tell. My own theory is that sailors discovered by trial and error that they needed a gallon of water daily to remain in good health.oodstuffs that have high moisture contents also contribute to our water supply. With our food we absorb about 1 litre of water a day. Our total required amount of water is 2,5 litres a day. If we drink enough water and eat enough water-containing food, this should not be a problem.
