General cultural and scientific information
The Pacific Ocean covers one third of the Earth. About 90% of the world's population lives in the Northern Hemisphere, and about 70% of the world's population lives in Europe and Asia. The highest temperature recorded on Earth is 56.72 ° C in California's Death Valley in the United States, and the lowest temperature on Earth is -94.7 ° C in eastern Antarctica. China is the world's largest rice producer, producing 33.9% of the world's rice supply, and Thailand is the second largest rice producer and exporter in the world. [2] Lake Victoria is the largest lake in Africa, located in the east. Africa is on the border of Uganda, Kenya and Tanzania, the second largest freshwater lake in the
world, after Lake Superior in North America. [2]
Indonesia has the largest Muslim population in the world, with Muslims accounting for about 87% of Indonesia's population. Accordingly, Indonesia has about 188 million Muslims. [2] General chemical information The following points illustrate some general chemical information:
[3] Oxygen is colorless, but it is blue in liquid and solid states. A pure element can take many forms; for example, diamonds and graphite are forms of pure carbon. The only metals that are not silver in color are gold and copper. The water level falls rather than overflows, when you put a handful of salt in a glass full of water. Unlike many materials, water expands when it freezes. The ice cube occupies 9% more volume than the water used to form it. Helium balloons float in the air because helium is lighter than air. Mars is red because its surface
contains too much iron oxide or rust. A person is thirsty when he loses about 1% of the water in the body. Bromine and mercury are the only elements present in liquid form at room temperature, and a large mass of gallium can be dissolved by hand-held heat. Some general c
ultural information The following points illustrate some general cultural information: [4] A hippopotamus does not have a stomach in its body. Often small. The heart of King Richard the Lionheart is now in the form of a pile of ash; his heart was removed and kept, after his death in 1199 AD
Prosoopagnosia is a mental disorder that affects people and makes facial recognition difficult. Camels can store 113 liters of water in just 13 minutes. This water is stored in the bloodstream rather than in its fatty hump, which is the source of nutrition when food is scarce. Gravity on the moon is one sixth of the Earth's gravity.For example, when a person weighs 68 kilograms on Earth, it weighs only 11 kilograms on the moon. This is because the moon's gravity is much lower than Earth's gravity, because Only one percent of the Earth's mass, and if man were to stand on the surface of Jupiter, his weight would be twice that of Earth. The adult human skeleton consists of 206 bones; the smallest is the passenger bone, one of the three deep bones in the middle ear. The femur is the longest and strongest bone in the body. Bones together.
