1. Hot water freezes faster than cold water?
This fact appears counterintuitive, however, it’s referred to as the Mpemba effect, after a Tanzanian student named Erasto Mpemba World Health Organization told his teacher than a hot mixture of ice cream froze quicker than a cold one. Scientists currently believe this is often because the velocities of water particles have a specific disposition whereas they’re hot that permits them to freeze more readily. If proved correct, this finding may even have implications in daily life, like cooling down electronic devices.
2. Stomach acid is strong enough to dissolve stainless steel?
Your stomach digests food thanks to extremely corrosive hydrochloric acid with a ph of two to three. This acid also attacks your stomach lining, that protects itself by secreting an alkali bicarbonate solution. the lining still has to get replaced continually, and it entirely renews itself each four days.
3. A flea can accelerate faster than the Space Shuttle?
A jumping flea reaches dizzying heights of concerning eight centimeters (three inches) in a millisecond. Acceleration is that the change in speed of an object over time, usually measured in ‘g’s, with one g equal to the acceleration caused by gravity on Earth (9.8 metres/32.2 feet per sq. second). Fleas experience one hundred g, whereas the space shuttle peaked at around five g. The flea’s secret could be a stretchable rubber-like protein that permits it to store and release energy like a spring.
4. Only one letter doesn’t appear in the periodic table?
It’s the letter J. go ahead and check.
5. In 2.3 billion years it will be too hot for life to exist on Earth?
Over the approaching hundreds of millions of years, the Sun can still get increasingly brighter and warmer. in only over two billion years, temperatures are going to be high enough to evaporate our oceans, creating life on Earth not possible. Our planet can become a massive desert almost like Mars these days. as it expands into a red giant star within the following few billion years, scientists predict that the Sun can finally engulf Earth altogether, spelling the definite finish for our planet.
