At what temperature are Celsius and Fahrenheit equal?
Celsius a Fahrenheit are equal at -40 degree. 0°C means the same temperature as 32°F. From this to get the same temperature you have to add 1 to Celsius and 1.8 to Fahrenheit.

A National Geographic study says, that a molecule used by the heart  is the most likely culprit. It sends a message to the spinal cord, making us feel itchy. This study also suggests, that we may in the future be able to block this molecule from signaling the spinal cord,  potentially helping people with cronic itching.

You can desalinate seawater. There are multiple methods of doing so, such as reverse osmosis, distillation and vacuum freezing. currently there are more than 7500 desalination plants around the world, 60% of which are in the Middle East.

A sunstroke/heatstroke is a spectrum of disorders which are due to environmental heat exposure. This is a potentially life threatening condition. The problem starts when the body's inner temperature rises above 40 C. Some symptoms of a sunstroke are: headaches, nausea, vomiting, extreme thirst, disorientation, feeling confused, losing consciousness and of course feeling extremely hot.

Dinos died 65 million years ago, but we still don't know it for sure what caused this. The only thing we know that at this time a huge meteorite hit the earth (somewhere at todays Mexico). Another theory is about lots of volcano eruptions threw 700 000 years around at todays India. There is a third theory: there was a slow climate change happening, that deprived the animals of their food sources. The most likely to happen was maybe all the three of these. Lynn

Sweating plays an important health role, because it helps to cool our body down. There are two types of sweat glands: eccrine and apocrine. Eccrine glands activate as our body tempreture rises. Apocrine glands are also triggered by our body tempreture rising, but are also triggered by stress, anxiety or certain hormones.

Popcorn is a special kind of corn. Of all the types of corn, popcorn is the only variety that pops.

Inside each kernel of popcorn is a tiny droplet of water surrounded by a hard shell called a hull. As the popcorn is heated, the water turns into steam, which builds pressure inside the kernel. When the hull can no longer contain the pressure — POP!

For first of all, it's in your genes. So basically if someone in your family has freckles, you've got a very big chance to also have. Freckles are also caused because of the melanin (pigment protein) in your body. This melanin shows up when UV hits your skin.

This is because salt lowers the melting point of water. Adding 10% salt to ice would change its melting point to - 6°C. This is because the salt dissolves into the water in the ice.

Yes, they can, though it's more like dozing.
It does not affect their flight, because they literally keep one of their eyes open in order not to crash into each other. Occasionally, the birds enter into REM sleep. The only difference is that for birds, it only lasts for seconds, so only their heads dip a little.

Cats purr for two main reasons. They mainly do it to express contentment, happiness and pleasure. But they also purr when they're in pain or are injured, one example is when giving birth. So it's suggested, that purring is a kind of self-repair/ natural healing mechanism, which helps them rest and repair.

Lobsters are cooked alive because of things called "vibrio bacteria". These things live on the decaying body of lobsters and cause severe food poisoning. We boil lobsters alive since there is no effective way to get rid of these bacteria after they've settled. As for lobsters feeling pain, we actually do not know for sure yet.

The air is composed mostly of nitrogen (78%) and  oxygen (21%).
Nitrogen is a type of gas which is a non-toxic gas, though in an enclosed place it can replace oxygen, making the usually non-harming gas actually suffocating.
Oxygen is a type of gas which is useful in many ways. It's often used in medicines, but it's playing a big part in ensuring that everything stays alive.
