Verkhoyansk, a Siberian town in Sakha Republic, Russia, is one of the coldest inhabited places on earth. This town holds the Guinness World Record of having the highest temperature range in the world. Temperatures in peak winter season are as low as –45 degrees Celsius. In summers, the average temperature is around 16 degrees Celsius….
Butterflies are delicate creatures and they are affected by climate change. A large population of butterflies indicates a healthy ecosystem and a dearth of butterflies indicates that the ecosystem is under stress. Butterflies are unable to fly if their body temperatures drop below 30 degrees Celcius.
In about 1607, Galileo invented an instrument that could measure the rise of water in a glass tube with the rise in temperature. This instrument is called a thermoscope. Later, scientists modified it to add a scale to mark the rise of water. Subsequently, water was replaced with alcohol and mercury.
The boiling point of water decreases with the reduction of atmospheric pressure. Since the pressure at an altitude of 8,848 m gets highly reduced, the boiling point of water also gets drastically reduced. With every 285 m of elevation, the boiling point decreases by 1 °C. The boiling point of water on Mount Everest (8,848…
