Xrefer Brainteaser: Hot and Cold

Disappointed that House is not on tonight - Mum scrolled through her backlog of newsfeeds and found a recent brainteaser...

Cricket identified snow from the "dictionary definition: "Precipitation in the form of aggregations of ice crystals falling to the ground in soft white flakes, or lying on the ground as a soft white mass"."

Cricket identified correctly that direct sunlight causes sunburn from UV (ultraviolet) rays.

For measuring temperatures, Cricket guessed first at "Fahrenheit", but immediately agreed with Mum's suggestion of " Celsius" as the word officially replaced "centigrade" in 1948.

We learned that Frostbite is what made the explorer Sir Ranulph Fiennes abandon his solo trek to the North Pole in 2000.

Cricket was correct this time that Fahrenheit is the name for the scale of temperatures in which 212 degrees represents the boiling point of water.

Fish & Cricket both immediately declared Antarctica to be the coldest continent on Earth.

Cricket correctly remembered (he thinks from M*A*S*H) that "Pyrexia" is another word for Fever.

Mum couldn't call to mind the phrase absolute zero to describe the point at which it would be impossible to get any colder (minus 273.15 degrees C)?

Mum guessed correctly that in 1626, the famous person who died of a cold contracted when stuffing a fowl with snow as an experiment in refrigeration was Francis Bacon not Christopher Marlowe or William Shakespeare?
