Australia’s southern states are scorching in extreme heat that could break temperature records in Victoria and South Australia on Tuesday.
At Ouyen and Mildura in north-west Victoria, temperatures of 49C were forecast for Tuesday afternoon. If reached, they would break the state’s all-time temperature record of 48.8C, set in Hopetoun on Black Saturday in 2009. By 1pm, temperatures of 46.2C in Ouyen and 44.8C in Mildura had been recorded.

In Adelaide, the mercury hit 40C before 9.30am on Tuesday, after overnight lows of 35C, BoM observations showed.
Extreme heat is the most common cause of weather-related hospitalisations in Australia, and kills more people than all other natural hazards combined. What does exposure to extreme heat – such as a temperature of 49C – do to the body?
Boiling water is full of pockets of steam that may be higher than 100C, and will have cold spots too. It’s really not very easy at all to get any quantity of water to 100C stably and consistently throughout. Not easy enough to be a foundational reference, with the tools of a century or two ago. Boiling is also sensitive to altitude and pressure changes, and may be shifted slightly based on the mineral content of the water. It is in fact not dead simple.
No it won’t, who told you that? That’s not how thermodynamics works
Yes it will. Who told you it won’t? This is how thermodynamics works.
The second law?
Please explain how there can be a cold zone in boiling water, I’m dying to learn.
You think every molecule in a pot of boiling water is at exactly the same temperature? Of course there are variations throughout. You don’t need to invoke the fundamental laws of the universe to figure that out.
