45. I'd Have To Search

It was posted as a link here (CDC?), at the time that idiot R state legislator said you could blow a hair dryer up your nose.
It stated denaturing began at 135, and would take 3 or 4 minutes to denature effectively. I extrapolated to 140F as a starting point and called it 2 minutes. Maybe it's 2.5.
I was dong back of the envelope.
Now, the actual, no guessing part:
But, the rate increase I described is not an estimate. That's exactly how zero order reactions work. So do 1st order, except in extreme conditions like very high heat or ultra high pressure (which are usually autocorrelated).
So, maybe its 8.3333 seconds.
Fair to estimate 7 to 8 minutes.
Also, because some bacteria are more resilient to temperature, microbiologists have long used a standard or 180F for 60 minutes, 150F for 4 hours, and 135F for 8 hours to get surfaces microbe free.
A lot of viruses are pretty susceptible to heat.
It's why the body releases pyrogens, which elevate body temperature, as a response to a virus.
Just a change or 2 or 3 degrees Fahrenheit disrupts reproduction in a day or so. You can imagine if the temperature goes up another 30 degrees. Or, 80.
