Dry heat requires chemicals for sterilization instead of heat. It takes about 6 seconds and the temperature increases only a few degrees. All bacteria, viruses and endospores are killed immediately.

Does cold water have more germs than hot?
It doesn't matter which temperature it is because germs only start dying when it reaches boiling point which is burning and some sinks don't go up to that temperature so that's why people use soap/antibacterial wash.
Is it better to wash your hands in warm or cold water?
Although the FDA mandates warm water for those in food service, the CDC says any temperature is fine, so it's a bit of a contested subject.Heat is known to kill bacteria, but the temperature and duration of exposure required would seriously damage human skin, so that argument for warm water is a bust. Additionally, some advocate for washing in cool water because it uses less energy and is therefore more environmentally friendly.Anyway, no matter the temperature, washing your hands thoroughly with soap for 20 seconds is good practice.
What does sanitizer do?
Sanitation minimized the risks of diseases, illnesses and even death.A bit more:Sanitation destroys germs that cause disease and illnesses. This can be done by using extreme heat or certain chemicals, such as bleach.
Infer if a substance can contain thermal energy can a substance also contain heat?
Thermal energy and heat are the same thing to a scientist, maybe not to the man in the street. All substances on earth contain thermal energy (or heat energy). It comes from the vibrations of the atoms and molecules. Scientists have worked out that to stop the vibrations we'd have to cool things down to about -273oC. And we haven't quite got that cold yet. So, while a writer might say something like, "All the heat had left my toes and I was freezing cold." a scientist would say, "I'd lost some heat energy from my toes to the environment as the heat energy tried to reach equilibrium. I felt cold because my toes were radiating heat faster than I could generate it and the heat energy left in them was not enough to keep me comfortable." Which possibly explains why scientists don't write the best fiction!
Why is James Prescott Joule named after a unit of measurement?
he was the one who discovered that Mechanical Energy(ME) and heat were proportional
Do dishwashers really work killing germs?
Yes, the heat definitely kills germs.
What have scientist already discovered about heat and evaporation?
that the more heat u have the quicker the evaporation
Which scientist discovered heat resistant bacterial spores?
Ferdinand cohn
How hot do the farmers heat the milk when getting the germs out of it?
175 kills all bugs. Most go to 190 f
What scientist discovered sound energy heat energy or light energy?
katey uranous hilip
What happens if a fly is cooked in food?
Probably nothing will happen. Any germs the fly had most likely were cooked away. Heat kills pathogenic bacteria.
What was the importance of Louis Pasteur's research into germ theory?
he discovered a process called pasteurization.It showed that heat can kill germs.If we heat milk for half an hour at a certain temperature and then cool it ,the germs in it are killed.It was an important invention.It is safe to drink pasteurized milk as it is free from germs,so it cannot cause any disease.
Do employers have to heat restrooms?
kill bacteria and germs i the air
What is heat sanitizing?
using the heat from an open flame source on the surface of an object to kill the germs and bacteria with intense heat.
How do you get sheets really clean if they have a pattern and can't be bleached?
Machine wash sheets on warm or cold. Then machine dry them with heat. The hot drying process usually kills any germs that may have survived machine washing. anonymous@oola.com
How do they clean cow milk?
First you keep the cows and all milking equipment clean.After milking the collected milk should be pasteurized, which uses high temperatures to kill microorganisms that might still contaminate the milk.
A space probe has returned samples to earth of crystals found on a distant planet In studying these crystals scientist discovered that a 0994g sample will absorb 2027 J heat when the temperature?
