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.

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!
