Hot water in a hand sink should typically be maintained at a minimum temperature of 100°F (38°C) to ensure effective handwashing and to help eliminate harmful bacteria. Some regulations may require higher temperatures, such as 110°F (43°C) or 120°F (49°C), depending on local health codes. It's essential to check specific local regulations for precise requirements.
What else can I help you with?
How your hands will feel when you place them in the container of room temperature water?
Body temperature is regulated by an intricate system called homeostasis. If the external (outside) temperature is hotter or colder than our body then various things come into play to maintain our body heat. If you put your hand into room temperature water (room temperature is generally accepted to be 20 degrees C) then it will feel cold, because body temp is about 37 degrees C. The water will absorb heat energy from your hand, making it feel cold, until the temperature of the water and the temperature of your hand are the same. Or until you decide that shoving your hand in cool water is pointless...If you put your hand into water that is at 37 degrees C then you won't notice any temperature difference. It just feels wet. It's really weird, try it!
Why does hand sanitizer get warm when mixed with water?
When hand sanitizer is mixed with water, it undergoes a process called dilution. This dilution can cause the temperature to increase due to the chemical reaction between the alcohol in the hand sanitizer and the water molecules. As the alcohol evaporates, it releases heat energy, resulting in a warming sensation.
What liquid boils in your hand?
No liquid will boil in your hand because the temperature of your hand is not high enough to cause a liquid to boil. Boiling occurs when a liquid reaches its boiling point temperature, which is much higher than normal body temperature.
Without a thermometer how can you determine water temperature of 100 degrees F?
You can use the hand method to estimate water temperature. Placing your hand in the water, if it feels hot to the touch but not scalding, it could be around 100 degrees F. Additionally, you can observe the water to see if steam is rising steadily, which typically occurs at around 100 degrees F.
What is a liquid at room temperature and at negative 100 degrees Celsius?
At room temperature, a common liquid is water, which remains in its liquid state up to 100 degrees Celsius. However, at negative 100 degrees Celsius, many substances solidify, including water. Liquid methane, on the other hand, exists as a liquid at room temperature (around -161 degrees Celsius) and remains liquid well below -100 degrees Celsius, making it a suitable example.
Why does your hand feel cool if you wash with water?
The temperature differences - if the water temperature is cooler than the temperature of your hand, your hand will lose heat to the water. Furthermore, when the remaining droplets of water on your hand evaporate, it will also take some of the heat it absorbed from your hand.
Why does your hand feel cool if you wash it with water?

Why you cannot check your temperature with your own hand but another person can?
because our temperature is the same body temperature but another persons are different
What is difference in steam and frost?
Steam is water vapor that forms when water is boiled or heated to a high temperature. Frost, on the other hand, is the thin layer of ice crystals that forms on surfaces that are below freezing temperature, typically early in the morning or late at night.
How does air temperature affect air temperature?
Air temperature greatly affects water temperature. When the sun is strong, it increases the temperature of the air and water. On the other hand, when the sun is less intense, the temperature of the air and water decreases.
Can a hen overheat her eggs?
No, the eggs and the hen kind of go hand in hand. A chickens body temperature is 101-102ºF. That happens to also be the temperature that the eggs need to incubate at. Since the chicken cannot warm the eggs to a higher temperature than she is, the hen herself cannot overheat the eggs.

Why does your hand feel cold when you you wash it with water?
The temperature of the water is lower than the air temperature. [Try running the hot water a little before you wash your hands.]
What is the proper water temperature for hand washing?
For hand washing, the water should be between 100 and 110 degrees Fahrenheidt - noticeably hot but not scalding.
Liquid water can change to water vapor through boiling or?
evaporation. Boiling occurs when water reaches its boiling point temperature, causing rapid vaporization throughout the liquid. Evaporation, on the other hand, is the slow vaporization of water at temperatures below its boiling point, occurring at the surface of the liquid.
When you put one hand in hot water and one in cold water then both in tap water what do you expect to feel why?
It depends on the temperature of the tap water.
What should the hot water temperature be on a hand wash sink?
Hot Water Temp can be till 45 deg C
