# What is the maximum temperature boiling water can reach?

Contents

Superheated water is liquid water under pressure at temperatures between the usual boiling point, 100 °C (212 °F) and the critical temperature, 374 °C (705 °F).

## Does boiling water go above 212 degrees?

Above 212°F at standard pressure, liquid water is unstable. … in it, this boiling process doesn’t happen until the temperature is significantly above 212°F, so you can temporarily have liquid water (called ‘superheated’) above that boiling point.

## What temperature of hot water will kill you?

A water temperature of 120°F does not kill the Legionella bacteria; a hot water temperature of 140°F is required at which Legionellae dies in 32 minutes.

## Is boiling the maximum temperature a substance can reach?

Boiling is the maximum temperature a substance can reach. It is the maximum temperature of the liquid phase of the substance but not the gaseous one! … When temperature at boiling remains constant, something is “wrong”.

## Can Steam be hotter than 100 degrees?

Since it is a kettle on your stove the pressure is atmospheric. The water transitions to saturated vapor (steam) at 100 C, so unless the pressure changes, the steam will also be 100 C. If the pressure is increased, you can get superheated vapor (i.e. superheated steam) that is greater than 100 C.

## Can boiling water go above 100?

Water Hotter Than Boiling Point and Colder Than Freezing Point. Liquid water can be hotter than 100 °C (212 °F) and colder than 0 °C (32 °F). Heating water above its boiling point without boiling is called superheating. If water is superheated, it can exceed its boiling point without boiling.

## What happens to water under extreme pressure?

As pressure increases, a few minor effects will happen: Water’ll lose some volume (though it’s not too compressible). Heat’ll get generated (though it’ll be lost to the heat bath). The chemical equilibrium will shift a bit.

## Can you die if you stay in hot water too long?

Sitting in hot water for a long time can cause severe heat-related illnesses, such as nausea, dizziness or fainting, and even death. Avoid staying in the hot tub for more than 10 minutes at one time.

## Can you die in 150 degree water?

Each year, approximately 3,800 injuries and 34 deaths occur in the home due to scalding from excessively hot tap water. The majority of these accidents involve the elderly and children under the age of five. … Most adults will suffer third-degree burns if exposed to 150 degree water for two seconds.

## Does hot water get rid of germs?

Hot water kills germs, though it has to be very hot

According to WHO, temperatures of 140°F to 150°F are enough to kill most viruses, and boiling water makes it safe from pathogens like bacteria, viruses, and protozoa.

## What happened to the temperature of water while it is boiling?

Temperature of a substance during its phase change remains constant. Hence when water boils, the temperature of water remains constant i.e 100oC.

## What’s the highest water temperature?

Superheated water is liquid water under pressure at temperatures between the usual boiling point, 100 °C (212 °F) and the critical temperature, 374 °C (705 °F).

## Is steaming quicker than boiling?

Steaming is faster than boiling. Steaming is far more energy- and time-efficient than boiling. … boiling because most of you are wasting your time, waiting for a big pot of water to boil while your hungry family sits growing more famished.

## What is hotter boiling water or steam?

Steam occurs when water goes above 212 degrees Fahrenheit, which is hotter than water when it is at its stable point. While water boils at 212 F, steam is at a much higher temperature as water turns to vapor. … The instability of the liquid can make it turn into a vapor more quickly and can produce steam.

## How hot can steam get under pressure?

Example: The temperature of 250 psig pure steam is always 406°F. Heat of Saturated Liquid (Column 4). This is the amount of heat required to raise the temperature of a pound of water from 32°F to the boiling point at the pressure and temperature shown. It is expressed in British thermal units (Btu).
