# How hot is boiling water?

Contents

This conversion of liquid water to water vapor (steam) is what you see when you’re looking at a pot of boiling water. As we all know, for pure water at standard pressure (the air pressure that exists at sea level), the temperature at which this occurs is 212°F (100°C).

## What is the usual temperature of boiling water?

The boiling point of a liquid varies according to the applied pressure; the normal boiling point is the temperature at which the vapour pressure is equal to the standard sea-level atmospheric pressure (760 mm [29.92 inches] of mercury). At sea level, water boils at 100° C (212° F).

## What is the temperature of boiling water after 10 minutes?

After boiling a cup of water, I recorded its temperature every minute for thirty minutes. The data is graphed below, with the independent variable as time in minutes and the dependent variable as temperature.

Time Temperature
8 151
9 148
10 145
11 142

## Does water boil at 99 degrees?

Water boils at sea level at 100 degrees Celsius. Not 99 degrees, but 100 degrees. It has to reach its potential for water to boil.

## What temperature does water boil at feet?

Boiling point of pure water at elevated altitudes

Altitude, ft (m) Boiling point of water, °F (°C)
0 (0 m) 212°F (100°C)
500 (150 m) 211.1°F (99.5°C)
1,000 (305 m) 210.2°F (99°C)
2,000 (610 m) 208.4°F (98°C)

## Is 60 degrees water hot?

In general, hot water is 130 F (54.4 C) or above. Warm water is between 110 and 90 F (43.3 to 32.2 C). Cold water is generally between 80 and 60 F (26.7 to 15 C).

## Is 100 degree water hot?

Depending on the source, you will find differing opinions on what temperature range constitutes lukewarm water. Some references say it is between 100 and 110 F (36.5 to 40.5 C). … Run the water over your wrist and if it feels warmer than your body temperature, but not hot, that should be just about right.

## Is 120 degree water hot?

The EPA recommends 120 degrees because it’s hot enough to keep diseases at bay, it’s not hot enough to cause scalding, it will supply enough hot water for most small families and is relatively energy-efficient.

## What would happen to the boiling point of water at 8000?

At sea level, water boils at 100 °C (212 °F). For every 152.4-metre (500 ft) increase in elevation, water’s boiling point is lowered by approximately 0.5 °C. At 2,438.4 metres (8,000 ft) in elevation, water boils at just 92 °C (198 °F).

## Does water boil at 96 degrees?

High Altitude: Water boils at less than 212 degrees F. (approximately 96 degrees F.). … Sea Level: Water boils at 212 degrees F. and simmers at 190 degrees F.

THIS IS FUN:  Can you eat a baked potato that's been sitting out overnight?

## Does water boil at 90C?

The temperature at which the saturation vapour pressure of water is 700mb is about 90C, so water will boil at 90C at the summit of a 10,000ft mountain. It works the other way as well, if the atmospheric pressure is higher than the standard atmospheric pressure, water will boil at a higher temperature.
