## What happens to water at 120 degrees Celsius?

As you can see, at atmospheric pressure (101,33 kPa), water boils at 100°C. To keep it liquid at 120°C, you must increase pressure to at least 200 kPa (so around 100 kPa gauge pressure). For pure water under standard atmospheric pressure, the boiling point is 100 deg C.

## Does water boil at 120 degrees in a pressure cooker?

The boiling point of a liquid increases with the increase in pressure and decreases with the decrease in pressure. … In a pressure cooker, the water boils at about 120 °C to 125 °C due to increase in pressure, as the steam is not allowed to escape out of it.

## At what pressure does water boil at 120 C?

At one atmospheric pressure, the boiling point of pure water is 100 C. In a pressure cooker, steam is not allowed to escape out. The vapour pressure on water inside the cooker becomes nearly 1.75 times the atmospheric pressure. Thus water boils at about 120C to 125 C due to increase in pressure.

## Why does water boil in a pressure cooker at 120 degree?

In a pressure cooker, water boils at about 120°C to 125°C due to increase in pressure, as the steam is not allowed to escape. The vapour pressure on the surface of the liquid inside the pressure cooker becomes nearly 1·75 times the atmospheric pressure.

## Can you boil water above 100 degrees?

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).

## What temperature water boils?

A liquid at high pressure has a higher boiling point than when that liquid is at atmospheric pressure. For example, water boils at 100 °C (212 °F) at sea level, but at 93.4 °C (200.1 °F) at 1,905 metres (6,250 ft) altitude. For a given pressure, different liquids will boil at different temperatures.

## Can water start to boil at 120 degree not 100 Justify your answer with example?

No, the water is not pure. It is because, the boiling point of pure water is 100°C but the given sample boils at 102°C. It indicates that it has some dissolved impurities.

## Why water boils faster in cooker Although the BP is not 100 but 120 degrees?

The same thing happens in a pressure cooker, but the temperature inside is much higher. … At that pressure, water boils at 121°C (250°F). That means food can cook at a much higher temperature than it ever could at atmospheric pressure—and since cooking reactions speed up at higher temperatures, your food cooks faster.

## Does water boil at a lower temperature in a pressure cooker?

A pressure cooker can be used to compensate for lower atmospheric pressure at high elevations. The boiling point of water drops by approximately 1°C per every 294 metres of altitude, causing the boiling point of water to be significantly below the 100 °C (212 °F) at standard pressure.

## What is the physical state of water at 120 degree Celsius?

Answer: It will be converted into steam.

## How do you find the boiling point of water at different pressures?

If the boiling point values for a specified substance at a specified BP temperature and pressure are given, one can determine the Boiling Point at different vapor pressure values using the Clausis-Clapeyron Equation. The Clausis-Clapeyron Equation is derived from VP2=VP1e−ΔHvRT at two different temperatures.
