# What evidence can you cite for the claim that water can boil at a temperature of 0 C?

Contents

Evidence that water can boil at a temperature of 0°C? Ice will form in boiling water in a vacuum chamber. Pressure is greatly reduced, water starts to boil. Continued boiling results in lowered temperature, and lower boiling point.

## Is it the boiling of water or the higher temperature of water that cooks food faster in a pressure cooker?

The trapped steam increases the atmospheric pressure inside the cooker by 15 pounds per square inch (psi), or 15 pounds above normal sea-level pressure. At that pressure, the boiling point of water is increased from 212°F to 250°F. This higher temperature is what cooks food faster.

## When water is boiled What can you say about its temperature?

Explanation: Heat necessary to covert 1 gram of a liquid substance into gaseous state at its boiling point without changing the temperature is known as latent heat of vaporization. Therefore, it is known that water boils at 100 degree celsius and its temperature remains constant till the water is boiling.

## Why doesn’t the water at the bottom of a geyser boil when it is at 100 C?

Why doesn’t the water at the bottom of a geyser boil when it is at 100 C? Because of the immense pressure at the bottom of the ocean is unable to turn to gas so does not actually boil.

## Why does increasing the temperature of a solid make it melt?

Why does increasing the temperature of a solid make it melt? Increasing the temperature increases molecular vibrations until attractive forces can no longer hold the molecules in one place. … Cooling slows molecular motion until attractive forces between molecules can hold them in place.

## What would happen to the temperature of boiling water if you added energy?

For instance, when water is boiling, adding heat does not increase its temperature. … This happens at the boiling temperature of every substance that can vaporize. At the boiling temperature, adding heat energy converts the liquid into a gas WITHOUT RAISING THE TEMPERATURE.

## Does the temperature of the water rise while it is boiling quizlet?

The temperature of water rises as it gets to the boiling point. Once the water gets to the boiling point, the temperature remains constant (keeps potential energy). Heat is still transferred to change the bonding between molecules.

## When water boils or freezes during these processes its temperature?

On the Fahrenheit scale, water freezes at 32° and boils at 212°. In the United States, forecast temperatures measured in Fahrenheit rarely go below -20° or above 120°.

## When water boils or freezes during these process it’s temperature?

Water boils and freezes exactly at 100ºC and 0ºC respectively; find the reason for it from the following.

## What happens when water boils chemistry?

When water is boiled, the heat energy is transferred to the molecules of water, which begin to move more quickly. Eventually, the molecules have too much energy to stay connected as a liquid. When this occurs, they form gaseous molecules of water vapor, which float to the surface as bubbles and travel into the air.

## What happens to the water pressure at the bottom of a geyser when some of the water above gushes out?

What happens to the water pressure at the bottom of a geyser when some of the water above gushes on? As water gushed out, the pressure on the remaining water is reduced; the water boils rapidly and erupts with great force. Afterwards, the geyser refills and repeats the cycle.

## Can a sample of water possibly have the same volume after being warmed by several Celsius degrees?

water expands when freezing. Can a sample of water possibly have the same volume after being warmed by several Celsius degrees? less than 30 degrees C. They both have to equal the same temperature by the end of the heat transfer.

## What are four common phases of matter?

There are four natural states of matter: Solids, liquids, gases and plasma. The fifth state is the man-made Bose-Einstein condensates. In a solid, particles are packed tightly together so they don’t move much.

## What happens when a solid changes to a liquid?

Melting occurs when a solid is heated and turns to liquid. The particles in a solid gain enough energy to overcome the bonding forces holding them firmly in place. Typically, during melting, the particles start to move about, staying close to their neighbouring particles, then move more freely.

## What happens when a solid melts into a liquid?

When a solid is heated the particles gain energy and start to vibrate faster and faster. … Although the particles are still loosely connected they are able to move around. At this point the solid is melting to form a liquid. The particles in the liquid are the same as in the solid but they have more energy.

## What happened to liquid water when heated?

Evaporation happens when a liquid substance becomes a gas. When water is heated, it evaporates. The molecules move and vibrate so quickly that they escape into the atmosphere as molecules of water vapor. … Water is evaporating, but staying in the air as a vapor.
