The hot plate's temperature is higher than 100°C. That is why the 'steam bubbles' form at the bottom of the pan, then float up to the top. All of the water surrounding the jar is at 100°C. As soon as a quantity of water turns to steam, it's bubble rises to the surface and is released into the surrounding air. The water that's touching the jar has not yet boiled, so it has less than enough energy to cause the water inside the jar to boil.

How can we get maximum angle of 90 degrees in RC phase shift oscillators?
To achieve a maximum phase shift of 90 degrees in RC phase shift oscillators, you can use a combination of three RC stages in series, where each stage contributes 60 degrees of phase shift at the desired frequency. By carefully selecting the resistor and capacitor values to ensure that the total phase shift across the three stages reaches 180 degrees, you can then use a phase inverter, such as a transistor or an op-amp, to provide the additional 180 degrees needed for positive feedback. This setup ensures that the oscillator can sustain oscillations at the desired frequency.
When a conductor is rotated in a magnetic field at what point in the cycle is emf at maximum amplitude?
When a conductor is rotated in a magnetic field, the electromotive force (emf) reaches its maximum amplitude when the plane of the conductor is perpendicular to the magnetic field lines. At this point, the rate of change of magnetic flux through the conductor is highest, leading to the maximum induced emf according to Faraday's law of electromagnetic induction. This occurs twice during each complete rotation, specifically at 90 degrees and 270 degrees of the rotation cycle.
What is steam injection molding?
Steam injection molding is also referred to as RHCM. Rapid Heat Cycle Molding. In general ABS material is used as the raw material. The primary advantage of steam injection is that it eliminates weld-lines on molded parts. This allows companies to eliminate future processes such as painting from the production process. In non steam molding, water will heat the tool to a constant temperature (say 60 degrees). Plastic will be injected to the warm tool. In steam molding, steam is injected at 160 degrees to heat the tool. When the tool reaches a predetermined temperature (about 140 degrees) the plastic is injected. Cold water is immediately added to the process to cool the plastic down to around 40 degrees. Because the mold is so hot when the plastic is injected, there are no weld lines & you should end up with a 'perfect' product. Steam injection molding is now being extensively used to produce the front covers of LCD TVs.
How do you mix 4.5 parts cement to 1 part water?
To mix 4.5 parts cement to 1 part water, first measure out the cement and water using a consistent unit, such as cups or pounds. For every 4.5 units of cement, use 1 unit of water. Combine the cement and water in a mixing container, then stir thoroughly until the mixture reaches a uniform, workable consistency. Adjust the water slightly if needed, but avoid adding too much, as it can weaken the mix.
How do you handle hydraulic torque wrench on fastening bolts?
When it comes to tightening bolts, there is a specific measure for bolts. You need to go through the manual. There is a spring laid in the handle as when the wrench reaches the particular limit, that could bend proportionally. Thus, the worker should stop when it reaches the particular limit.
How many degrees does 936F have to drop before it reaches boiling point?

Will boiling water reach 160 degrees?
No, boiling water reaches a temperature of 212 degrees Fahrenheit (100 degrees Celsius) at standard atmospheric pressure.
How do you know when water is boiling?
Water is boiling when it reaches a temperature of 212 degrees Fahrenheit (100 degrees Celsius) and starts to produce bubbles and steam.
What is considered boiling water and at what temperature does it occur?
Boiling water is when water reaches a temperature of 212 degrees Fahrenheit (100 degrees Celsius) at sea level.
When is water considered boiling?
Water is considered boiling when it reaches a temperature of 212 degrees Fahrenheit or 100 degrees Celsius, causing it to turn into steam or vapor.
What are the temperatures for boiling water?
The boiling point of water is 100 degree celsius
How can you determine if water is boiling?
Water is boiling when it reaches a temperature of 212 degrees Fahrenheit (100 degrees Celsius) at sea level. You can tell water is boiling by seeing bubbles forming and rising to the surface.
How can you determine when water is boiling?
Water is boiling when it reaches a temperature of 212 degrees Fahrenheit (100 degrees Celsius) at sea level. You can tell water is boiling when you see bubbles forming and rising to the surface.
When you heat water to 100 degrees Celsius it?
reaches its boiling point and starts to vaporize, turning into steam.
What would happen to a sample of water at 30 degrees c if it is heated until the temperature reaches 120 degrees c?
The water would first heat up and reach its boiling point at 100 degrees Celsius. Once it reaches 100 degrees Celsius, it would start boiling and convert into steam at a constant temperature of 100 degrees Celsius until all the water has evaporated.
What process is water boiling?
Water boiling is the process where water reaches its boiling point (100 degrees Celsius or 212 degrees Fahrenheit) and transitions from a liquid to a gas. This transition is accompanied by the formation of bubbles as the water vaporizes.
When does Boiling temperature Start?
Boiling temperature starts when the liquid reaches its boiling point, which is the temperature at which its vapor pressure equals atmospheric pressure. At this point, the liquid begins to vaporize and turn into a gas.
