When a liquid boils, its temperature remains constant because the heat energy supplied is used for the phase transition from liquid to gas, rather than raising the temperature. This energy, known as the heat of vaporization, breaks the intermolecular bonds in the liquid, allowing molecules to escape into the gas phase. As a result, while the temperature stays steady, the added heat facilitates the transformation rather than increasing temperature.
When water boils, the temperature remains constant at 100°C (at standard atmospheric pressure) because the added heat energy is used for the phase change from liquid to vapor rather than increasing the temperature. This energy is called the latent heat of vaporization. As heat is absorbed, water molecules gain enough energy to break free from the liquid state and enter the gaseous state, allowing the boiling process to occur without a rise in temperature.
First you can not add a cold temperature to anything. Ask your teacher to explain what heat is an what temperature is, because you clearly do not understand this. When a liquid BOILS - it turns into gas. When a liquid FREEZES - it turn into a solid.
Using a pot with a wider surface area and a lid can help liquids boil faster by allowing more heat to be transferred to the liquid. Additionally, increasing the temperature of the heat source can speed up the boiling process.
The temperature. A liquid will increase in temperature until it reaches the boiling point temperature. At this temperature the liquid will become a gas. Under normal circumstances, the liquid cannot get any hotter than the boiling point without becoming a gas. So the liquid remains the same temperature until it has all boiled away.
When water boils at 212 degrees Fahrenheit (100 degrees Celsius), it absorbs latent heat, specifically the latent heat of vaporization. This energy is required to break the intermolecular bonds between water molecules, allowing them to transition from the liquid phase to the gas phase. While the temperature remains constant during boiling, the absorbed energy does not increase the water's temperature but facilitates this phase change. Thus, at boiling point, water is indeed primarily absorbing latent heat.
No. Take water for example. Water boils at 100 degrees C. When water boils it becomes steam. This steam as soon as it is released is 100 degrees C also. The boiling point for a liquid is the point when it becomes a gas.
You're measuring the boiling point of the liquid.
a solid melts (and the liquid remains at the temperature of the solid).

A temperature at which internal pressure become equal to atmospheric pressure is called boiling pointAt boiling point kinetic energy of liquid molecules remains constant ,although heat is continously supplied that is why boiling point of a liquid remains constant.
The water has already reached the 212 degree boiling point. At 212 degrees the water can exist as either a liquid or a vapor. Absorbing the latent heat pushes liquid to the vapor state without any change in temperature.

False. When water reaches 212 degrees Fahrenheit (100 degrees Celsius) and boils, it is absorbing both sensible heat (temperature increase) and latent heat (phase change from liquid to gas).
When heat is applied to a solid, its temperature rises until it reaches the melting point of the substance. As the heat application continues, the temperature remains constant at the melting point as all of the heat is consumed in changing the state of the substance from solid to liquid. It is only after the conversion to liquid is complete that the temperature of the substance again starts to rise as long as heat is still being applied.
The boiling point temperature remains constant because liquids evaporate at this point. If the temperature drops the liquid will no longer boil. At a higher temperature the vapor becomes hotter, not the liquid.
Orange boils at the temperature of 212 degrees Fahrenheit. This is the same temperature that water boils at.
