Water boils at a lower temperature under higher pressure, and at the depths of the ocean where pressures are extremely high, the boiling point of water is raised above the temperature of the surrounding environment. This prevents the water from boiling despite the high temperatures present at those depths.
Boiling point is a physical property of a substance, as it is a characteristic of the substance that remains constant despite changes in its physical state. When a substance reaches its boiling point, it changes from a liquid to a gas through the physical process of boiling.
The skin helps regulate body temperature through the processes of sweating, which cools the body as it evaporates, and vasoconstriction or vasodilation of blood vessels to adjust heat loss or retention. This helps maintain homeostasis by keeping the body's internal temperature within a narrow range despite external temperature fluctuations.
Birds and mammals are examples of homeotherms because they can regulate their body temperature internally, maintaining a relatively constant temperature despite changes in their external environment.
An iceberg contains a larger amount of thermal energy (heat) due to its overall mass and temperature, despite being at a lower temperature than boiling water. The boiling water loses energy continuously through evaporation, so it contains less overall thermal energy than the iceberg.
They are both phase changes, this means that until the melting or boiling are complete the temperature of the system remains at the melting or boiling point, despite the continued input of heat energy.

Some signs that a liquid has reached its boiling point include the appearance of bubbles rising to the surface of the liquid, the liquid vigorously boiling and producing steam, and a temperature plateau where the liquid remains at a constant temperature despite continued heating.
increases gradually until it reaches the boiling point at 100 degrees Celsius. At this point, the temperature remains constant despite continued heating until all the water has evaporated.

Nitrogen has a low boiling point of -196 degrees Celsius, which is why it is a gas at room temperature despite being very cold. It remains a gas because it does not reach its boiling point under normal atmospheric conditions.

The temperature remains constant during a phase change (e.g., boiling or melting) as the added heat is used to break intermolecular bonds rather than increase the temperature. Once the phase change is complete, the temperature will start to rise again.
The solid layer could be maintained through a process called supercooling, where the substance remains in a liquid state below its freezing point due to the absence of nucleation sites for solid crystal formation. Another possibility is that the layer is composed of a material with a high melting point that requires an extremely high temperature to melt, thus appearing solid despite the heat.
