When a kettle whistles it is because steam from the boiling water inside is escaping through a whistle on the kettle.
An externally operated valve regulating the flow of a liquid inside a pipe.

I learned what convection means in science class.
Hydrocelectomy is surgery to remove a hydrocele. A hydrocele is a fluid-filled sac inside the scrotum. A hydrocele happens when there is an opening between the belly and the scrotum.

The word you’re looking for is "whistle." A kettle whistles when the steam from the boiling liquid inside creates enough pressure to escape through a small opening, producing a distinctive sound. This auditory signal indicates that the water has reached its boiling point and is ready for use.
When a tea kettle whistles, it is because the liquid inside turns to steam and is forced by pressure through the small opening in the kettle lid. This phase change is a physical change, not a chemical one.
When a tea kettle whistles, it indicates that the water inside has reached boiling point, causing a phase change from liquid to gas. This requires energy input to break the intermolecular bonds and overcome the forces holding the water molecules together. The energy change is in the form of heat, as the water absorbs energy to transition into vapor.
Materials can come in three phases, depending on physical conditions. They are gas, liquid, and solid. If you boil a kettle of water, you are first heating up the liquid water inside the kettle. But then at boiling temperature (which is about 100 deg C or 212 deg F) the liquid in the kettle starts to turn into gas, which we call steam. As a gas, that steam rises to the surface and that's when you start to see the bubbles we call boiling. So when we "boil a kettle" we are creating steam that creates the boiling bubbles.
Copper is used for kettles because it is an excellent conductor of heat, allowing for even heating of the liquid inside the kettle. Copper also has antimicrobial properties, which helps to keep the kettle clean and free of harmful bacteria. Additionally, copper is a durable and long-lasting material, making it ideal for use in kitchenware such as kettles.
The handle of a kettle is typically made of a material that has poor thermal conductivity, such as plastic or wood. This means that it does not easily transfer heat from the hot liquid inside the kettle, making it safe to hold even when the kettle is filled with boiling water. Additionally, the shape of the handle is designed to keep it cooler and more comfortable to grip.
When a kettle boils, some of the water inside goes from the liquid state to the gaseous state and rises because it's hot. What you see on your cupboard is called condensation which happens when a gas is cooled, such as steam (gaseous water), and goes back to the liquid state, hence why you have liquid water up there.
its a liquid because its compressed and the reason that it is cold is because it has to move from liquid to gas, this movement takes energy and this energy comes from itself.
because there is liquid inside of you.
measuring jug! kettle
it is a solid because of the outside and the inside has a liquid.
Because silver teapots reflect the heat that is coming from the liquid therefore bouncing off the sides of the kettle and keeping the liquid warm. Whereas a black kettle would just absorb the heat which wouldn't keep the liquid warm. Also, silver is a bad absorber and a bad emitter.
