How do the principles of convection conduction and radiation explain how the water in the saucepan gets hot?
Convection: Hot water at the bottom rises, displacing cooler water, which then heats up and rises, creating a circulation that evenly distributes heat in the saucepan. Conduction: Heat is transferred directly from the stove to the saucepan, warming the metal of the saucepan which then transfers heat to the water in contact with it. Radiation: Heat from the stove is emitted as electromagnetic waves, which are absorbed by the saucepan and water, causing the molecules to vibrate and raise the temperature.
How do the principles of convention conduction and radiation explain how the water in a saucepan gets hot?
Heat conduction occurs when the stove transfers heat to the saucepan through direct contact, causing the water to heat up. Heat convection takes place as the hotter water rises to the top and cooler water sinks to the bottom, creating a circulating flow that helps heat the entire body of water. Heat radiation also plays a role, as some heat is emitted from the stove and absorbed by the water molecules, further increasing their temperature.
How do principles of convection conduction and radiation explain how the water in the saucepan gets hot?
In conduction, heat is transferred through direct contact between the heating source and the water molecules, causing the molecules to gain energy and increase in temperature. Convection occurs as the heated water molecules become less dense, rise, and are replaced by cooler water, creating a circulation that evenly distributes the heat. Radiation also contributes to heating by emitting infrared radiation from the heating source, which is absorbed by the water molecules, further increasing their kinetic energy and temperature.
How is the energy transferred from the cooker to the liquid in the saucepan?
Energy is transferred from the cooker to the liquid in the saucepan through conduction, where heat is transmitted from the hot surface of the cooker to the bottom of the saucepan by direct contact. This heat is then transferred to the liquid through convection, as the hot liquid rises and circulates, creating a convection current that heats the entire volume of liquid.
What are three ways heat can travel?
Conduction (through e.g. solid materials like metals that allow heat through - like a saucepan base) It is transformed into another object by touchConvection - in liquids and gases. Hot substances expand and so are less dense than cold substances. These less dense liquids and gases rise and cool ones fall forming a current. as an example, convector heaters in your home, the Gulf Stream that brings warm water from the Caribbean to Europe.Radiation - the method by which energy is transferred through a vacuum e.g. in the infra red heat energy from the sun as it travels across the vacuum of space.radiation, convection and conduction.

What is the conduction with a saucepan and a spoon?
It's Because of the conduction. The heat comes from the saucepan is conducted by the spoon, and when it is transferred the spoon will start heating up.
What does covering a saucepan handle with plastic help to prevent?
It prevents the conduction of heat or even conduction of electric current shock in electric saucepan.
What are some examples of heat transfer by conduction convection and radiation in everyday life?
A example of conduction is: picking up a hot bowl of soup, putting a marsh mellow over a fire, and putting ice in a HOT glass of water.Conduction: Touching a hot stove and being burned.Convection: Hot air heating/rising, cooling, and falling (same with water).Radiation: Heat from the sun warming your face.Find more examples at Yahoo Answers!
Why is energy transferred from the hob to the saucepan?
The hob transfers energy to the saucepan through conduction. When the hob is turned on, it generates heat which is transmitted to the saucepan through direct contact. This heat energy then raises the temperature of the saucepan and its contents.
Give a reason why the kettle loses less heat than the saucepan by the process of conduction?
The kettle loses less heat than the saucepan because it has a smaller surface area in contact with the surroundings, resulting in less heat transfer through conduction. Additionally, the kettle may have thicker walls which reduce heat loss through conduction compared to the thinner walls of the saucepan.
How can you draw convection?
You could draw something glowing hot, or steam rising out of a saucepan or something! x
When cooking on a stove the heat energy moves from the stove to the saucepan to the cooking food this is an example of an energy?
convection
