How is radiation and conduction alike?

Radiation and conduction are both methods of heat transfer. They both involve the movement of heat from a warmer object to a cooler one. Radiation transfers heat through electromagnetic waves, while conduction transfers heat through direct contact between objects.


Can you give me a sentence with the word conduction in it?

Conduction is the process by which heat is transferred through a material without any movement of the material itself.


How do you explain and give an example why conduction is the transfer of heat when something touches something?

Conduction is the transfer of heat through direct contact between two objects. When one object with a higher temperature comes into contact with a cooler object, heat energy is transferred from the warmer object to the cooler object. An example is when a hot pan is placed on a kitchen counter; the heat from the pan transfers to the cooler counter through conduction.


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.


Do you have to touch and object to permanently give it a charge?

No, you do not need to touch an object to permanently give it a charge. You can induce a charge on an object through methods like friction, conduction, or induction. This charge can persist on the object even after you remove your contact.
