What is the method of transfer that does not require contact?
One method of transfer that does not require contact is through radiation. Radiation is the transfer of energy in the form of electromagnetic waves, such as light or heat, without the need for physical contact between objects.
Does conduction require direct contact between objects objects have to be touching?
Yes, conduction does require direct contact between objects for heat transfer to occur. This is because heat is transferred through the collision of particles in direct contact with each other. If there is no direct contact, conduction cannot take place.
What is the process that involves the transfer of heat directly between two objects in contact?
The process that involves the transfer of heat directly between two objects in contact is called conduction.
Which types of heat transfer invlove heat flow from objects to colder objects?
Conduction, convection, and radiation are all types of heat transfer that involve heat flow from objects to colder objects. Conduction is the transfer of heat through a material due to direct contact, convection is the transfer of heat through a fluid (liquid or gas), and radiation is the transfer of heat through electromagnetic waves.
A process of heat transfer that occurs when two objects are in contact with each other is?
Conduction is the process of heat transfer that occurs when two objects are in contact with each other. Heat travels from the warmer object to the cooler object through direct contact between the molecules of the two objects.
What is the method of heat transfer does not require a medium?
Radiation is the method of heat transfer that does not require a medium. Energy is transferred in the form of electromagnetic waves, such as light or infrared radiation, through empty space. This type of heat transfer can occur between objects that are not in direct contact with each other.
Were transfer of heat between objects that are in contact?
This is referred to as conduction, where heat is transferred through direct contact between objects. It occurs when vibrating molecules in a warmer object transfer energy to neighboring molecules in a cooler object. Temperature difference between the objects drives this heat transfer process.
What happens when two objects at the same temperature are in contact?
When two objects at the same temperature are in contact, no heat will transfer between them as there is no temperature difference driving the heat transfer. This is known as thermal equilibrium, where the objects reach a balance in their thermal energies.
What is meant by conduction heat transfer?
Conduction heat transfer refers to the process of heat transfer between two objects or regions in direct contact with each other. This transfer occurs due to the collision and transfer of energy between the molecules of the objects. It relies on the physical contact and proximity of the objects for heat to be conducted from the hotter object to the cooler one.
What is the energy transfer process that does not require the presence of molecules to transfer heat?
Radiation is the energy transfer process that does not require the presence of molecules to transfer heat. It can occur through empty space and does not require a medium to carry the heat. Examples include heat transfer from the sun to the Earth and infrared radiation emitted by objects.
When two objects are touching and transfer heat is called what?
When two objects are touching and transfer heat, it is called conduction. Conduction is the transfer of heat energy through direct contact between particles of different temperatures.
Can heat only be transferred by radiation if the objects are touching?
Heat can be transferred by radiation even if the objects are not touching. Radiation is a form of energy transfer that can occur through empty space, so it does not require direct contact between objects. Objects can exchange heat through radiation by emitting and absorbing electromagnetic waves.
