What else can I help you with?
What is direct contact?
Direct contact is when something touches something else without a barrier. This is a term often used in sports like football.
What is the transfer of heat by direct contact?
When a cold object and a hot object are in direct contact (touching) heat will be transferred through thermal conduction. Normally, heat transfer processes are categorized as thermal conduction, radiative transfer or convection. Heat transfer through thermal conduction is the direct transfer of kinetic energy from one molecule to the nearby molecules. Because temperature is directly proportional to kinetic energy, interactions between neighboring particles exchange energy and that exchange energy gradually works it way from the higher temperature regions to the lower temperature regions. The process of the temperature becoming the same is called thermal equilibration. Convective heat transfer occurs in fluids. If a gas, liquid, or other fluid, changes in fluid density change the buoyancy and will cause fluid to flow (a process called convection) and the heat contained in the warmer fluid is transferred to a new location by the physical movement of the fluid. Radiative transfer occurs when a hot object radiates electromagnetic energy. While the sun is an obvious source of electromagnetic energy, it is also generated in smaller amounts by any object. The hotter objects radiate more electromagnetic energy and the cooler objects absorb it. This radiative transfer is important but not as noticeable usually as the other two. It does occur between objects whether they are in direct contact or not, but is usually so small as not to be important of the objects are touching.
What is the transfer of thermal energy from one object to another due to a difference in temperature is known as?
The transfer of thermal energy when particles of a fluid move from one place to another is convection. Temperature is a measure of how hot or cold an object is compared to a reference point.Another AnswerNo. Heat (the term, 'thermal energy', is obsolete) is defined as 'energy in transit from a warmer body to a cooler body'. So a temperature difference is necessary for heat transfer to take place.It is not heat it is convection.
What is another term used for specific heat is?
Another term used for specific heat is temperature.
What is the transfer of heat by movement of heated liquids or gases?
There are three basic heat transfer mechanisms: Conduction, Convection andRadiation. Heat transfer in opaque solids is just by Conduction. In gases andliquids all three mechanism can contribute to heat transfer.The Convection Mechanism of Heat Transfer is the transportation of heat bythe bulk motion of the fluid. If this motion is produced by buoyancy effects thatarise from the fluid having different temperatures (and so different densities) at different points, it is called Natural Convection. If the motion of the fluid is produced by a pressure gradient (like a fluid been forced to flow through a heated pipe),the heat convection mechanism is called Forced Convection Heat Transfer.
What is the term heat transfer because of direct contact?
Conduction is the term for heat transfer because of direct contact.
What is the term for heat because of direct contact?
Conduction is the term for heat transfer because of direct contact.
What is the term for heat transfer because of the?
Conduction is the term for heat transfer because of direct contact.
What is the term for heat tansfer because of direct contact?
The term for heat transfer due to direct contact is conduction. In this process, heat flows from a hotter object to a colder object when they are in direct contact with each other.
What is the term for transfer because of direct contact?
Conduction
What is the term for heart transfer because of direct contact?
Conduction
What energy is transmitted by direct contact or touch?
We apply the term conduction to the transfer of thermal energy through direct contact. The other two mechanisms that transfer thermal energy are radiation and convection.
What term describes the transfer of thermal energy between the hot plate and a teapot?
The term for the transfer of thermal energy between the hot plate and a teapot is conduction. This process occurs when heat is transferred through direct contact between objects with different temperatures.
Which way does heat transfer?
Heat can transfer through three main mechanisms: conduction (transfer through direct contact), convection (transfer through fluid motion), and radiation (transfer through electromagnetic waves). The specific method depends on the material and environment involved.
What term describes the transfer of energy between objects that have different average kinetic energies?
The transfer of energy between two objects at different average thermal kinetic energies (temperatures) is referred to as heat transfer. It is always called heat transfer, regardless of what kind of energy is being transferred.
How does heat in the atmosphere move?
Heat in the atmosphere moves through the processes of conduction, convection, and radiation. Conduction is the transfer of heat through direct contact with a surface, while convection involves the movement of air masses that carry heat energy. Radiation is the transfer of heat in the form of electromagnetic waves.
What is the term for heat transfer because of the heat of gas?
Convection is the transfer of heat through the movement of a fluid, whether liquid or gas.
