How is conduction heat transferred between hot and cold objects?
Wiki User
∙ 10y ago
Conduction of heat means that two objects with different temperatures are touching each other. The heat of the hotter object generally transfers to the cooler object. In the hotter object, molecules are moving faster. The vibration from these molecules causes the molecules in the cooler object to vibrate faster, which translates into heat.

How is energy transferred when an instant cold pack is put on muscle injury?
Heat energy is transferred by conduction from the muscle to the cold pack.
How heat is transferred between a hot and a cold object by conduction?
because when something hot touches something cold the heat touches the surface of the cold thing making it burn and spread the heat around making it warm.
The greatest amount of heat energy transferred between the hot and cold water is transferred by the process of?
absorption
Describe how the heat from the stove gets to the water in the pot?
As the stove heats up the pot, heat is transferred from the pot to the water through conduction. Within the pot, heat is transferred through convection from the hot water molecules to the cold ones.
Do heat and cold flow between objects?
Technically the answer to your question is no. Heat does indeed flow between objects, but cold does not because it doesn't really physically exist. "Cold" is just a lower level of heat.

what are adventage and disadvantage conduction?
Advantages of Conduction: Conduction is the most efficient way to transfer heat. Heat is transferred directly from the hot object to the cold object, so it can happen quickly and with minimal energy loss. Conduction requires no external force or energy to facilitate the transfer of heat. This makes it a cost-effective option for applications that require the transfer of heat from one object to another. Conduction is a simple and straightforward process. It does not require complex machinery or advanced technology to be effective. Because conduction does not require any external force, it can happen in any environment. This makes it a viable option for applications in remote or hostile environments. Disadvantages of Conduction: Conduction is a relatively slow process. Heat can take a long time to transfer from one object to another, especially if there is a large temperature difference between the two objects. Conduction can be impeded by materials that are good insulators. This can reduce the efficiency of the process and result in a longer transfer time. Conduction can only transfer heat from a hot object to a cold object. It cannot transfer heat from one cold object to another cold object. Conduction can be inefficient in certain applications. If the two objects are not in direct contact, the heat transfer rate can be significantly reduced.
What happens to hot and cold objects when they brought together?
If heat can flow between them, then heat flows from the hot one to the cold one. The temperature of the hot object falls, and the temperature of the cold object rises. What drives the transfer of heat is the difference in temperature, so as soon as both objects are at the same temperature, the process stops, and no more heat is transferred.

What is heat transfered from a cold object to a warm one?
Heat is a measure of how quickly the atoms of an object are vibrating. When a warm object touches a cooler object, the vibrating atoms from the warm object cause the atoms of the cooler object to vibrate more, and thus become warmer. There are three main ways of heat transfer conduction convection and radiation.
Is body heat convection heat?
Yep, the heat is transferred via convection when fluid flow is involved, which is primarily blood flow. For example, you hands are cold, then warm blood flow helps to warm them up. That's convection. Sure conduction is also involved. When heat must pass solid barrier such as cell walls then the heat is transferred via conduction.
Can heat transfer between gas and solid through conduction?
Definitely. I never thought of this before you asked, but that's exactly the reason why you must not put your tongue on the pump handle in Minnesota in January ... because so much heat has transferred out of the solid pump handle into the cold air, that the metal has become dangerously cold.
The transfer of heat between two objects touching is called?
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.
