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 Heat (the term, 'thermal energy', is obsolete) is defined as 'energy in transit from a warmer body to a cooler body'.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 effect if any does this energy transfer have on the overall efficiency of the car engine?
As a "heat engine", a car engine must rid itself of heat to continue. Efficiency of the heat engine depends on the difference in temperature; therefore, as the temperature outside reaches the temperature inside, the engine stops.
What is the effect of temperature change to the amount of heat content of the substance?
The effect of temperature change to the amount of heat content of the substance is called heat transfer. As heat increases, the temperature decreases.
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.
Which type of energy transfer occurs when water is heated on a hot plate?
It is called conduction. The molecules vibrate and the energy transferred between molecules from a high temperature area to a low temperature area.
How does temperature affect the rate of heat transfer?
For conductive and convective heat transfer, the rate of heat transfer is proportional to the the temperature difference; if you double the difference you will double the rate of heat transfer. For radiative heat transfer, the rate of heat transfer is proportional to the difference of the 4th powers of the absolute temperatures.
How would it be possible that there could be high temperature but no heat transfer?
Heat transfer will only occur if there is a difference in temperatures. So if an object is high temperature but the surrounding area is also high temperature there will be no heat transfer.
Heat is the transfer of thermal energy because of difference?
Heat is not the transfer of thermal energy. Heat is the thermal energy. What drives itacross a boundary between substances or objects is a difference in their temperatures.
Does the change in temperature of an object affect how much heat it can transfer to another object?
The temperature of an object affects how much heat can be transferred. This is because if the object to which heat is transferred has high temperature then there will not be much heat transfer. Heat flows from a body of higher temperature to lower temperature.
Where can heat transfer happen?
any where but condition is there should be temperature difference
Describe the condition that must exist for transfer of heat to occur?
For heat transfer to occur, there must be a temperature difference between the two objects or systems involved. Heat always flows from a higher temperature to a lower temperature until thermal equilibrium is reached.
Why is energy transferred as heat between two objects at the same temperature?
It's not. A difference in temperature is required in order to drive the transfer of heat.
What is the reason for heat transfer from one substance to another difference in mass?
Difference in temperature is the reason heat transfers from one substance to another.
Transfer of energy from one object to another as a result of difference in temperature?
Heat energy.
At what speed does heat radiation travel?
Heat transfer rate in radiation is proportional to the fourth power of the temperature difference
What is the difference between heat transfer and mass transfer?
Heat transfer deals with the movement of heat and temperature gradients. The three types of heat transfer are conduction, convection, and radiation. Mass transfer deals with concentrations of a particular substance. Types of mass transfer include diffusion and convection.
conclusion and recommendation of lab heat transfer of first law termodynamics?
Conclusion The lab experiment on heat transfer of first law thermodynamics has demonstrated that heat energy can be transferred from one body to another through conduction, convection, and radiation. The data collected in this experiment shows that the rate of heat transfer is determined by the thermal conductivity of the material, the surface area of the material, and the temperature difference between the materials. The results of the experiment suggest that the higher the thermal conductivity of the material, the greater the rate of heat transfer. In addition, the higher the temperature difference between the two materials, the more heat will be transferred. Furthermore, the larger the surface area of the material, the greater the rate of heat transfer. Recommendation This lab experiment has shown that heat transfer is a complex process and can be further explored by performing more experiments with different materials and different temperature differences. In addition, this experiment has shown that the factors which affect heat transfer, such as thermal conductivity and surface area, can be manipulated to increase or decrease the rate of heat transfer. Therefore, it is recommended that further experiments should be conducted in order to further understand how these factors interact to affect the rate of heat transfer. Additionally, it is recommended that experiments should be conducted to explore how different materials and different temperature differences affect the rate of heat transfer. Finally, it is recommended that experiments should be conducted to explore how different materials and different surface areas affect the rate of heat transfer.
