Is 102.56 degree celsius a high temperature?
In terms of hot to touch, yes, very high.In terms of the heat it takes to melt a metal, no, it is not very high
What does a low U-value mean?
It can also be referred to as an 'overall heat transfer co-efficient' and measures how well parts of a building transfer heat. This means that the higher the U value the worse the thermal performance of the building envelope. A low U value usually indicates high levels of insulation.
What are u-values?
A U value is a measure of heat loss in a building element such as a wall, floor or roof. It can also be referred to as an 'overall heat transfer co-efficient' and measures how well parts of a building transfer heat. This means that the higher the U value the worse the thermal performance of the building envelope. A low U value usually indicates high levels of insulation. They are useful as it is a way of predicting the composite behaviour of an entire building element rather than relying on the properties of individual materials. By Andreea Teodora Merlan
What do plus and minus temperature signify?
Its signifies that the temperature maybe high or low ..
What is the difference between triangular and square pitch in evaporators?
Square pitch is used in HEX and condensers when a fluid that is prone to fouling is flowing through the shell side. Square pitch allows for easier cleaning but the heat transfer isn't as high as triangular pitch because less tubes can be placed. If you don't have a fluid that is prone to fouling (adding layers of junk to the tubes) you can use triangular which allows you to place more tubes in the HEX so higher heat transfer.
Can heat transfer from one object to with the same temperature?
Yes, heat can transfer between objects with the same temperature. However, there will be no net transfer of heat because the objects are already in thermal equilibrium.
How would it be possible that there could be high temperature but no heat transfer?
High temperature doesn't necessarily indicate heat transfer if the surrounding environment is at a similar or lower temperature. Heat transfer occurs when there is a temperature difference between objects, causing energy to move from a higher temperature object to a lower temperature one. If the surroundings are not significantly cooler, there may be high temperature but minimal heat transfer.
What happens when there is a temperature difference two objects?
Temperature is a measure of the heat energy of objects, and heat is the energy transferred from a high temperature location to a low temperature location.When two objects are in contact, heat always flows from the warmer object to the cooler object by conduction, until thermal equilibrium is established and the heat transfer stops (becomes the same in either direction). The transfer of heat continues as long as there is a difference in temperature between the two points.
What is the energy that flows between 2 objects due to a difference in temperature?
The energy that flows between two objects due to a difference in temperature is called heat. Heat transfer occurs from a high temperature object to a low temperature object until thermal equilibrium is reached.
What is energy that is transferred to an object at a high temperature to an object at a low temperature?
Heat is the energy that is transferred from an object at a high temperature to an object at a low temperature. This transfer of heat occurs in order to reach thermal equilibrium, where both objects eventually have the same temperature.
What happens when there's a temperature difference between two objects?
Temperature is a measure of the heat energy of objects, and heat is the energy transferred from a high temperature location to a low temperature location.When two objects are in contact, heat always flows from the warmer object to the cooler object by conduction, until thermal equilibrium is established and the heat transfer stops (becomes the same in either direction). The transfer of heat continues as long as there is a difference in temperature between the two points.

Does the change in temperature of an object affect how much heat it can transfer to another object?
Yes, the change in temperature of an object does affect how much heat it can transfer to another object. The heat transfer rate is directly proportional to the temperature difference between the two objects according to the formula for heat transfer, Q = mcΔT, where Q is the heat transferred, m is the mass of the object, c is the specific heat capacity of the material, and ΔT is the change in temperature.
Does heat transfer by burning?
yes,because heat has a high temperature
Heat energy travels from an object with a high?
Heat energy travels from an object with a high temperature to an object with a low temperature in order to achieve thermal equilibrium. This transfer of heat occurs through conduction, convection, or radiation depending on the specific scenario.

Temperature is a measure of the heat energy of objects, and heat is the energy transferred from a high temperature location to a low temperature location.When two objects are in contact, heat always flows from the warmer object to the cooler object by conduction, until thermal equilibrium is established and the heat transfer stops (becomes the same in either direction). The transfer of heat continues as long as there is a difference in temperature between the two points.
Why do heat gives heat than cold temperature?
Heat transfer occurs from a higher temperature to a lower temperature, following the principle of the second law of thermodynamics. When two objects of different temperatures come into contact, heat will flow from the warmer object to the cooler one, until they reach thermal equilibrium. This is why heat "gives" heat to colder temperatures.
