The surface area, again, is controlled by the design and manufacture of the exchanger. The more tubes contained in the bundle, the greater the surface area. The tube length will also affect heat transfer, as will the outside diameter and metal thickness of the tubes.
Yes, temperature difference does affect heat transfer rate. The greater the temperature difference between two objects, the faster heat will transfer between them. This is described by Newton's Law of Cooling, where the rate of heat transfer is directly proportional to the temperature difference.
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.
A sign of heat transfer is when there is a change in temperature. Heat will flow from a region of higher temperature to a region of lower temperature until thermal equilibrium is reached. Temperature difference is a key indicator of heat transfer.
No, heat transfer occurs due to a temperature difference between two substances. If both substances are at the same temperature, there is no temperature gradient to drive heat transfer, so no heat transfer will occur.

yes
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.

heat is the transfer of thermal energy because of difference in what?
The rate of heat transfer is greater in the fridge compared to the freezer because the temperature difference is typically smaller between the inside of the fridge and the outside environment than the temperature difference between the freezer and the outside. Heat transfer is directly proportional to the temperature difference, so a smaller temperature difference in the fridge leads to a higher rate of 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.
Heat transfer involves the movement of thermal energy from a region of higher temperature to a region of lower temperature. This transfer of heat between objects or substances can result in a change in temperature. The direction and rate of heat transfer is influenced by the temperature difference between the two objects.
Heat work is the transfer of thermal energy between two systems due to a temperature difference. It affects the overall energy transfer in a system by increasing the internal energy of the system, leading to changes in temperature and phase transitions.
any where but condition is there should be temperature difference
