Steady state heat trander means heriability of all heat transfer parameters in time Equality of temperature values in every point of space Uniformity of temperature dictrodion in space Equality of the values of temperature gradients in every point of space

The correct answer is: Uniformity of temperature distribution in space.<br /><br />In the context of steady-state heat transfer, it means that the temperature distribution within a system remains constant over time. This implies that there is no change in the temperature distribution as time progresses. The temperature at any given point in space remains the same, and the temperature gradients (rate of change of temperature with respect to distance) are also uniform throughout the system. This condition is typically achieved when there is no net heat transfer into or out of the system, and all heat transfer processes within the system are in equilibrium.
