Steady-state heat transfer does not change with time - because - that is the definition of steady-state, i.e. "steady-state" means "does not change with time".
As for why heat transfer might be steady state - that would be a consequence of the driving forces and physical conditions remaining constant with time. For example:
Heat source remains the same temperature
Heat sink remains the same temperature
Heat source remain in the same position relative to each other, both in terms of distance and orientation.
Surface areas of heat source and heat sink remain the same.
Any intervening medium remains the same composition, temperature, density, and pressure.
If convection is occurring, flow rates remain constant.
If radiative heat transfer is occurring, any intervening medium has constant transmissivity, reflectivity, and absorbtion.
If radiative heat transfer is occurring, radiating and absorbing surfaces maintain constant radiative and absorbing properties.
There are a few other factors that can influence steady-state heat transfer, but these are a good description of the most important ones.
The abstract noun form of the adjective 'steady' is steadiness as a word for the state of continuing without change; a word for a concept.
A steady drop in temperature is typically referred to as cooling or cooling down. This gradual decrease in temperature usually occurs over time and can have various causes, such as a change in weather patterns or the natural cooling process of an object or environment.
The correponding noun to the adjective steady is steadiness.
A continuous buffer is a type of data buffer that allows for continuous writing and reading of data without the need for pauses or breaks. It is commonly used in streaming applications where a steady flow of data needs to be processed in real-time. This buffer helps to smooth out fluctuations in data transfer rates and ensures a steady flow of information.
The steady state of ozone concentration in the stratosphere refers to a balance between the production and destruction of ozone molecules. In this state, the rate of ozone formation is equal to the rate of ozone depletion, resulting in a relatively constant concentration of ozone in the stratosphere over time. This equilibrium is essential for maintaining the ozone layer's protective effect on Earth's surface from harmful ultraviolet radiation.
In steady-state conduction, temperature and heat transfer remain constant with time, while in unsteady conduction, temperature and heat transfer change with time. Steady state occurs when the temperature distribution does not change over time, whereas unsteady state occurs when there is a time-dependent temperature distribution.
In transient heat transfer, the rate of heat transfer is changing with time. By definition, in steady-state heat transfer, the rate of heat transfer does NOT change with time. In the real world, heat transfer starts out as transient and then approaches steady-state with time until the difference between the actual and the ideal becomes negligible or until thermal equilibrium is approached.
it is the response of a system with respect to the input as a function of time
DC does not change its direction because it flows in one constant direction from the positive terminal to the negative terminal. The flow of direct current is unidirectional due to the nature of how it is generated by sources like batteries or solar panels. Unlike alternating current (AC), which changes direction periodically, DC maintains a steady flow in one direction.
AC rises with respect to time but DC is steady.
the term steady implies no change at a point in time, however particle speed can change from point to point. ie, water novel, steady flow with increase in velocity
No. Steady is an adjective. The adverb form would be steadily.
Non-steady state diffusion occurs when there is a change in concentration over time in a system.

The acceleration of a car traveling at a steady speed of 60 mph is zero. Acceleration refers to a change in velocity over time, so a steady speed means there is no change in velocity and therefore no acceleration.
If velocity is steady and doesn't change, then there is 0 acceleration.
The abstract noun form of the adjective 'steady' is steadiness as a word for the state of continuing without change; a word for a concept.
