Speed
A change over time is often referred to as a gradual change.
Speed is the rate of motion usually expressed as distance traveled per unit of time.Velocity is the rate of change of position. Both speed and direction are required. Acceleration is the rate of change in velocity. In common speech, acceleration is only for an increase in speed; a decrease in speed is deceleration. In physics, any increase or decrease in speed or change of direction is referred to as acceleration.

change in speed is acceleration. change in speed is the slope of the speed versus time graph, or the derivative of such.

To different individuals, it may or may not have any significance. The quantity is typically referred to as "speed", and you're free to decide for yourself whether it has any relevance in your life.
Motion occurs when there is speed. A change of speed is not required.
due to acceleration the speed and velocity will change automatically
Change in speed (more precisely change in velocity) is called acceleration.
Motion occurs when there is speed. A change of speed is not required.
Temperature can change the speed of some reactions.
