Identify the total distance, total time, and average speed shown for the object on the graph.

Which statement describes the appearance of a temperature-vs.-time graph? a horizontal line shows that the temperature increases at a constant rate over time. a vertical line shows that the temperature decreases at a constant rate over time. horizontal lines where the temperature is constant during phase changes connect upward-sloping lines where the temperature increases. horizontal lines where the temperature increases are connected by upward-sloping lines where the temperature is constant for each phase.

Frictional forces acting on an object are often converted into energy, which causes the temperature of the object to rise slightly.

How does concentration affect reaction rate
