Which graph shows the relationship between temperature, X, and kinetic energy, Y?
Answer
A
Image with description A graph with the x axis labeled X and the y axis labeled Y. There is a horizontal line.
B
Image with description An illustration of a triangle with the base labeled X with the height labeled Y.
C
Image with description A graph with the x axis labeled X and the y axis labeled Y. There is a diagonal line from the origin.
D
Image with description A graph with the x axis labeled X and the y axis labeled Y. There is a vertical line.
Explanation
As temperature increases, the average kinetic energy of particles increases in direct proportion. A direct relationship is shown by a diagonal line rising from the origin, so the correct choice is the graph with that line.
