The independent variable in this investigation is the ice cubes added. This is the variable that the student is deliberately changing to observe its effect on the temperature.

A student conducts an investigation to show the relationship between temperature and kinetic energy in one phase of matter. What would the graph of this relationship look like?(1 point)

a diagonal line

The graph of the relationship between temperature and kinetic energy in one phase of matter would look like a diagonal line. As the temperature increases, the kinetic energy of the particles generally increases, resulting in a positive linear relationship.
