A student adds ice to several samples of water. The results are shown in the table. Which conclusion can be drawn from the results?
The independent variable in the investigation is the amount of ice cubes added.
The graph of the relationship between temperature and kinetic energy in one phase of matter would be a diagonal line. As temperature increases, the kinetic energy of the particles in the matter also increases.
Sample Initial Final Amount of Ice
Temperature (*C) Temperature (*C) Added (grams)
1 20.2 16.0 60
2 48.1 44.2 59.9
3 6.1 1.0 71.1
4 14.6 14.6 122.6
A student adds ice to several samples of water. The results are shown in the table. Which conclusion can be drawn from the results?
A student adds different amounts of ice to four samples of water and records the change in temperature after 30 minutes. What is the independent variable in the investigation?
final temperature
amount of time
initial temperature
ice cubes added
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?
