Reaction A temperature went down, Reaction B went up
Reaction A lost 30 degrees, and REaction B gained 16 degrees
Temperature rose in reaction A, but fell in reaction B.
Both reactions gained temperature.

Neither, they would be the same
How would you determine the density of an irregular object?
Length x width x height
use a ruler and a triple beam balance
use a graduated cylinder
Use a graduated cylinder and a triple beam balance
How does the density of liquid water compare with the density of ice?
Ice has a greater density
liquid water has a greater density
Water is lower in density than ice
