The lab procedure involves several factors, listed below. Some were variable and some were constant. Label each factor below V for variable or C for constant. square mass of the water in the calorimeter square mass of the metal square change in temperature of the water square change in temperature of the metal square volume of water in calorimeter square calorimeter pressure square specific heat of water

In a lab procedure, certain factors are kept constant to ensure that the experiment is fair and that the results are reliable. These constant factors do not change throughout the experiment. On the other hand, variable factors are those that can change or be changed during the experiment. In this case, the mass of the water in the calorimeter, the mass of the metal, the change in temperature of the water, the change in temperature of the metal, the volume of water in the calorimeter, the calorimeter pressure, and the specific heat of water are all variable factors because they can change during the experiment. The only constant factor is the calorimeter pressure, as it is not mentioned that it changes during the experiment.
