Ответ:
Weight of the soil (500g)
Explanation:
According to this question, some students are conducting an experiment in order to find out which of the different soils used absorb heat the fastest. For the first test, they put 500 grams of SAND in a beaker and put a thermometer in the sand.
In an experiment, the variables that must be kept constant for all the groups is called the CONSTANT OR CONTROLLED VARIABLE. This is done in order not to influence the outcome of the experiment. In this case, the weight (500g) of the soil should be kept the same for all other tests.
This means that for the remaining soil being tested, 500g of each type of soil should be used.
