The independent variable.The independent variable is an excellent answer, for sure, but you might also considera constant variable, ie a variable whose value can not be changed once the experiment has begun, but can be changed in subsequent experiments.For instance, we want to determine the rate at which an ice cube melts at various room temperatures. The latent heat of liquefaction does not change for water (ice) no matter the room temperature, but the rate at which that heat will be absorbed by the ice cube does change depending on the amount of heat available in the room (the room temperature).So the latent heat of liquefaction is a constant, while the temperature of the room is a variable (because we can change it), but for each individual experiment the room temperature remains constant throughout, so it becomes a constant variable.
Because it is chemical change
a process that does not change the chemical composition of a substance. A change in a substance with no new substances being formed
