22 lut 2022 · Experiments are designed to provide an opportunity to make observation that will help test a hypothesis. Experiments are best understood in term of three types of variables: independent variables, dependent variables, and controlled variables.
In an experiment, a Chemist causes a change and records the effect of that change. The quantities that can be changed are called variables. There are three types of variables: (a) independent variables. (b) dependent variables (1) (c) constant variables (1) Independent variable is the quantity that the Chemist causes to change.
30 sie 2022 · The factors that can change value during an experiment or between experiments, such as water temperature, are called variables, while those that stay the same, such as acceleration due to gravity at a certain location, are called constants.
