What are the independent and dependent variables in this experiment?

What are the independent and dependent variables in this experiment?

The variables in a study of a cause-and-effect relationship are called the independent and dependent variables. The independent variable is the cause. Its value is independent of other variables in your study. The dependent variable is the effect.

What is the difference between independent and controlled variables?

Independent variable – the variable that is altered during a scientific experiment. Controlled variable – a variable that is kept the same during a scientific experiment. Any change in a controlled variable would invalidate the results.

What is the difference between dependent and independent on taxes?

Dependents are individuals that receive care from others, such as the children whose expenses are covered by parents. Individuals that qualify as dependents face different tax rules than independent taxpayers.

Is pressure a dependent or independent variable?

If you manipulated the volume and measured the pressure as a result, the volume would be the independent variable and the pressure would be the dependent variable because the pressure was dependent on the volume.

What is the dependent variable in Charles Law?

Charles’s law states that for a gas at constant pressure, volume in directly proportional to temperature. The volume of a mass of gas is dependent on the temperature and pressure. Therefore, these conditions must be given along with the volume of a gas.

What is the dependent variable in Boyle’s law experiment?

BOYLE’S LAW. – he wanted to investigate the relationship between pressure and volume. ▪ independent variable = pressure. ▪ dependent variable = volume. ▪ controlled variables = temperature and number of moles (no gas enters.

Is pressure dependent on volume?

The state of a gas is defined by various properties which we can observe with our senses, including the gas pressure (p), temperature (T), mass (number of moles – m), and volume (V) which contains the gas. The value of pressure and temperature does not depend on the amount of gas used in the measurement.

What are the constant variables in Boyle’s law?

Robert Boyle’s observations are summed up in Boyle’s law, which states that for a given mass of gas at constant temperature, the volume of a gas varies inversely with pressure. Because of the inverse relationship, the product of the two quantities, pressure and volume, is constant.

What volume does gas have at STP give the equality?

22.4 L

What are the independent and dependent variables in this experiment?

Independent vs Dependent Variables An independent variable is the variable that is changed or controlled in a scientific experiment to test the effects on the dependent variable. A dependent variable is the variable being tested and measured in a scientific experiment.

What is the independent variable of this experiment answer?

The independent variable (IV) is the characteristic of a psychology experiment that is manipulated or changed by researchers, not by other variables in the experiment. For example, in an experiment looking at the effects of studying on test scores, studying would be the independent variable.

What was the independent variable in Joe’s experiment?

In Joe’s experiment, what is the independent variable? The independent variable is the detergent.

What is a characteristic of an independent variable?

What is a characteristic of an independent variable? It varies with a change in the dependent variable. C. It is manipulated by the researcher.

What are the most important characteristic of an independent variable?

Independent variables are variables for which an association with the dependent variables is sought. These variables can include subject characteristics and interventions, but sometimes outcomes that may be predictive or causal of other subsequent outcomes.

What are the types of independent variables?

Independent Variables: Other Names and Uses.

• A controlled variable.
• An explanatory variable.
• An exposure variable (in reliability theory).
• A feature (in machine learning and pattern recognition).
• An input variable.
• A manipulated variable.
• A predictor variable.
• A regressor (in regression analysis).

Why is time always an independent variable?

In this question, time is the independent variable and displacement is the dependent variable. The experimenter can select sampling times, but cannot necessarily predict the displacement that will be measured at each point. This defines time as the independent variable.

Does heating water allow more sugar to be dissolve independent variable?

Sugar dissolves faster in hot water than it does in cold water because hot water has more energy than cold water. When water is heated, the molecules gain energy and, thus, move faster. As they move faster, they come into contact with the sugar more often, causing it to dissolve faster.

Is dissolving wet or dry?

What is the quickest way to dissolve milk in water?

Answer. Answer: the quickest way they dissolve milk in water is to use hot water because if If u use cold water it will take time until it’s fully dissolve but when u use hot water it would be more easier to dissolve and more faster.

What is the dependent variable when dissolving salt and sugar?

Over 1000 FREE Science Fair Project Ideas! 1. For this experiment, the independent variable is the temperature of the solvent (water) and the type of substance used – sugar, salt and sodium bicarbonate. The dependent variable is the amount of substance dissolved in the water.

What is the control variable example?

Examples of Controlled Variables Temperature is a common type of controlled variable. If a temperature is held constant during an experiment, it is controlled. Other examples of controlled variables could be an amount of light, using the same type of glassware, constant humidity, or duration of an experiment.

Is Salt a dependent variable?

Independent variables include type of salt (i.e. rock salt, table salt) and amount of salt (i.e. no salt, 1/2 tsp., 1 tsp., 1 tbls.). Time (in seconds) for ice to melt was used as the dependent variable.
