For studying the absorption of water by different types of wood, independent variables could include the type of wood being tested (e.g., oak, pine, maple), the surface area of the wood exposed to water, and the temperature of the water used for soaking the wood. These variables can be controlled and manipulated to understand their effects on water absorption by the different types of wood.
What else can I help you with?
What is a dependnt variable?
a dependent variable is the thing in your experiment you are testing or the thing that you are influencing. for example temperature. The independent variable changes on its on for example time. If you had a question : How long does it take for the water to reach 25c; the water temp is the dependent as you are measuring it, and the time is independent because you are not affecting it.
Why do cotton balls shrink when absorbing water?
Cotton balls shrink when absorbing water because the water molecules cause the cotton fibers to swell and become more tightly packed together. As a result, the fibers contract in size, leading to the overall shrinkage of the cotton ball.
What is the dependent variable for a tornado in a bottle?
The dependent variable for a tornado in a bottle experiment could be the speed of the tornado rotation or the duration of the tornado formation. This variable would be affected by the independent variables being manipulated in the experiment, such as the amount of water or the speed of the vortex created.
When water at 212 degrees Fahrenheit boils it is only absorbing latent heat?
Yes, at 212 degrees Fahrenheit, water has reached its boiling point and will undergo a phase change from liquid to gas. During this process, the water is absorbing latent heat energy to break the intermolecular bonds holding the water molecules together, rather than increasing in temperature.
What materials stop radiation and how do they provide protection?
Materials such as lead, concrete, and water are effective at stopping radiation. These materials provide protection by absorbing and blocking the harmful radiation particles, preventing them from penetrating through and reaching living organisms. Lead, for example, is dense and has a high atomic number, which makes it effective at absorbing and stopping radiation. Concrete and water also act as barriers, slowing down and absorbing radiation particles to reduce their harmful effects.
What is the independent and dependent variables when you water plants with milk or water?
The independent variables are the milk and water, while the dependent variables are the plants, because they don't change.
What are the controlled variables and changed variables when soybeans absorb water?
The controlled variable is the type of soybean, and the changed variable is the type of water that the soybean is absorbing.
Things that may change during a experiment are called?
'Variables' are any factors that can be controlled, changed or measured. There are two types: the independent variable and the dependent variable. The independent variable is the condition that you change and the dependent variable is what you are observing. So if you are trying to measure the effect of water on plant growth the water would be the independent variable and the plant growth would be the dependent variable.
What are the independent variables in coffee dissolving in hot water?
These are: temperature, coffee granulation, type of coffee.
1 paragraph about investigating skittles in water?
The independent variable was the amount of skittles or M&Ms. One of our controlled variables was the amount of water.
What do dependent and independent variables represent in science?
In science, independent variables are variables that you control the change of, to see how somethings changes as a result of changing these variables. Dependent variables are variables that change because the independent variables are changed, but you don't change directly. A good example of this would be an experiment where you're measing how cold a glass of water gets after putting in different amounts of ice in it and wating 5 minutes. The independant variable would be the amount of ice you put into each glass, because that's what you're directly changing. The dependent variable is how cold each glass gets, because that's the result you're trying to see by changing the independent variable - it changes because something else changes. Additionally, when graphing, independent variables are put on the x-axis (horizontal line), and dependent variables are put on the y-axis (vertical line).
What are the controls and variables for Seperating salt from water?
I dont know about the control but the independent variable is the amount of salt water and the dependent variable is the amount of water and salt rendered.
Is water a variable?
It can be, it depends on your experiment. Independent variables are the variables in an experiment that will not change. If you want to do an experiment that tests how something reacts with water, then starting with a clean controlled water sample for each test would be necessary and an independent variable. Conversely, if you were testing the cleanliness of multiple water sources, then the ideology of clean water would be your dependent variable, which would change upon each testing. WIth your given information I cannot say whether or not you would want water to be either a dependent or an independent variable for your experiment.
The effect of Gatorade VS water on seventh graders pulse rates while exercising what are the dependent and independent variables of this exeperiment?
Independent . . . what substance the 7th grader drinks Depoendent . . . his pulse rate
Are the water absorbing roots different from food absorbing roots?
tagina
What is porous water absorbing material?
Porous water-absorbing materials are substances that have small pores or holes in their structure, allowing them to soak up and retain water. Examples include sponges, foam, and certain types of fabrics like cotton or wool. These materials are commonly used in products such as diapers, sponges, and water filters.
What are the 3 scientific variables?
The three scientific variables are independent variables, dependent variables, and controlled variables. The independent variable is the variable that is manipulated or changed by the researcher. The dependent variable is the variable that is measured or observed in response to the changes in the independent variable. Controlled variables are the factors that are kept constant to ensure that they do not influence the relationship between the independent and dependent variables.
