If something is hotter and smaller does it give off a greater luminosity?
an increase in temperature or radius causes an increase in luminosity, assuming the other variable doesn't change. luminosity is the total energy output, rather than a measure of energy output against size.
What can make a planet's surface change?
THe temperature
How and why is clouds forming in the sky a physical change?
because condensation is simply just a change of the water temperature in the air. a temperature change is a physical change. clouds form when the water vapor condenses, so therefore, cloud formation is a physical change.
Why do stars seem to change color?
Because their temperature is changing.
What do you notice happens with temperature of the sun as you move outward from the sun?
The sun doesn't care where we are. Its temperature doesn't change as we move about.
In an experiment where you change only the temperature temperature is the?
manipulated variable
What is the temperature called when you purposely change the temperature to test a hypothesis?
A variable
What kind of variable is part of the experiment that is affected by the independent variable?
Dependent Variable the independent variable is the one you change to get the dependent variable. The control group is the thing that you leave the same throughout your experiment. Hint: You don't want too many independent variables, it will mess up the experiment.
If temperature is allowed to change in an experiment the temperature would be a?
The answer is variable.
In a scientific experiment the is the thing the experimenter deliberately change while observing.?
Independent variable. Apex
What is a dependnent variable?
A dependent variable depends on the independent variable. If you are doing an experiment about how temperature affects the heat of water then the independent variable would be the temperature, as that is what you are going to change, and the dependent variable the water as the temperature of the water depends on the temperature surrounding it.
What is the dependent variable in a temperature experiment?
The Temperature is the Independent Variable (50 degrees, 100 Degrees etc.) Whatever happens as a result of the temperature change is the dependent variable.
In a graph showing temperature change of material over timetemperature change is the?
dependent variable
What is the temperature called when in an experiment you only change the temperature?
dependent variable
In a graph showing temperature change of a material over time temperature change is the .?
dependent variable
What is responding valuable?
Do you mean "responding variable"? In a scientific investigation, you try to change only one thing to see what happens. The thing you change is the manipulated variable (also called the independent variable). The result of this change is the responding variable (also called the dependent variable). For example, what if you measure the temperature of a beaker of water, then put it in the refrigerator for 24 hours, then measure again. The change in the temperature from the room to the fridge is the manipulated variable (you controlled it). Any change in the water temperature is the responding variable. It responded to the change you made.
Is the cost of fuel for vehicles a variable cost?
Variable cost: The cost change with the change in activity is called variable cost. So as much fuel used cost increased accordingly so it is variable cost.
