Ms. Hendren has decided that she would like to grow some tomatoes and wants to know how much light will cause the plant to grow
yan [13]

Answer:

The correct answer is -

Independent variable - the amount (time period) of light given to pots.

Dependent variable - size of tomatoes

Control variable - dark or absence of light

Control group - pot placed in the darkroom.

Explanation:

The independent variable is the variable that is changed or manipulated in particular research or study to see the effect of that variable on dependent variable. In this case, the amount of light each pot gets is the independent variable.

The dependent variable is the variable that depends on the change in the independent variable. The size of tomatoes is the dependent variable here.

The control variable is the variable that remains in standard condition or condition which can be used to compare with the effect of the independent variable. The absence of light on one of the tomato pot is the control variable.

The control group is the group of subjects did not get any treatment that experiment group receives. The pot which is placed in the dark room is control group here.

I need an hypothisis on How does temperature change affect surface tension?
Dafna1 [17]

Hypothesis: I believe an increase in temperature would lead to a decrease in surface tension.

Here's why: As the temperature increases, the molecular interaction between the liquids molecules becomes weaker because the hydrogen bond is the main factor for association between two molecules. It is a very weak bond to begin with, so when the temperature increases, it just further weakens it.
