Answer:
In an experiment the independent variable is special type of control which is control by the experimenter, and it effect the dependent variable.
Explanation:
In dependent variable:
The dependent variable is the variable which is controlled by the experimenter to check its effect on dependent variable.
Dependent variable:
It is variable which being measured in an experiment and which is directly depend upon independent variable.
The both variables are relate in term of cause and effect. The independent variable is changed by experimenter and its effect produce in dependent variable is then measure.
For example:
To measure how sleep of student effect the test score. The time for a sleep is given by experimenter it is independent variable which may exceed or decreased. It depend upon experimenter choice but the effect on score is dependent variable which depend upon the time of sleep.
The aspects not accounted for in the ideal gas law are the force of attraction of the gas molecules on each other and the volume of the gas molecules.
- In the ideal gas law, it it assumed that the molecules of the gas are so far away from each other and thus they do not exert a significant force of attraction on each other.
- Also, the volume of each molecule of gas is <u>neglected</u> and assumed negligible and thus does not account for the <u>overall volume of the gas.</u>
<u />
So, the aspects not accounted for in the ideal gas law are the force of attraction of the gas molecules on each other and the volume of the gas molecules.

Answer:
2.27%
Explanation:
The observed value of the boiling point = 71.8°C
The actual value of the boiling point = 70.2°C
We need to find the percentage error of the student's measurement. The percentage error in any value is given by :
So, the required percentage error is 2.27%.
Answer:
c. I, II and III
Explanation:
The cell is as follows
Cr / Cr⁺²(1M) // H⁺ ( 1 M ) / H₂
Standard reduction potential of hydrogen cell is zero . Standard reduction potential is negative E for Cr⁺² / Cr(1M) half cell
Cell potential = Ecathode - Eanode
= 0 - ( - E)
= E
E is cell potential and also standard cell potential or emf of the cell .
Standard reduction potential that is for Cr3+/Cr. is - E .
Hence statement I , II , III are right . IV th statement is wrong because of sign
Option c is correct.
Answer:
Jupiter
Explanation:
Its larger mass creates a stronger gravitational pull
