Answer:

Dependent variable: A dependent variable can be described as the one which is dependent on the independent variable. It can be described as a variable which is under observation or the variable on which experiments is being made.

An independent variable can be described as a variable which is not dependent on any factor. Changes in the independent variable bring changes in the dependent variable.

The independent variable is the Sun and the dependent variable is the specific heat capacity. As air has lower heat capacity, hence it will cool faster than water.

Which element is most likely to gain electrons in a chemical reaction?
tatyana61 [14]
Option 2, Br. I'll go over why all other three options are incorrect.

Option 1 - Krypton is a Noble gas, and so it doesn't need to accept electrons since it has an octet.

Option 3 and 4 - Both Calcium and Barium are alkaline earth metals, and give away electrons, since they only have 2.
