Length: The most common units that we use to measure length in the metric system are the millimeter, centimeter, meter, and kilometer. The millimeter is the smallest commonly used unit in the metric system
Mass: Kilogram.
Liquid volume: The basis of fluid volume units for the metric system is the liter. A liter is about the same as one quart.
- The independent variable in an experiment is the variable whose value the scientist systematically changes in order to see what effect the changes have.
- A dependent variable is what the experimenter observes to find the effect of systematically varying the independent variable.
- Experimental constants are values that do not change either during or between experiments.
- A controlled variable is a variable that could change, but that the experimenter intentionally keeps constant in order to more clearly isolate the relationship between the independent variable and the dependent variable.

Explanation:
As it is known that 
molecule is a non-linear molecule. Therefore, its isochoric heat capacity will be as follows.
= 
= 18 R
Also, 
where, 
= molar heat capacity
M = molecular mass
= specific heat
Hence, calculate the value of as follows.
This means that value of isochoric specific heat is 
.
Yes, we have to assume ideal gas behavior because for ideal gas:
dU = 
Whereas for real gases "
" has to be added here.
Answer: Compound
Explanation:
Copper(II) oxide or cupric oxide is the inorganic compound with the formula CuO. A black solid, it is one of the two stable oxides of copper, the other being Cu₂O or copper(I) oxide. As a mineral, it is known as tenorite.
Answer is b..............…
A very electronegative atoms has a strong ability of attracting electrons towards itself. As a result, it would gain electrons more than it usually has. Therefore, it would form an anion, or a negatively charge ion. These ions readily accepts electrons from the valence of other elements.
