Which solution is the best conductor of electric
nadezda [96]

(C) 0.1 mole of NaCl dissolved in 1,000. mL of water

<u>Explanation:</u>

The conductivity of 0.1 mole of NaCl dissolved in 1000 mL of water will be greatest as the number of ions in 0.1 mole of NaCl will be more than 0.001, 0.05 and 0.005 moles of NaCl. Greater the number of ions in the solution, greater will be the conductivity. Specific Conductivity decreases with a decrease in concentration. Since the number of ions per unit volume that carry current in a solution decrease on dilution. Hence, concentration and conductivity are directly proportional to each other.

In an experiment to determine if the height of a cake is determined by the temperature at which is cooked, measuring the height
Bezzdna [24]

Answer:

  • <u>Dependent variable</u>

Explanation:

In a controlled <em>experiment </em>there will be one independent variable, one dependent variable, and some controlled or constant parameters.

The target of the expermiment is to tes how the dependent variable changes with the independent variable.

So, the scientist will change (manipulate) the independent variable and measure the dependent vabiales.

Here, the temperature will be manipulated (within a range), so this is the independent variable; the height of the cake is the variable whose behavior wants to be determined, so this is the dependent variable. Controlled variables or constants may include the mixture, the size of the pan, the time of cooking, the oven, among others.

2) Will all atoms behave exactly the same when the temperature is changed? ​
Butoxors [25]

no...the atoms will not behave the same

as when temperature is increased, the atoms vibration and kinetic energy will also be increased....they come in excited state...

where as when temperature is reduced ,atoms kinetic energy slows down....
