<em>Kinetic molecular Theory points:</em>
1. Gases molecules are always in random motion.
2. Gases molecule collide with each other and with the walls of container.
3. Gases molecules total volume is negligible as compare to container.
4. There is no attractive forces between the gases particles
5. K.E is directly proportional to absolute temperature.
<em>Why liquid are denser than gases according to K.M.T:</em>
1. As gases are in random motion, so they have weak forces/ no attractive forces (Acc. to KMT) due to this they are apart as compare to liquid which have stronger forces are closer to each other. So volume of gases will be greater. d= m/v
2. K. E of gases are greater than liquid due to this gases move randomly, apart from each another. Due to this their volume will be greater. d= m/v
3. Gases molecules total volume is negligible as compare to container which show that gases molecules have large spaces between them which causes lower in density.
Answer:
E. temperature of the water
Explanation:
The independent variable is the variable that changes, and it's also the variable that the dependent variable's results depend on. So depending on the temperature of the water, results in the ice cubes height. So the independent variable is the temperature of the water.
Answer:
Monomer liquid and polymer powder nail enhancement are lucrative service
The compound originally contained KNO₃ solution.
Explanation:
When a mixture which contains either Pb(NO₃)₂ or KNO₃ is added with NaCl solution, no reaction takes place. This confirms the presence of KNO₃ in the solution.
The reason behind the above activity can be attributed to the lower placement of Na (sodium) in reactivity charge than potassium (K). Hence, it cannot displace Potassium (K) from the aqueous KNO₃ solution. Whereas the NaCl reacts with Pb(NO₃)₂ to produce white insoluble precipitate of PbCl₂. This confirms the presence of KNO₃ in solution.
