Energy diagram for and endothermic and exothermic reaction
Rows are periods, columns are groups
Answer:
It is a example of erosion
Explanation: because pieces of rock erode making it unstable a causes a landslide
La magnitud fundamental es aquella que se define por si misma y es independiente mientras que la magnitud derivada es aquella que se obtiene mediante expresiones a partir de las magnitudes fundamentales. :)
Here we have to get the right answers which include the given phrase.
The correct answers are as following:
High boiling and melting points: Hydrogen bond increase the amount of energy required for phase changes to occur, thereby raising the boiling and melting points.
High specific heat: Hydrogen bond increase the amount of energy required for molecules to increase the speed, thereby raising the specific heat.
High surface tension: Hydrogen bonds produce strong inter molecular attractions, which increase surface tension.
The incorrect answer:
Lower density as a solid than as a liquid: actually, density of solid is more than density of liquid as hydrogen bonds in solid produce strong inter molecular attractions among molecules, which aggregates molecules together, hence volume of associated molecules reduces. Therefore, density of solid is more than that of liquid.
