Answer:
--- The hot air inside the bottle creates an expansion and when the hot water is applied a contraction occurs, thus causing the balloon to be sucked.
--- An internal pressure is produced, joining the heat begins to decrease. As a consequence, the air molecule causes the balloon to enter the bottle thanks to the effect of the external pressure.

No
Explanation:
In the left side of the reaction, there are 6O and 3C but on the right side, there are only 1C and 2O
Answer:
High density, metallic bonds
Explanation:
We may look at this question from the structural properties of the metals:
- metals in their solid states are the most dense phases of all the standard phases we know (solids, liquids and gases). This means the particles within a metal lattice are very closely packed. Both heat and electricity is conducted when particles interact and touch one another, so that either energy or electric current might travel from one particle to the other easily. High density means low distances between the atoms, so they can interact easily;
- the main reason, however, is the fact that metals form metallic bonds, also known as 'sea of electrons'. We have metal cations floating in a sea of their valence electrons. This forms a medium in which both heat and electricity can travel easily.
Answer:
Erosion occurs through deflation, and sand that was picked up is deposited against an obstruction.
Explanation:
Erosion can be defined as a geological process which involves the wearing away of earth material and transportation of these material to another location by Natural agents such as wind and water. Erosion involves removal of top soil, rocks and other earth particles by action of wind, glacier and water.
Wind causes erosion by deflation. Deflation is the actual removal of grain of rocks . Generally, it s the lowering of land surface that happens as a result of removal of surface particles(sands grains) by wind. Deflation is usually prevalent in arid areas. This sand can later be picked up and deposited to form sand dunes . Sand dunes are mounds of sand formed by wind . This sands are sheltered by an obstacle. And sand dunes are prevalent in desert and or along the beach. The sand dune grows as sand accumulate.
