the particles that make up a rock are constantly moving. however, a rock does not visibly vibrate. why is this?
Answers
An example similar to this one would be diamond. It is made up of carbon bonds. But once you take a (real) diamond out of the ground, it very slowly, not visible to the human eye, yet surely is turning back into graphite. (another substance made by carbon bonds)
i hope this helped.

Answer:
300 J.
Explanation:
- The first law of thermodynamics is the law that demonstrates the conservation of energy.
- It states that the total energy of an isolated system can not be created or destroyed, but it may be transformed into another form.
- The energy released to the room is 300 J.
- So, according to the law of conversation of energy; the amount of heat removed from food inside of the refrigerator is 300 J.

Answer: Synthesis reaction
Explanation:
Corrosion is the process of slow eating away of metal due to attack of atmospheric gases on the surface of metal resulting into formation of compounds such as oxides, sulfides , carbonates etc is called as corrosion.
Corrosion of iron is called as rusting. Rust is hydrated ferric oxide .
Synthesis reaction is a chemical reaction in which two reactants are combining to form one product.

Answers
Answer:
Option A. Dense water floats.
Explanation:
Ocean circulation act as conveyor belt which transport warm water from the tropics towards poles from where cold water sinks to the deep ocean. It is also known as the thermohaline circulation because it is driven by salinity and temperature.
However, change in climate causing these ocean's thermohaline current to slow down because influx of cold and melting fresh water from the polar region is disrupting these circulation as influx of fresh water making the water less saline and less dense and hence it become harder to sink to deep ocean.
Answer:
C. Increase in temperature - Ice melts and freshens water - Freshwater floats over denser salty water

Answer is: 3) francium.
The atomic radius of a chemical element is a measure of the size of its atom.
The atomic radius varies with increasing atomic number, but usually increases because of increasing of number of electrons.
Potassium (K), rubidium (Rb), ceasium (Cs) and francium (Fr) are in group 1 (the alkali metals) of the periodic tabl.
The atomic radius increases down the group of Periodic table and francium is on the bottom of the group 1 with highest atomic number.
Final answer:
The atom with the largest atomic radius among potassium, rubidium, cesium, and francium is francium, due to it being furthest down the group of alkali metals.
Explanation:
The atomic radius increases as we move down a group on the periodic table. This is because the number of energy levels increases, which causes the electron cloud to expand. Hence, in this case, the largest atomic radius would belong to francium, as it is the furthest down the group of alkali metals (which includes potassium, rubidium, and cesium).
