Answer:
Nuclear fusion plays an important role in making elements that are heavier than helium.
Explanation:
Nucleosynthesis is the process by which new atomic nuclei are created from pre-existing nucleons (protons and neutrons) and nuclei. According to current theories, the first nuclei were formed a few minutes after the Big Bang, through nuclear reactions in a process called Big Bang nucleosynthesis.
In order to synthesize a new element, there must be a change in the number of protons. We should remember that elements are known by the number of their protons as it represents their atomic number.
Elements heavier than helium are formed by nuclear nucleosynthesis in which nuclear fusion plays a very crucial role as typified by the equations shown in the question.
When we wish to convert a gas to liquid we have to either
a) decrease temperature
b) increase pressure
In case of fire extinguisher the CO2 is found to be in liquid state, this is as the CO2 is pressurized at high pressure which keeps CO2 in liquid state
the ideal pressure and temperature conditions when CO2 gas can be converted to CO2 gas
Pressure = 5 - 73 atm
Temperature = -57 to 31 degree Celsius
Answer:
what's the qstn first ?????
<span>There are three process by which the heats are transferred.They are conduction,convection & radiation. The concept of thermos flax designed to avoid all these process,that is why we are able to keep at required temp without loss are gain of temp. The convection is a method by which the heat is transfer through third media.Please look in to my site for earth section.The heat at mandrill is transferred to lithosphere and to crest by the medium called magma. This is carrying the heat from inner layer to outer core of the earth.How the egg immersed in hot water is boiled is the same process.</span><span />
Answer:
if u have to round it to the nearest ones plat 3.2 or 3.1 and if u have to round to the tenths place 3.16
