When the pressure and number of particles of a gas are constant, which of the following is also constant? Explain answer please
2 answers:
Answer : The correct option is, the ratio of the volume and temperature in kelvins
Explanation :
According to the Charles' Law, the volume of gas is directly proportional to the temperature of the gas at constant pressure and number of moles.
(At constant pressure and number of moles)
or,
where,
V = volume of gas
T = temperature of gas
k = constant
As per question, when the pressure and number of particles of a gas are constant then the ratio of the volume and temperature in kelvins.
Hence, the correct option is, the ratio of the volume and temperature in kelvins

Answer: Option (b) is the correct answer.
Explanation:
A covalent bond is defined as the bond which occurs due to sharing of electrons between the combining atoms.
Generally, a covalent bond is formed between non-metals.
For example, both nitrogen and oxygen atoms are non-metals and they combine covalently to form compound.
As nitrogen has 5 valence electrons and an oxygen atom has 6 valence electrons. So, there occurs unequal sharing of electrons between the two.
Thus, we can conclude that when a covalent bond forms then electrons in valence shells are shared between atoms.
