The temperature of an object is directly related to A. the volume of the object. B. the motion of its particles. C. the potentia
2 answers:
Answer: Option (B) is the correct answer.
Explanation:
In a solid object, molecules are closely packed together due to strong intermolecular forces between them. So, when heat is provided to the object then forces between the atoms decreases and as a result, atoms start to move from their initial place.
Hence, atoms gain kinetic energy due to increase in their motion.
For example, when ice is heated it changes into liquid state of water.
Also, K.E =
where k = Boltzmann constant
T = temperature
Hence, kinetic energy is directly proportional to temperature.
Thus, we can conclude that the temperature of an object is directly related to the motion of its particles.

Answer: The balanced equation for the complete oxidation reaction that occurs when methane (CH4) burns in air is .
Explanation:
When a substance tends to gain oxygen atom in a chemical reaction and loses hydrogen atom then it is called oxidation reaction.
For example, chemical equation for oxidation of methane is as follows.
Number of atoms present on reactant side are as follows.
- C = 1
- H = 4
- O = 2
Number of atoms present on product side are as follows.
- C = 1
- H = 2
- O = 3
To balance this equation, multiply by 2 on reactant side. Also, multiply
by 2 on product side. Hence, the equation can be rewritten as follows.
Now, the number of atoms present on reactant side are as follows.
- C = 1
- H = 4
- O = 4
Number of atoms present on product side are as follows.
- C = 1
- H = 4
- O = 4
Since, the atoms present on both reactant and product side are equal. Therefore, this equation is now balanced.
Thus, we can conclude that balanced equation for the complete oxidation reaction that occurs when methane (CH4) burns in air is .
