Kinetic energy is _____.
2 answers:
Explanation:
Kinetic energy is defined as the energy obtained by an object due to its motion.
This means that any object which is moving will have kinetic energy because it is in motion.
Mathematically, K.E =
where, m = mass of object
v = volume of object
Whereas if an object is not moving and if it is only lying in a certain position then it will have only potential energy.
Thus, we can conclude kinetic energy is the energy obtained by an object due to its motion.

Answer:
Explanation:
Pair 2.50g of O₂ and 2.50g of N₂
The atoms sample with the largest number of moles since the masses are the same would be the one with lowest molar mass according the the equation below:
Number of moles =
Atomic mass of O = 16g and N = 14g
Molar mass of O₂ = 16 x 2 = 32gmol⁻¹
Molar mass of N₂ = 14 x 2 = 28gmol⁻¹
Number of moles of O₂ = = 0.078mole
Number of moles of N₂ = = 0.089mole
We see that N₂ has the largest number of moles
