Answer: The average kinetic energy of water at is .
Explanation:
Given: Temperature =
Kinetic energy is the energy acquired by the molecules of a substance due to its motion.
Formula to calculate average kinetic energy is as follows.
where,
T = temperature
k = Boltzmann constant =
Substitute the value into above formula as follows.
Thus, we can conclude that the average kinetic energy of water at is .
Answer:
144 g of phosphorus contain 4.65 moles.
Explanation:
Given data:
Mass of phosphorus (P) = 144 g
Number of moles = ?
Solution:
Formula:
Number of moles = mass/ molar mass
Molar mass of phosphorus is 31 g/mol
Now we will put the values in formula.
Number of moles = 144 g/ 31 g/mol
Number of moles = 4.65 mol
Thus, 144 g of phosphorus contain 4.65 moles.
The interaction between the substances and stomata is a chemical reaction, light energy strikes at the chlorophyll molecules, whose electrons gets excited to a state of higher energy, and they come back to their state of lower energy by emission of energy, which is accepted by a chain of acceptors, and energy is generated.
