Two blocks of platinum have a temperature of 200 Celsius. Both the blocks have the same amount of thermal energy because both are metals which conducts heat energy throughout their bodies.
<h3>What is conduction?</h3>
Conduction is the process by which heat energy is transmitted between neighboring atoms or molecules. We know that metals are the good conductors of heat and electricity so if one part absorb heat, it will spread to the whole body so we can conclude that the thermal energy will remain the same amount throughout the whole body.

Answer: Option (a) is the correct answer.
Explanation:
The given data is as follows.
wavelength of red photon (
) = 700 nm
wavelength of infrared photon (
) = 1750 nm
Therefore, calculate the wavelength of absorbed photon as follows.
= 
= 
or, 
= 
= 500 nm
Therefore, we can conclude that the wavelength of the absorbed photon is 500 nm.
<u>We are given:</u>
Mass of NaCl in the given solution = 22.3 grams
Volume of the given solution = 2 L
<u></u>
<u>Number of Moles of NaCl:</u>
We know that the number of moles = Given mass / Molar mass
Number of moles = 22.3 / 58.44 = 0.382 moles
<u></u>
<u>Molarity of NaCl in the Given solution:</u>
We know that Molarity of a solution = Moles of Solute / Volume of Solution(in L)
Molarity = 0.382 / 2
Molarity = 0.191 M

That statement is true.
Reason: If you are familiar with the cell theory, the cell theory states 3 things:
- All living things are made up of cells
- Cells are the basic unit of life
- Cell comes from other cells
Any living things are made up of cells- which is why cells are considered the building blocks of life on Earth.
Hope this helps!! :)
