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:
Tin and Copper
Explanation:
The two atoms that could potentially form alloys are the tin and copper atoms.
Alloys are mixtures formed between two or more metals.
The goal of forming alloys is to take properties of one metal and add to that of another metal so as to enhance both materials.
Alloys are only formed between metals.
The only metal pair given from the choices is that of tin and copper.
Therefore, the two atoms that could potentially form alloys is tin and copper.
Answer:
2.33×10¯¹⁶ g of forsterite
Explanation:
From Avogadro's hypothesis, we understood that 1 mole of any substance contains 6.02×10²³ atoms. This equally means that 1 mole of forsterite (Mg2SiO4) contains 6.02×10²³ atoms.
1 mole of forsterite (Mg2SiO4) = (24×2) + 28 + (16×4)
= 48 + 28 + 64
= 140 g
Finally, we shall determine the mass of forsterite that contains a million oxygen atoms.
140 g of forsterite (Mg2SiO4) contains 6.02×10²³ atoms.
Therefore, Xg of forsterite (Mg2SiO4) will contain 1×10⁶ atoms of oxygen i.e
Xg of forsterite (Mg2SiO4) =
(140 × 1×10⁶) /6.02×10²³
= 2.33×10¯¹⁶ g
Therefore, 2.33×10¯¹⁶ g of forsterite contains a million oxygen atoms..
