Iron atoms are heavier than gold atoms
Explanation:
Chart:
Materials Specific heat
Gold 0.129
Iron 0.45
The specific heat of a substance is the amount of heat required to raise the temperature of 1g of the substance by 1K.
We can see that the more the mass of a substance, the higher the specific heat needed to raise the temperature.
Specific heat is directly proportional to the mass of substance.
It also dependent on the amount of heat supplied and the nature of the substance.
- The mass of a body is the amount of substance it contains.
- A heavier substance has more number of atoms in it.
- Since iron has a higher specific it, the atoms must be heavier or more than that of gold.

Answer: The thermal energy transfer is When a fluid, such as air or a liquid, is heated and then travels away from the source, it carries the thermal energy along.
Explanation: heat transfer is called convection. hopefully this was helpful.
Answer:
weight on earth is mg
which is 5*9.8
49 Newton
weight on moon is 1/6 th of weight on earth
1/6*49
8.166 Newton..
By the admiring tone that the writer has for the gift that she/he received, it is clear that there's a lot of imagery. The writer also described the rose as "perfect", "scented dew still wet", and "pure", which further supports the idea that he/she is describing the gift.
Answer:
a. metallic bond
b. the valence electrons from the s and p orbitals of the interacting metal atoms delocalize. That is to say, instead of orbiting their respective metal atoms, they form a “cloud” of electrons that surrounds the positively charged atomic nuclei of the interacting metal ions.
c. due to the presence of free electrons in its outer energy levels
