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.

Many of water's emergent properties, such as its cohesion, its high specific heat, and its high heat of vaporization, result fro
Bingel [31]

Answer:

Option 5.

Explanation:

Many of the properties of water like high specific heat, cohesion, high vaporization heat, etc can be contributed to the polar nature of water molecule.

Water being a polar molecule as it contains positively charged hydrogen and an electro-negative oxygen which results in uneven or non uniformity in sharing of electrons which leads to dipole formation and hence polarization of the molecule due to which it attracts its neighboring molecules.

This polar nature imparts the properties like cohesion, surface tension , adhesion, etc due to the presence of hydrogen bonds in water molecule.

An electron in a mercury atom drops
aksik [14]

Since the electron dropped from an energy level i to the ground state by emitting a single photon, this photon has an energy of 1.41 × 10⁻¹⁸ Joules.

<h3>How to calculate the photon energy?</h3>

In order to determine the photon energy of an electron, you should apply Planck-Einstein's equation.

Mathematically, the Planck-Einstein equation can be calculated by using this formula:

E = hf

<u>Where:</u>

  • h is Planck constant.
  • f is photon frequency.

In this scenario, this photon has an energy of 1.41 × 10⁻¹⁸ Joules because the electron dropped from an energy level i to the ground state by emitting a single photon.

Be-36 what hull type is best for use on ponds, small lakes and calm rivers?
LenaWriter [7]
The hull type that is best for use on ponds, small lakes and calm rivers is Flat Bottom Hull. 
A flat bottomed boat is a boat with a flat bottomed, two-chined hull, which allows it to be used in shallow bodies of water, such as rivers, because it is less likely to ground. The flat hull also makes the boat more stable in calm water.
