You’ve been waiting for the bus and your hands become cold. When you get onto the bus and sit down, you put your hands under you
snow_tiger [21]

Explanation:

The <u>First Law of Thermodynamics</u> states that energy cannot be created or destroyed in an isolated system. In other words, energy can be converted from one form into another, but it cannot be created nor destroyed.

<u>Conduction</u> is the transfer of energy from one molecule to another by direct contact. This transfer occurs when molecules hit against each other, which can take place in solids, liquids, and gases.

When you put your cold hands under your legs to warm your hands up, the heat energy from your legs is being transferred to your hands through conduction. However, since energy cannot be created, there is no extra heat energy that can instantaneously replace the heat created by your legs.

Give the nuclear symbol for the isotope of gallium, ga, that contains 40 neutrons per atom. Replace the question marks with the
Cerrena [4.2K]

The nuclear symbol of an element have three parts namely:  

  1. the symbol of an element
  2. mass number of the element
  3. atomic number of the element

The general representation is as:

_{Z}^{A}X

where X is the chemical symbol of the element, A is mass number of the element that is total number of neutrons and protons in the nucleus of an atom, and Z is atomic number of the element that is number of protons in the atom.

Element = Gallium, Ga    (given)

Number of neutrons = 40 (given)

Let the nuclear symbol be _{?}^{?}Ga. So, we need to determine the values of "?" in the symbol.

Atomic number of Gallium, Ga = 31

Since, atomic number = Number of protons.

So, number of protons of Gallium, Ga = 31

Mass number = number of protons + number of neutrons

Substituting the values:

Mass number = 31+40 = 71

So, the nuclear symbol is _{31}^{71}Ga.
