Converting carbon to nitrogen by increasing the number of protons from 6 to 7 and decreasing the number of neutrons from 8 to 7 is an example of what type of decay?

Answers

Answer: The given decay process is beta decay.

Explanation:

Beta-decay is defined as the decay process in which a neutron gets converted into a proton and an electron releasing a beta-particle. The beta particle released carries a charge of -1 units and has a mass of 0 units.

$_Z^A\textrm{X}\rightarrow _(Z+1)^A\textrm{Y}+_(-1)^0\beta$

The chemical reaction for converting carbon nucleus to nitrogen nucleus, the equation follows:

$_6^(14)\textrm{C}\rightarrow _7^(14)\textrm{N}+_(-1)^0\beta$

Thus, the given decay process is beta decay.

this is beta decay as the mass number stays the same but proton number changes, this is specifically beta minus as a neuron changes into a proton

As the air temperature increases, with no addition of water vapor to the air, the dew point will ____. a. remain the same b. increase c. decrease d. become equal to the air temperature

Answers

Answer:

Option (A)

Explanation:

A dew point is usually defined as the specific temperature at which the air gets cooled in order to undergo complete saturation with water vapor. This refers to the condition when the relative humidity becomes 100%, and with progressive cooling, it results in the process of condensation, thereby giving rise to the formation of dew.

In a condition, where there is increasing air temperature and no addition of water vapor, the dew point will eventually remain the same. It is because there is not enough water vapor present in the air for the condensation process to take place and form dew.

Thus, the correct answer is option (A).

Final answer:

The dew point would remain the same when air temperature increases without any additional water vapor. The dew point is dependent on humidity and not on the air temperature. Hence, increase in air temperature with no extra water vapor will leave the dew point unchanged.

Explanation:

Dew Point and Air Temperature

The dew point is the temperature at which air becomes saturated with water vapor after cooling without changing its pressure or moisture content. It's significant in understanding weather and climate patterns. If the air temperature increases with no additional water vapor introduced to it, the dew point would remain the same.

This is because the dew point depends on the humidity or water vapor content of the air, not the air temperature. Thus, without the addition of more water vapor, the amount of water the air can hold at saturation stays the same, therefore the dew point remains the same.
