Answer :
To determine the temperature of the middle layer of the Sun's atmosphere (the chromosphere), we can use the typical temperature range given for this layer. The chromosphere has a lower temperature of approximately [tex]$6000^\circ \text{C}$[/tex] and an upper temperature of about [tex]$20000^\circ \text{C}$[/tex].
The average temperature can be calculated using the formula:
[tex]$$
\text{Average temperature} = \frac{\text{Lower bound} + \text{Upper bound}}{2}
$$[/tex]
Substituting the given values:
[tex]$$
\text{Average temperature} = \frac{6000 + 20000}{2} = \frac{26000}{2} = 13000^\circ \text{C}
$$[/tex]
Thus, the chromosphere, which is the middle layer of the Sun's atmosphere, has an average temperature of [tex]$13000^\circ \text{C}$[/tex].
The average temperature can be calculated using the formula:
[tex]$$
\text{Average temperature} = \frac{\text{Lower bound} + \text{Upper bound}}{2}
$$[/tex]
Substituting the given values:
[tex]$$
\text{Average temperature} = \frac{6000 + 20000}{2} = \frac{26000}{2} = 13000^\circ \text{C}
$$[/tex]
Thus, the chromosphere, which is the middle layer of the Sun's atmosphere, has an average temperature of [tex]$13000^\circ \text{C}$[/tex].
