Question

If the sun produces energy by the proton-proton chain, then the center of the sun must have a temperature of at least

a.
104 K
b.
107 K
c.
1010 K
d.
1013 K
e.
1016 K

Answer 1

Answer:

b. 10^7 K

Step-by-step explanation:

The proton-proton chain is the primary nuclear reaction that occurs in the sun, which converts hydrogen into helium and produces energy in the process. The temperature required to sustain this reaction is very high.

According to current scientific understanding, the temperature at the core of the sun is approximately 15 million degrees Celsius (or about 27 million degrees Fahrenheit). This corresponds to a temperature of about 10^7 K, which is option (b).

Therefore, the correct answer is (b) 10^7 K.
