Answer:
Option (1)
Explanation:
The incomplete combustion of fossil generally occurs when there is less amount of air or oxygen. This incomplete combustion leads to the production of carbon monoxide and carbon along with water. It does not release any carbon dioxide.
The reaction that represents an incomplete combustion is-
Hydrocarbon (fossil) + oxygen (O₂) → Carbon Monoxide (CO) + carbon (C) + water (H₂O)
.
This reaction releases this Carbon monoxide which is a very poisonous gas. This gases are trapped in the lungs and it creates difficulty for the blood to carry oxygen. This is the reason why the complete combustion of fossil is more preferred compared to the incomplete combustion.
Hence, the correct answer is option (1).

Answer:
5,778 K
Explanation:
The core of the sun is so hot and there is so much pressure, nuclear fusion takes place: hydrogen is changed to helium. Nuclear fusion creates heat and photons (light). The sun's surface is about 6,000 Kelvin, which is 10,340 degrees Fahrenheit (5,726 degrees Celsius).
