2) Burning and Respiration ​

Answer 1

Answer:

1-

(a) Rusting is a slow process while burning is a fast process.

(a) Rusting is a slow process while burning is a fast process.(b) Rusting takes place in the presence of oxygen and moisture while burning requires only oxygen.

2-

Respiration:

• :It is the process of oxidation of food materials like Amino acids, glucose, fatty acids to ‘carbon dioxide and water’.
• :It is the process of oxidation of food materials like Amino acids, glucose, fatty acids to ‘carbon dioxide and water’.In respiration process energy is released in several stages.
• :It is the process of oxidation of food materials like Amino acids, glucose, fatty acids to ‘carbon dioxide and water’.In respiration process energy is released in several stages.It does not require any ‘external heat’ on the process.

Combustion:

• Combustion:It is the process to form a carbon dioxide and water by burning sugar which helps in the ‘release of energy’ in the form of heat.
• Combustion:It is the process to form a carbon dioxide and water by burning sugar which helps in the ‘release of energy’ in the form of heat.In combustion, energy is released only once.
• Combustion:It is the process to form a carbon dioxide and water by burning sugar which helps in the ‘release of energy’ in the form of heat.In combustion, energy is released only once.It is only done by applying external heat to the sugar molecule to burn.
