Answer : The final equilibrium temperature of the water and iron is, 537.12 K
Explanation :
In this problem we assumed that heat given by the hot body is equal to the heat taken by the cold body.
where,
= specific heat of iron = 560 J/(kg.K)
= specific heat of water = 4186 J/(kg.K)
= mass of iron = 825 g
= mass of water = 40 g
= final temperature of water and iron = ?
= initial temperature of iron = 
= initial temperature of water = 
Now put all the given values in the above formula, we get:
Therefore, the final equilibrium temperature of the water and iron is, 537.12 K
The mass number of an atom is its total number of protons and neutrons. Atoms of different elements usually have different mass numbers , but they can be the same. For example, the mass number of argon atoms and calcium atoms can both be 40.
Chemical process is responsible for the smell of vinegar in an old bottle of aspirin is Hydrolysis of ester i.e. Aspirin.
Aspirin reacts with water leading to the formation of Acetic acid which is a Carboxylic acid derivative.
Aspirin on Hydrolysis forms Acetic acid and Salicylic acid.
The reaction shows up as a fizz when aspirin is added in water.
Aspirin is called Acetyl Salicylic acid and it helps to reduce:
- Inflammation
- Pain
- Fever
- Headache
- Arthritis
- Muscle pain
- Tooth pain
Acetic acid or Ethanoic acid is a colorless liquid. It is an important carboxylic acid. It smells like vinegar.
Acetic acid is used for production of following:
- Vinyl Acetate
- Insecticides
- Rubber
- Acetic anhydride
Salicylic acid is a bitter compound which is colorless. It reduces acne and opens up the skin pores.
