Question

Give reason:

Liquid ammonia is used as a refrigerant.

Answer 1

Reason why liquid ammonia is used as a refrigerant:

• A refrigerant is a chemical compound that acts as a coolant by converting environmental heat to cool air in an air conditioner.
• Liquid ammonia is a widely used refrigerant.
• This is because it can easily undergo liquefaction at room temperature under pressure.
• Additionally, it has high volatility and latent heat of vaporisation.
• Thus, Liquid ammonia is a good refrigerant due to its high latent heat of vaporization, high volatility and ease of liquefaction.
