Question

multiple choice question which of the following is required for sterilization to occur in an autoclave? o steam under pressure o heat only o steam and heat only o pressure only

Explanation:

An autoclave sterilizes by using steam under pressure. Pressure increases the boiling point of water, allowing steam to reach higher temperatures (e.g., 121°C at 15 psi) which effectively kills microbes. Heat alone (lower temp), steam and heat without pressure, or pressure alone can’t achieve proper sterilization. So the correct option is the one with steam under pressure.

Answer:

A. Steam under pressure
