Yes, water can reach 100 degrees Celsius without boiling if it is under increased pressure. In environments with higher atmospheric pressure, such as in a pressure cooker, water's boiling point can be pushed higher than 100 degrees. This effect allows water to be heated to 100 degrees or more without transitioning to the gas phase.

FAQs & Answers

  1. Why does water boil at different temperatures under different pressures? Water boils when its vapor pressure equals the surrounding atmospheric pressure. Under higher pressure, like in a pressure cooker, this equilibrium occurs at temperatures above 100°C, raising the boiling point.
  2. Can water be heated above 100 degrees Celsius without boiling? Yes, by increasing the pressure around water, it can be heated above 100°C without boiling, as its boiling point rises with pressure.
  3. How does a pressure cooker make food cook faster? A pressure cooker raises the boiling point of water by increasing pressure, allowing the water and steam to reach higher temperatures and cook food faster.
