一、高压锅使用过程中为什么要排出锅内的冷空气? 高压锅的原理是:压强增大,液体的沸点升高.但通过实验证明,高压锅内留有不同气压空气时,虽然液体表面气压相同,但温度并不相同. 表一留有不同的气压空气时,温度与压强的关系从下表可知当锅内气压相同时,锅内留有的空气气压越低,温度就越高,所以使用高压锅时要等到锅内气体沸腾,水汽化排出锅内的冷空气后盖上限压阀,以达到理想的温
First, the use of pressure cookers during the process to discharge the cold air inside the pot? The principle of the pressure cooker is: pressure increases, the boiling point of the liquid rises. However, experiments have shown that, when the pressure cooker is left with different air pressure, although the liquid surface pressure is the same, But the temperature is not the same. Table 1 has different pressure air, the relationship between temperature and pressure from the table below shows that when the pressure inside the pot is the same, the lower the air pressure left in the pot, the higher the temperature, so use the pressure cooker Wait until the gas in the pan boils, and vaporize the water to remove the cold air inside the pan and cap the pressure valve to achieve the desired temperature.
