← ScienceWhich outcome results inside a pressure cooker when water transitions to steam beyond the set pressure?
A)The relief valve repeatedly vents steam✓
B)Water boils at a progressively lower temperature
C)Food cooks unevenly due to pressure gradients
D)Internal pressure increases beyond cooker's limit
💡 Explanation
When water transitions to steam beyond the set pressure, the relief valve activates because the increased vapor pressure exceeds the spring force, causing it to open and vent. Therefore, the valve repeatedly vents steam, rather than lower boiling temperature, uneven cooking, or exceeding the equipment limit, which are prevented by the valve.
