The radiator cap of an automobile engine is designed to maintain a pressure of approximately 15 lb/in2 above normal atmospheric pressure. How does this help prevent the engine from "boiling over" in hot weather? Select all that apply. O Boiling occurs when the vapor pressure equals the surrounding pressure. O Vapor pressure increases with increasing of temperature. O Vapor pressure decreases with increasing of temperature. O The boiling temperature decreases with increasing of pressure. O The boiling temperature increases with increasing of pressure. O None of these.
