how does altitude affect the boiling point of water
High-altitude cooking At sea level water boils at 100°C. For each 500 ft (~150 m) increase in elevation, the boiling point is lowered by 0.5°C. For 8,000 ft (~2500 m) elevation, water boils at 92°C. Boiling as a cooking method must be adjusted or alternatives applied. Vegetables and some starches will simply take longer to cook while rice and legumes (beans) need a pressure cooker. Pasta will need a pressure cooker.[1]
Boiling Lake The Boiling Lake is situated in the Morne Trois Pitons National Park, Dominica's World Heritage site. It is a flooded fumarole 6.5 miles (10.5 km) east of Roseau. It is filled with bubbling greyish-blue water that is usually enveloped in a cloud of vapour. The lake is approximately 200 feet (61 m) to 250 feet (76 m) across. Dominica's Boiling Lake is the second-largest hot lake in the world. The largest is Frying Pan Lake, located in Waimangu Valley near Rotorua, New Zealand.
