Does cold water boil faster than hot water Reddit?
Yes, boiling hot water takes longer than boiling cold water. The difference is due to the greater amount of energy required to raise the temperature of hot water, which is approximately a 1.5% difference in boiling time between hot water and cold water.
If you’ve been wondering if cold water boils faster than hot water, the answer is yes! The relationship between boiling temperature and boiling speed has been the topic of much debate among scientists for decades, as some claim that boiling is fastest at temperatures around 212°F (approximately 100 degrees C) while others claim it’s fastest at room temperature.
How fast does water boil Reddit?
The boiling time of water is dependent on the temperature. The boiling point of water is 212°F at sea level, which means that the water boils when the temperature of the water reaches 212°F.
The boiling point of water decreases as you go up in altitude, so boiling water at a higher elevation takes longer than boiling water at sea level. The boiling point of water is also dependent on the amount of energy imparted to the water when it’s heated. The boiling point of water is 212 degrees Fahrenheit (100° Celsius).
This is the temperature at which water will turn to steam. Water boils at the same rate regardless of whether it's hot or cold. A pot of water that is sitting at room temperature will take the same amount of energy to come to a boil as will water that's sitting in a hot spring.
How does cold water boil faster than hot water Reddit?
It’s not that cold water boils faster than hot water, it just takes less energy to bring a cup of boiling water to a boil than a cup of ice cold water. If both are at the same temperature, hot water boils at 212 degrees while ice cold water boils at 0 degrees. However, hotter water takes longer to reach boiling point than ice cold water.
A simple example of the difference between boiling hot water and boiling cold water is the time it takes for a pot of water to boil. The hot tap is around 140 degrees Fahrenheit and the cold tap around 70 degrees, so let’s take a look at how the boiling temperatures impact the boiling time.
If we use hot water, the boiling time is reduced to around 20 seconds. If the water is just starting to boil, it will take about 15 seconds.
This is because hotter water can get
Can hot water boil faster than cold water Reddit?
Hot water boils faster than cold water because hot water’s vapor pressure is in contact with the boiling water, causing it to increase rapidly. In contrast, boiling room temperature water usually needs about 10 minutes to reach a full boil. Hot water boils faster than cold water if the hot water is above 212 degrees Fahrenheit.
This “boiling point” of water is called the “saturation temperature”. If you pour boiling water on a cold pot of water, the hot water will take longer to boil than the cold water, since it has to warm up to the boiling point.
Does water boil faster at room temperature Reddit?
Hot water does indeed boil faster than cold water, but the temperature of the water has little effect on boiling time in the kitchen. If you want to save energy and time, use cold water for most of your boiling. Water boils at 212 degrees Fahrenheit at sea level. If you live at higher elevation, your water boils at a lower temperature. But whether you have hot or cold water boiling, it will boil faster at higher temperatures. The specific boiling point of water is dependent on the amount of dissolved gases and impurities in the water.
