Does cold water boil faster?

In this brief guide, we’ll address the search query: “Does cold water boil faster?” Also, we’ll explore how water can boil faster, what precautions to take when boiling water, at what temperature you should drink water, and how to treat burns inflicted by boiling water. 

Does cold water boil faster? 

No, Cold water does not boil faster than water that is at room temperature. Boiling water requires elevating the temperature to a degree which will achieve the same pressure as the gas above it. 

At sea level, water boils at 100°C and as altitude increases it may vary a few degrees below, due to air pressure decreasing as altitude increases. As a result, in some places above sea level water may boil at over 90°C but beneath 100°C.

Cold water has a lower temperature than warm or room temperature water, ergo it will require more energy provided as heat to raise the temperature to a boiling point, and for a slightly longer period.

Additionally, the speed at which water boils does not only depend on the temperature it has, but also its volume. Naturally, larger volumes of water take more time to boil than smaller volumes.

How can I boil water faster? 

There are a few things you can do to boil water faster, these include

  • Starting with water that has a warmer temperature
  • Using a small volume of water to heat it up
  • Cover the pot or kettle with a lid to increase the pressure and quickly raise the temperature
  • Heat the water in a small kettle, as the larger a kettle is, the more heat and exposure it will need to be reach hotter temperatures
  • Use a wide, shallow surface to increase the exposure area, and thin out the water’s volume so that it absorbs heat more readily

What precautions should I take when boiling water? 

When boiling water, you should always be mindful to do it in an appropriate receptacle. This means you should avoid using kettles that are too small for large volumes, as the water may simmer and eventually boil over the edges, spilling onto the gas burners or heating coils. 

For this reason, you should also always be vigilant if you’re boiling a kettle, and never leave hot water unsupervised. 

Also, you should always use kettles and pots with proper handles that are isolated from the heat, if this is not possible, wear oven mitts to grasp these kettles by the handles and avoid burns.

To prevent accidents, never leave children unsupervised near a kettle of boiling water. Children should not play in a kitchen where you’re boiling water or near other sources of heat that may cause severe burns.

If letting the water cool down isn’t an option, pour down the drain and avoid using it to water plants or any other method of disposal that isn’t the drain.

At what temperature should I drink hot water? 

The hottest temperature people are advised to drink any beverage is 65 degrees Celsius.

For obvious reasons, you should not drink hot water. Water should be ingested cool or most warm. Drinking water that is boiling can cause severe damage to your mouth, to your throat, esophagus, and stomach.

These lesions may not only cause discomfort, But may also lead to more serious problems such as ulcers and infections, that may require hospitalization and specialized care. 

How can I treat burns inflicted by boiling water? 

Depending on the severity of the burns you may be able to treat them at home with topical ingredients such as aloe, and steroid cream.

Mild, shallow hot water burns, also known as scalds, can be treated by immediately removing the affected area from the source and flushing it with cool, running water. 

Any clothes or garments such as jewels should also be removed to finish removing any sources of heat from the affected skin.

Avoid applying ice or ice water as this will worsen the damage to cells by exposing them to yet another radical temperature change.

If the skin remains intact, you can cover it with a piece of plastic cling wrap. This will prevent desiccation and crackling.

If the pain is severe, you should address it with over the counter analgesics such as Tylenol or ibuprofen.

If the burns however are severe, such as being larger than 10 cm, or have severely affected the region because it is blistering crackling or discoloration you should see a doctor immediately.

Other serious symptoms of burns include signs of shock such as nausea, lightheadedness, chills, weakness or other signs of concern.

Additionally if you have a skin condition that requires specialized treatment, or if you have an underlying metabolic condition such as diabetes or are immuno depressed you should also see a medical professional, who will properly treat and dress your severe burn, to reduce the risk of sepsis.

If you have a severe scald we encourage you to see an ER doctor and avoid self-medicating or using home remedies to address the symptoms as this may worsen the nature of the burn and result in more complex treatment being necessary.

We urge our readers to always be mindful if they’re cooking or otherwise manipulating hot water, to avoid accidents, and always prioritize their safety.
