The time taken for a kettle to boil will vary based on factors such as the power of the kettle, the amount of water being boiled, and the starting temperature of the water. To calculate the time, you can use the formula: time = (energy needed to heat water) / (power of the kettle). This formula takes into account the specific heat capacity of water and the efficiency of the kettle.

A kettle that is watched never boil?
If all you do is watch it, it will never boil.A kettle with no water in it will never boil.The kettle actually won't boil, just the water that is in it.The kettle may seem as if it never boils while you are watching it because the process is about as exciting as watching paint dry.
How does the amount of water put into a kettle affect the time it takes to boil?
The more water you put into the kettle, the longer it will typically take to boil. This is because more water requires more energy to heat up to boiling temperature. Conversely, less water will heat up faster because there is less volume to heat.
What is the fastest way to boil water in the kitchen?
Turn the burner on high. Get two small pots and put the desired amount of water (split in two) into them. Then put lids on them. It also helps to put something with rough edges so the vapor bubbles can cling to the new surface. It works faster if your are on a mountain or somewhere where there is low air pressure. And, since we all know how time goes so slow when we wait for it to pass, don't sit and watch it.
Two similar heater coils separately take 10 min to boil a certain amount of water if both are connected in series time taken to boil the same amount of water will be?
If two similar heater coils are connected in series, the time taken to boil the same amount of water will be longer than 10 minutes. This is because when connected in series, the coils share the voltage and the total power output is divided between the coils, therefore taking longer to heat up the water.
How is speed calculate?
Average speed is calculated by dividing the total distance covered divided by the time taken. Instantaneous speed is calculated as the derivative of displacement with respect to time.
Why does half a full kettle take less time to boil a full one?
That is not possible a full kettle has more water,therefore it will take longer to boil.
How long does a 1.7L kettle of 3kW take to boil?
To calculate the time it takes for a 1.7L kettle with a 3kW power rating to boil water, we can use the formula: time = energy required / power. The energy required to heat 1.7L of water from room temperature (about 20°C) to boiling point (100°C) is approximately 670 kJ. Given that 3kW equates to 3 kJ/s, it would take about 37 minutes to boil. However, in practical terms, it usually takes around 5-7 minutes for a kettle of this size and power to boil water.
How long will it take to boil a kettel of 500ml?
The time it takes to boil 500ml of water in a kettle typically ranges from 2 to 5 minutes, depending on the kettle's wattage and the starting temperature of the water. Higher-wattage kettles boil water faster. Additionally, factors like altitude and the kettle's efficiency can also affect boiling time.
Why putting less water in kettle will help use less energy?
because it takes less time for the water to boil. I f you put more water in the kettle it will take a longer time for it to boil which takes in more energy
How is air pressure relative to sea level?
Air pressure is higher at sea-level, so a kettle will boil quickly. Air pressure lessens the higher one climbs, so a kettle will take a long time to boil on the top of Mount Everest.
A kettle that is watched never boil?
If all you do is watch it, it will never boil.A kettle with no water in it will never boil.The kettle actually won't boil, just the water that is in it.The kettle may seem as if it never boils while you are watching it because the process is about as exciting as watching paint dry.
Why does it a take a full kettle of water to boil longer than a half full kettle?
The more water in the kettle, the longer it will take to reach boiling point. This is why it is wasteful in energy to boil a full kettle if you only want to brew a small cup of tea.
How do you calculate time taken to raise the temperature by 10 degree The question is in the answer section?
To calculate the time taken to raise the temperature by 10 degrees, you would need to know the rate at which the temperature is increasing. This can be determined by dividing the change in temperature (10 degrees) by the rate of temperature increase. The result will give you the time it takes to raise the temperature by 10 degrees.
What are the advantages of an eco kettle?
Until now, conveniently measuring the correct amount of water to be boiled in your kettle has not been easy. It is estimated that, on average, we boil twice the volume of water needed every time. Which means twice as much energy, twice as much time. An eco kettle allows you to boil just the right amount of water every time.
Why does it take longer for a full kettle of water to boil than a half full kettle?
A full kettle of water takes longer to boil than a half full kettle because more water requires more energy to heat up to the boiling point. The greater volume of water in a full kettle absorbs more heat energy before it reaches the boiling point, leading to a longer heating time.
When you boil a kettle twice is the water hotter the second time?
No, the water will not be hotter the second time you boil a kettle. Once water reaches its boiling point at 100 degrees Celsius, it cannot get any hotter unless it is under pressure. Boiling water multiple times will not increase its temperature beyond 100 degrees Celsius.
How do you calculate speed if the time taken is in seconds?
convert the time
