How does the amount of water put into a kettle affect the time it takes to boil?
the more of an object the more the mass in witch takes more time to heat up.
Does looking at water make it take longer to boil?
No, it only makes it feel longer because you are more aware of the time being taken.
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?
red flower kept in a green light will appear?
What is formula is used to calculate speed?
Distance travelled / time taken to travel the distance
Why do kettles use an alternating current rather than a direct current?
Normal household current is AC not DC. If the kettle was DC what would it plug into? Actually, as a kettle is a purely resistive device it will perform equally well with a DC supply as with AC. Assuming you could plug it into a DC power source of the same voltage as it's AC supply it would boil water in approximately the same length of 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 do you calculate time taken to raise the temperature by 10 degree The question is in the answer section?
The question is : A 2000W electric heater supplies energy to 0.5kg copper kettle containing 1kg of water. calculate time taken to raise the temperature by 10 degree
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
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.
When you boil a kettle twice is the water hotter the second time?
yes its tasty
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.
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 does the amount of water put into a kettle affect the time it takes to boil?
the more of an object the more the mass in witch takes more time to heat up.
How do you calculate speed if the time taken is in seconds?
convert the time
How to calculate retardation?
Retardation = change in vel / time taken
What does a watched kettle or pot never do?
Boil, or so it seems. ............................................................................................................. Yes, that's true. As a saying it means time passes more slowly if you just passively wait for something to happen. If you are active and involved, time will fly.
