How long does it take to heat one liter of water from a heat source?

It depends on the how many degrees you wish to change the water and the wattage of the heater. Obviously a 1500 watt heater will do it faster than a 1000 watt heater. You might want to begin by looking at the heat transfer formula: heat in joules equals mass times change in temperature times specific heat of the material (water in this case).

When water changes from a liquid to a gas heat and energy do what?
When water changes from a liquid to a gas, it is evaporating or boiling. The "heat and energy" of the water molecules increases in the gaseous state. In fact, water molecules must pick up energy to change state from a liquid to a gas. Water molecules that are free to move as a gas have more kinetic energy than water molecules in a liquid form (as long as the liquid is not pressurized). The "heat and energy" of the H2O molecules that are now a gas is higher than that of liquid water.It should be noted that the thermal energy (heat) necessary to cause water to change state and become a liquid must come from somewhere. In evaporation, the energy necessary for the water molecule to escape from the liquid comes from the liquid. The liquid cools. We know that if we wet our finger and blow on it, it feels cool because evaporating water cools liquid water from which it escapes. That evaporating water has taken energy from the liquid water.In the case of boiling, water molecules take energy from liquid water, but the liquid water might not be cooling. It probably isn't as that liquid water is having thermal energy (heat) pumped into it by a heat source of some kind. Turn on a burner or element on the range under a pan of water and the water will begin warming until it's boiling. As water boils off, it is taking thermal (heat) energy with it, but the remaining water doesn't cool down as the heat source continues to add more thermal energy.
How does geothermal energy converted in to useful form?
Except in places like Iceland which has very hot underground water most geothermal energy is low grade- it is obtained from underground water or from the earth. Passing water through a long tube to this source allows it to heat up by two or three degrees or more. This heat can then be passed through a heat pump which acts just like a refrigerator in reverse. Heating coils from this are then used in central heating systems and are most efficient as underfloor heating systems as these do not have to be very hot.
How long does it take to fill up your well once it has gone dry?
As long as it takes for the aquifer to recharge. The well will not be supplied with water until the water table rises again, since the well forms a cone of depression in the aquifer. (Think about drinking maple syrup through a coffee stirrer). That could be as long as, say, until the cows come home.
How long does it take to increase one degree Celsius in temperature?
That depends on the material or substance or object being heated, the heat source, the current temperature of each, the specific heat capacities of each, and several other factors. There is no rate that works in general.
How do clouds absorb water from the sea?
The sun evaporates water from the Earth and it turns into water vapour. Water vapour rises up into the sky and forms clouds. When the clouds get heavy (means a lot of evaporation), water falls form the sky as rain. The water comes from the clouds. (clouds are not gases. They are solids)
How long does it take for water to boil at Fahrenheit?
The time required to get water to boil depends upon the water initial temperature, the water mass, the nature of the heat source, the net heat transfer rate to the water, and the local barometric pressure.
What does evaporation of the sea water do to the hurricane?
Evaporation of sea water does absolutely nothing for a hurricane except provide water vapor. When the water vapor turns back to water in the form of rain it gives off heat. Hurricanes are massive heat engines. As long as they have water vapor to turn into heat they can continue blowing along. Without water vapor, the hurricane has no source of heat.
How long can a one-and-a-half year old corn snake live without food water or a heat source?
They cannot go without a heat source. The temperatures must be consistent or they will die.
How much water is in a liter?
A liter. This is rather like asking "how long is a 1 foot piece of string."
How much water is a liter?

How long to heat 500 liter water with 3kw element?
Specific Heat of Water = 4.1813 kJ/l/K If starting temperature is say 10°C - 500 Litres * 4.1813 (100°C - 10°C) = 188158.5 kJ 188158.5kJ / 3kW = 62719.5 Seconds = 17.42 Hours
Why does water take so long to warm up?
The specific heat of water determines how much energy is needed to heat water.
What geographic regions would be the best absorber of heat energy?
The equator is probably the best region. Water takes a long time to absorb heat but retains it longer and the place that gets the longest exposure to the heat source (sun) is the equator.
How long do you heat water to get 98.6 degrees?
depends on the amount of water
How long do you have to wait for your plaster to set until you heat your new jacuzzi?
If there is water in it you can heat it.
1 liter of 20 degree water is mixed with 1 liter of 20 degree water what is the temperature?
2 liters of water at 20 degrees, provided the mixing was not too vigorous and didn't last too long.
My Car heater doesn't blow heat immediately when car is started?
You can not get heat from cold water, The engine has to run long enough to get the water in the engine HOT. That is were you get heat from HOT WATER-- Coolent
