Three possibilities: 1. The heater is plugged with rust. 2. The radiator cap is not maintaining adequate pressure in the system. Raising the pressure prevents boiling. Rad caps contain springs that weaken with use. 3. The coolant contains too little antifreeze (too much water) and the thermostat is stuck open. Flush the system, replace the thermostat and rad cap and refill the system with 70% propylene glycol and 30% water. (Not ethylene glycol - when it spills it poisons animals.) If the problem persists replace the heater core.

Does it take more heat to heat water or to boil water?

It takes more heat to boil water than to simply heat water. Unless the water is already at its boiling point.

What would happen if i don't top up with coolant?

You'd have no heat or air and radiator would boil over causing vehicle damage.

Why does the water in a car radiator sometimes boil explosively when the radiator cap is removed?

Because when the cap is removed the liquid inside wants to start cooling itself. The heat energy is released by boiling.

What material will boil water the fastest?

The material that will boil water the fastest is metal. Metal is an excellent conductor of heat and will heat the water up quickly.

Why is heat needed to boil water?

Because heat changes the temperature of the water

How does the heat energy get from the hot water to the outside of the radiator?

The hot water is in contact with the metal casing of the radiator, so that metal radiator takes some heat from the water. The heat then passes from the inside metal of radiator to the outside metal of the radiator through convection. The outside metal of the radiator then passes it to the air that is blowing by it outside.

How would a microwave oven heat ice versus liquid water?

The actual process of heating would be exactly the same. Microwave energy would begin to excite molecules of water, making them move more quickly and heating them up. Eventually the ice would melt, then boil. The water would heat up then boil.

How can heat change water?

Heat can make water boil and turn to the gas form.

What cleans and purifies water?

Why does it take longer for a gallon of water to boil than a pint?

To boil water a quantity of heat must be added to the water. If there is more water it requires more heat be added. The source of heat can only produce so much heat in a given period of time. So it takes it longer to produce the greater amount of heat to boil the greater amount of water.

What is radiator in case of heat engine?

Radiator is a device to cool the heat engin using water as a coolent

Can you heat the water in satellite?

Yes. Just like astronauts can heat air in a satellite you can heat and boil water.

What makes liquids boil?

Heat can make water boil, like when you put a pot of water on the stove on high!

Can water boil in a solar oven?

Since water is transparent it does not absorb sunlight well, however, you could heat the container that the water is in (especially if it is an opaque container, not a glass container) and then the heated container would heat the water. A solar oven can easily produce enough heat to boil water. If you are not careful it might produce too much heat, and melt the pot.

How does heat get from inside the boiler to the wall behind the radiator?

Conduction of heat energy from the source to the water in the boiler. A pump moves the hot water to the radiator.The heat radiates out from the radiator to the air, where convection then circulates it through the room.

Does cotton boil?

Actually, you can boil liquids, and cotton is not a liquid. If you apply heat to cotton, it would burn before it would boil.

Why does water with oil boil faster than plain water?

because the oil makes the water have more heat which makes the water boil fast.

What does latent heat causes?

Latent heat has the ability to do something in a given time period. Take a water heated radiator, latent heat has the ability to make the radiator warm or hot according to the temprature of the water. It will continue to do this until the water stops flowing through the radiator and the radiator begins to cool.

How long does water have to boil to become sterile?

the water will not sterilize if you boil the water! the water still has bacteria in the water even if you heat it up; that's because some bacteria is heat resistant and will not die through the process.

Why would the antifreeze on a Saturn SL2 heat up and boil over when starting and stopping in local traffic?

Make sure the radiator fan is working. Your thermostat is broken.

What is the effect of the time it takes to boil 16oz of drinking water by varying the temperature of the heat source?

If you increase the temperature of the heat source, you decrease the time it takes to boil the water.
