you have a blown head gasket
Heat from the engine causes liquid to expand. It used to overflow onto the ground if it caused enough pressure to open the radiator cap. The overflow tanks were installed to automatically catch and return the coolant to the cooling system.
In a Car: A tank to hold "overflow". When fluids heat up, they expand, and like radiator fluid, they need a place to go until they cool. Some cars keep these under some pressure, and if there is a leak, then an engine light will now come on. In the older cars, a leak in this tank would be a minor problem because you'd loose fluid when it leaked out of the overflow.

The heat of the lamp causes the fluids to heat and expand. The two materials are of different thermal properties and are immiscible.The word you seek is convection.
FRICTION
Can a bad heatercore cause antifreeze to come out overflow jug. And heat go off and on.
Friction
Wrong, transfer of heat by conduction does take place in fluids.
Wrong, transfer of heat does take place in fluids. In fact it can take place more efficiently in fluids than in solids because convection is possible in fluids.
Prolonged exposure to high humid temperatures, loss of fluids/ dehydration without being replenished causes the body to go into shock.
