No. Heat is not affected by gravity. Heat flows from hotter objects to colder objects.
Up. Heat goes up.
The only factor that free convection heat flow depends on is the conductivity of the material. Heat moves toward a cold area and heat it up and the reverse is true for cold, it will cool down something warm.
i can't flow up
Convection currents.
Yes, it is called shivering. This muscle activity releases heat and causes the blood flow to increase.
BOTH
The resistance to the electric flow through the wire coil causes heat
To heat something means to bring the temperature up and to cool something means to bring temperature down. Hence the terms "Heat Up" and "Cool down". We actually do not need to add the up or down, as heat in itself means to rise, and cool means to lower. So instead of saying "I need to heat my food up", one could just say, " I need to heat my food".
UP- flow, down-flow and Horizontal
Because the particles, when they heat up, they vibrate and heat up, and when they stop heating up, well, it takes them a while to stop vibrating, and cool down.
The vehicle will have something called a "Thermostat Event". There is a scensor on the engine that will sense that the engine is heating up and open a valve that lets the coolant flow freely though out the whole system. -Rudolf Diesel
choices are: The cold will flow from the metal into the hot water, causing the hot water to warm up and the metal to cool down. b. The energy from the hot water will flow into the cold metal, cooling the water down and heating up the metal. c. The cold will flow from the metal into the hot water, causing the hot water to cool down and the metal to warm up. d. The metal will cool down because the specific heat of water is high.
