It sounds like either a loose ground or power supply, start by checking the connections at the blower motor............
The specific heat of substance A is greater than that for substance B. If both sample sizes are the same and they both start at the same temperature and equal amounts of heat are added to both these samples, substance A will have a lower temperature than substance B.
My wife had the same problem, no heat when idle and blow cold air.. when driving the heat was fine.. Checked the antifreeze level and it was low.. got it topped off and that has brought the heat back at idle... hope that helps
Until they reach thermal equilibrium - that is, until they both have the same temperature.
heat shield might have came lose if it rattles alot
When driving in summer heat the first priority for the car is making sure the engine doesn't overheat. It is a good idea to use the windows and vents to cool both the driver and engine rather than the air conditioning.
The heat will transfer to the cooler object.
Heat flows from a region of higher temperature to a region of lower temperature. This is known as the direction of heat transfer, which occurs until both regions reach thermal equilibrium.
In a closed system, yes. Both objects will be at the same thermal energy level, and neither will be able to release any to the other. In the real world, this is not the case, heat would continue to dissipate until the object reaches the same thermal energy level as the air around it, approximately.
Heat will flow from the hotter object to the colder one until they reach thermal equilibrium, where they both have the same temperature. This transfer of heat will continue until a balance is reached between the two objects.
Heat will flow from the system at higher temperature to the system at lower temperature until thermal equilibrium is reached. This flow of heat will continue until both systems reach the same temperature.
heat moves from hot to cold, until both objects have the same temperature which is called conduction
So you have no heat? Here are some basic questions: Is your coolant level low? ( not the overflow jug, pop the cap on the radiator) If no, then: flush the heater core. you can find 2 hoses on the firewall that run to a bypass housing. disconnect them both flush one hose at time until water runs clear through both of them. If still no heat, suspect the water pump, very unlikely as there would be some heat while driving but not at idle. and that its not the water pump.
