How are particles involved in the heat conduction process?
Each individual particle on the surface of an object is involved in the heat conduction process. An object with a wider area has more surface particles working to conduct heat. As such, the rate of heat transfer is directly proportional to the surface area through which the heat is being conducted.
Why is my blower motor only working at high speed?
The first thing that needs to be determined is the type of noise that is present and the possible sources. Rattling or knocking noises while… The blower motor only working on high speed is a common symptom of a failing blower motor resistor; but the fact the radio stopped working at the same time is unusual.
How does the rate of heat transfer decrease over time?
Over the course of time, the rate of heat transfer is decreasing. Initially heat is being transferred at a high rate as reflected by the steeper slopes. And as time progresses, the slopes of the lines are becoming less steep and more gently sloped. What variable contributes to this decrease in the heat transfer rate over the course of time?
Which is part of the two phase heat transfer system?
Condensers and Boilers Heat exchangers using a two-phase heat transfer system are condensers, boilers and evaporators. Condensers are instruments that take and cool hot gas or vapor to the point of condensation and transform the gas into a liquid form.
What happens to air when it is heated?
A more significant example of both volume and pressure increasing would be a rubber balloon. Heating air in a balloon increases both pressure and volume, since, while the balloon is elastic and does expand, it also provides some resistance to that expansion.
Why is the heater in my car blowing out cold air and not?
The problem with the heater on the Vauxhall Corsa (as well as the Renault Clio) is often that there is no power from the heaters at all. This issue has nothing to do with cold air coming out instead of heat. This loss of power is also a common issue on the Renault Clio.
Why is the air coming out of my Furnace cold?
You can hear the furnace running, and you can even feel air coming out of the registers. But it’s not hot air coming out, it’s cold! Well, it’s not COLD cold, it’s just room temperature. As if the furnace is just recirculating the air in your house without actually heating it. Which is probably exactly what’s happening.
Why does my upstairs air vent not work?
I’ve noticed that the basement and main floor receive a lot of heat and air conditioning, but the upstairs does not get much air force out of the vents. If I keep the bedroom door closed during the day, I will notice at least a 10-degree difference in temperature.
