Why low temp rise in cooling mode of heat pump?
COULD BE MANY THINGS- NEED MORE SPECIFICS. MOST LIKELY TXV OR CHARGE ISSUE. IF TEMP RISE GOOD IN H/P MODE W/O STRIP OR SUPP. HEAT ADDED MOST LIKELY TXV. IS OA TEMP AN ISSUE THIS TIME OF YEAR? (LOW HEAD PRESSURE) lc
What will happen when heat is added to water that is room temp?
The water will get hotter. Its molecules will move faster, and the temperature goes up.
Why do heat provides heat not cold?
Always heat is transfered from high temp to low temp. So heat bodies radiate heat. When a body is heated up when the temp is higher in body than surrounding heat is transfered
Why is there no further rise in temp. when we heat a liquid at its boiling point?
For a certain interval of time, the temperature does not increase any further when the temperature of the water reaches the boiling point because of the heat energy being added at this point is going into converting the liquid to a vapor (gas). That is to say, all of the energy is going into breaking bonds and overcoming the atmospheric pressure, so none of it goes into increasing the temperature.
Why do heat gives heat than cold temperature?
Beause heat is transfered by high temp to low temp.If a system heats up so that its temperature is greater than atmospheric temperature the systan has high temp than atmospheric temp as heat transfer from high temp to low temp heat radiates from the system.
What happens to the temp of a cup of coffee when a sugar cube is added. Does the temperature increase or decrease and why?
decrease,because the cube of sugar absorb some heat
Can the sun make the temp of an object rise?
yes.
Why is the thermostat reading 10 degrees cooler than the heat is set on?
It is because your thermostat is taking time to warm up. It should eventually rise up to the temp. that you set it as.
What prevents a 98 grand prix not to rise to operating temp?
If the thermostat is broken and stuck open, the engine temp will not rise very fast. Hope this helps "G"
Does the size of the utensils placed in the fridge affect its coefficient of performance?
yes! it will take longer for the system to be at desired temp because it draws the the heat from those added utensils. if the fridge took 4 hours to get to its designed temp and you fill it with room temp products it will roughly take 45% longer to get back down to that temp.
What should supply air temp be for heat pump heating?
With heat pumps supply air temp will vary with outdoor temp. The colder it gets outside the less efficient the heat pump will be (colder supply air).
What happens to solid when absorb or release heat?
when it absorbs heat temp increases if heat sufficient enough then changes into the liquid state if heat is released then the temp decreases if it is high then it gets feezed
