Just a quick question. Is there a formula for the coefficient of performance equation for just temperatures. All I have is the outdoor and indoor temperauture. How would I approach that?
Yes, there is such a formula. It generally assumes that the heat pump (or refrigerator) is an ideal Carnot engine (maximum efficiency -- no losses due to friction, etc.)name_ask17 said:Just a quick question.

Do you already have formulas for COP as a function of Qhot and Qcold?name_ask17 said:what is Q? how would i find that.
because in my problem, i literally only have Tc and Th. how do i do that?
The coefficient of performance or COP of a heat pump is the ratio of the change in heat at the "output" (the heat reservoir of interest) to the supplied work.name_ask17 said:when it asks for joules of heat, what specifically is this asking me to solve for?
You absolutely have to convert to Kevlin!and if i use the equation you wrote above, do i have to convert it to kelvin or can i leave it as celcius?
Thermodynamics is a branch of physics that deals with the relationships between heat, work, energy, and temperature.
The first law states that energy cannot be created or destroyed, only transferred or converted. The second law states that natural processes tend to move towards a state of greater disorder or entropy. The third law states that the entropy of a perfect crystal at absolute zero temperature is zero.
Thermodynamics has countless applications in everyday life, including in the design of engines, refrigerators, and air conditioners. It is also used in the study of weather patterns and climate change, as well as in the production of electricity and chemical reactions.
Heat is a form of energy that is transferred from one object to another due to a difference in temperature. Temperature is a measure of the average kinetic energy of the particles in a substance. In other words, heat is the transfer of energy, while temperature is a measure of how much energy is present.
One common misconception is that the laws of thermodynamics only apply to closed systems, when in fact they apply to all systems. Another is that entropy always increases, when in reality it can decrease in certain situations. Additionally, some people may think that thermodynamics only applies to heat, but it also applies to other forms of energy such as work and internal energy.
