- A2] The figure shows a copper disk of radius r and thickness r, with a hole through its centre of radius a: Find an expression for the volume of the copper. b) Find an expression for the increase in temperature of the copper AT if it is supplied with an amount of heat Q at constant pressure. The density and specific heat (heat capacity per unit mass) of copper at constant pressure are PCu and ccu respectively. (You should treat these quantities as constants even though thermal expansion will slightly reduce the density, for example). c) of the disk AA/A when its temperature increases by AT, if the coefficient of linear expansion of copper is aCu- (change in dimension)", such as (Ar). Find an expression for the fractional increase in area of the top surface You should ignore terms of the orderIf temperature is the property of a substance that corresponds to the average KINETIC energy of its particles then what is the property of a substance that corresponds to the average POTENTIAL energy of its particles?

- Don't use chat gpt It Chatgpt means downvote4) A ground source heat pump heats a building by extracting heat from the ground and pumping it into the building. Define: Qc = heat extracted from the ground, Qn= heat pumped into the building, W = electric energy used by the heat pump, Tc= temperature of the ground, T = temperature of building (Qc, Qn, and W are positive by definition). Assume Tr > Tc. a) Draw a diagram showing energy flow in and out of the heat pump. b) Write a general expression for the change AS in the entropy of the "universe", that is the heat pump plus the cold and hot reservoirs, in terms of the quantities defined above. Now assume ideal (reversible) operation, and take Te= 10 °C and Tp= 20 °C. What is the coefficient of performance (ČOP) of the heat pump? By what factor would this change if we had Tc = 0 °C instead?Review | Seals may cool themselves by using thermal windows, patches on their bodies with much higher than average surface temperature.
