Question 1: In areas of enhanced heat flow, geothermal heating can be used to supply heating to homes, either by using ground water directly or by placing a water reservoir at depth. In Iceland, where the average temperature over the year is 4.6ºC, the geothermal flux can be as high as 300 mW m^-2.

If you wanted to be able to supply a home with indoor temperature at 25ºC and water at a temperature of 55ºC, how deep would your reservoir need to be? (1 mark)

Why might Iceland have such a high geothermal flux compared to other areas?

Does high geothermal flux accelerate the melting of ice sheets, why or why not?

A 140litre container is to be used to store heat for a domestic heating system. There are two options for the storage material, lead blocks or clay bricks. Using the data provided determine which is the best option for the system. Lead: specific heat 130J/kgK, density 11340kg/m3 Brick: specific heat 840kJ/kgK, density 2000kg/m3 2. A container holds 0.25m3 of compressed air at 900kPa and 20°C. This is expanded polytropically via a process with n=1.3 to a pressure of 150kPa....
