B 0.50 kW C 12 kW D 20 kW Your answer 43 Cooling water enters the heat exchanger in the turbine hall of a nuclear power station at 6°C and leaves at 14°C. The specific heat capacity of water 4200 J kg-1 K-1. If the rate of heat removal by the water is 6.72 x 109 J per minute, what is the rate of water flow? A kg s-1 B kg s-1 C kg s-1 D kg s-1 Your answer 44 The graphs A D represent different relationships between variables in A level – Physics. The dotted lines mark out equal intervals along the x- and y-axes. Which graph best represents the relationship between the variables and where: x y y is the pressure of a fixed mass of gas in a rigid container x is the temperature of the gas A B C D
