What temperature on the platinum resistance Wen scale would correspond to a resistance value of 8.43 02? Measured on the gas scale, the same temperature corresponded to a value of 1020°C. Explain the discrepancy. (L.) 9 Explain what is meant by a change in temperature of 1°C on the scale of a platinum Ro resistance thermometer. Ceuse C 0.384 ahm Cheg in res stole Draw and label a diagram of a platinum resistance thermometer together with a circuit in which it is used. Give two advantages of this thermometer and explain why, in its normal form, it is unsuited for measurement of varying temperatures. The resistance Re of platinum varies with the temperature 0°C as measured by a constant-volume gas thermometer according to the equation (c) Explain why the laboratory. (AEB.) Ro Ro(1+8000x0 - x0²) where x is a constant. Calculate the temperature on the platinum scale corresponding to 400°C on this gas scale. (N
