La resistencia de un termómetro de platino es de 6Ω a30°C. Hallar su valor correspondiente a 100°C, sabiendo que el coeficiente de temperatura de resistividad del platino vale 0,00392°C^(-1).

Aheat engine that operates on a carnot cycle has an efficiency of 0.420 when its low-temperature reservoir is at 10 ∘c.part aby how many degrees celsius must you increase the temperature of the high-temperature reservoir to increase the efficiency to 0.600 if you continue to use the same low-temperature reservoir?
