Temperature

Consider the following statements regarding a thermocouple. (A) The neutral temperature does not depend on the temperature of the cold junction. (B) The inversion temperature does not depend on the temperature of the cold junction.

In a thermocouple, the temperature of the cold junction and the neutral temperature are -40^(@)C and 275^(@)C respectively. If the cold junction temperature is increased by 60^(@)C , the neutral temperature and temperature of inversion respectively become

The linear equation that converts Fahrenheit (F) to Celsius (C ) is given by the relation, C=(5F-160)/(9) . (i) If the temperature is 86^(@) F , what is the temperature in Celsius ? (ii) If the temperature is 35^(@) C, what is the temperature in Fahrenheit ? (iii) If the temperature is 0^(@) C, what is the temperature in Fahrenheit and if the temperature is 0^(@) F, what is the temperature in Celsius ? (iv) What is the numerical value of the temperature which is same in both the scales ?

A room is heated by a radiator that has a constant temperature T (unknown). When the outside temperature is 260 K, the room temperature is 300 K. However, when the outside temperature drops to 240 K, the room temperature is only 290 K. Estimate the radiator temperature T.

A Carnot engine whose low-temperature reservoir is at 350 K has efficiency of 50%. It is desired to increase this to 60%. It the temperature of the low-temperature reservoir remains constant, then the temperature reservoir remains constant, then the temperature of the high-temperature reservoir must be increased by how many degrees?
