Question 5

Thermometric property of thermocouple is ______.

Question 6

Work transfer between the system and the surroundings______.

Question 7

The resistance in copper winding of a motor is 100ohms at 25 °C. When operating at full load the resistance was found to be 150 ohms. The resistance is related to temperature by following equation.
R_t= R₀ (1+0.0693t) where R₀ is the resistance at 0 °C, T is temperature in °C. Find the temperature of the coil at full load.
