A constant-volume gas thermometer is used to measure the temperature of an object. When the thermometer is in contact with water at its triple point (273.16 K) the pressure in the thermometer is 8.500 × 104 Pa. When it is in contact with the object the pressure is 9.650 × 104 Pa. The temperature of the object is:
A. 37.0 K B. 241 K C. 310 K D. 314 K E. 2020 K
