1. 1. Which one of the following is the SI unit of thermodynamic temperature?

   • A. Degree Celsius (°C)
   • B. Kelvin (K)
   • C. Joule (J)
   • D. Degree Fahrenheit (°F)

2. 2. A hot afternoon in Garissa records a temperature of 37 °C. Convert this temperature to kelvin, using T = θ + 273.

   Type your answer (in K) in the lesson.

3. 3. An ungraduated mercury thermometer has a column length of 2.0 cm at the ice point and 22.0 cm at the steam point. When placed in warm milk, the column length is 11.0 cm. What is the temperature of the milk?

   Type your answer (in °C) in the lesson.

4. 4. A cup of hot chai at 80 °C and Lake Victoria at 24 °C are compared. Which statement is correct?

   • A. The cup has the higher temperature, but the lake holds far more total heat energy because it has a much larger mass.
   • B. The lake holds less heat energy because its temperature is lower, and mass does not matter.
   • C. Temperature and heat energy are the same quantity, so the cup has more of both.
   • D. The lake has the higher temperature because it contains more water.

5. 5. What name is given to the apparatus that exposes a thermometer bulb to pure steam when determining the upper fixed point?

   Type your answer in the lesson.
