Multiple Choice
A Galileo thermometer consists of a cylinder filled with a known solution and several sealed glass bulbs partially filled with water. Each bulb effectively acts as an isolated system. If one of the bulbs has the same density as the solution at 25 °C, how will its position and the density of the solution change as the temperature of the solution decreases from 25 °C to 20 °C? 
A) The cylinder solution density will decrease, and the glass bulb will sink.
B) The cylinder solution density will decrease, and the glass bulb will float.
C) The cylinder solution density will increase, and the glass bulb will sink.
D) The cylinder solution density will increase, and the glass bulb will float.
