To find the volume of the smaller cylinder you will need to determine the scale factor by comparing the 2 cylinders. The scale factor is 1:2. This means that each dimension will be divided by 2 when going from the larger to the smaller figure.
Because volume is a three dimensional measurement, you need to divide 9648 by 2, three times.
9648/2=4824 4824/2=2412 2412/2=1206 cubic inches
The volume of the smaller container is 1206 cubic inches.
The thermometer will not directly indicate 0 °C because the thermometer need time to response. Especially alcohol in glass thermometers, the response time is slower than mercury in glass thermometers
