A student measured the volume of a sample of air at different temperatures. All measurements were taken at 1 atm. The observations were recorded in a data table.

The Volume of an Air Sample at Various Temperatures :

Temperature (°C)

0, 20 , 40 , 60

Volume (L)

15, 16.1, 17.2, 18.3

variables:

Manipulated:

Responding:

Controlled:

After analyzing the data, the student could conclude that:

A. volume divided by the temperature, in degrees Celsius, is a constant

B. temperature, in degrees Celsius, times the volume is a constant

C. volume divided by the temperature, in Kelvin, is a constant

D. temperature, in Kelvin, times the volume is a constant
