Question

The volume of a gas is directly proportional to its temperature (in Kelvin) at constant

pressure. What does this mean?
As one increases, the other will increase at the same rate. The graph will show a
straight line.
As one increases, the other will decrease at the same rate. The graph will show a
straight line.
As one increases, the other will decrease at the same rate. The graph will show a
inverse line.
As one increases, the other will increase at the same rate. The graph will show an
