ACTIVITY 17 Volume - Temperature Relationship Defend or refute each of the following statements. State your position and explain your answer by showing the calculations involved. Assume that the pressure and amount of gas are constant. 1. If a sample of gas is cooled from 200 C to 100 C, the volume will decrease by a factor of two. 2. If a sample of gas is heated from 150C to 1500 C, volume will increase by a factor of ten. 3. If a sample of gas is cooled from 273 C to 0'C, the volume will be halved. 4. If a sample of gas is heated from OC to 100 C, the volume will increase a hundred times
