A weather balloon containing gas rises through the atmosphere. The temperature of the gas is assumed to remain constant.
The table below shows readings of the pressure of the gas inside the balloon and its volume.
Three of the rows in the table are correct, and one row is not correct.
| pressure / kPa\text{kPa}kPa | volume / cm3\text{cm}^3cm3 | |
|---|---|---|
| A | 240 | 3.0 |
| B | 180 | 4.0 |
| C | 150 | 5.0 |
| D | 120 | 6.0 |
Which row is not correct?
