A student measures the volume of a fixed mass of gas at four different pressures. The temperature is kept constant. Table 1 shows the results.
Table: the volume of a fixed mass of gas at four different pressures, measured at constant temperature
| Pressure in kPa | Volume in cm3\text{cm}^3cm3 |
|---|---|
| 100 | 48 |
| 150 | 32 |
| 200 | 24 |
| 300 | 16 |
Which statement about the results is correct?
The results show that pressure÷volume\text{pressure} \div \text{volume}pressure÷volume has a constant value of 4800.
The results show that pressure+volume\text{pressure} + \text{volume}pressure+volume has a constant value of 4800.
The results show that pressure×volume\text{pressure} \times \text{volume}pressure×volume rises as the pressure rises.
The results show that pressure×volume\text{pressure} \times \text{volume}pressure×volume has a constant value of 4800.
