3.3 Particle model and pressure

A fixed mass of gas is sealed in a metal container of constant volume. Table 1 shows the pressure of the gas at four temperatures.

Table: the pressure of a fixed mass of gas in a sealed container of constant volume, measured at four temperatures

Which conclusion is supported by the data in Table 1?

[1]

Doubling the temperature in $∘C^\circ\text{C}$ doubles the pressure of the gas.

The pressure of the gas is directly proportional to temperature in $∘C^\circ\text{C}$ .

The pressure increases by the same amount for each $∘C25\ ^\circ\text{C}$ rise.

The pressure would fall to zero if the gas were cooled to $∘C0\ ^\circ\text{C}$ .
