At what temperature does the volume of a gas become theoretically zero?

In order to increase the volume of a gas by $10 \%$,the pressure of the gas should be

Densities of a gas at different conditions are in the ratio $1:2$ and their temperatures are in the ratio $2:1$,then the ratio of their respective pressure is :-

Which of the following represents the correct relationship between the change in density of an ideal gas and the change in temperature?

Which amongst the following options is the correct graphical representation of Boyle's law?

The isobars of one mole of an ideal gas were obtained at three different pressures ($p_1$,$p_2$ and $p_3$). The slopes of these isobars are $m_1$,$m_2$ and $m_3$ respectively. If $p_1 < p_2 < p_3$,then the correct relation of the slopes is
