The pressure exerted by a gas in a container depends on?

When there are more collisions between the particles and their container, the pressure rises.

Temperature. The more the temperature, the more the kinetic energy transferred resulting into giving particles more energy to successfully collide with each other at a faster rate and with the container.Number of gas particles inside the container. The more the particles, the more the pressure, the more the particles shall collide with each other and with the container. Thus pressure increases with the number of gas particles.

What are the options? physical property can be color, smell, opacity, viscosity, density, infra red spectrum, melting and boiling points, attraction and repulson to magnets, etc.
