**narrowed it down ! **1. it was observed that the particles of an unknown substance exist as ions under normal conditions. these ions move quickly in random directions. what is the state of matter of the substance? a.) gasb.) plasma2. a postulate of the kinetic molecular theory is listed. postulate: gas particles are extremely small and are far apart. which of the following activities can be used to demonstrate the postulate? a.) observing the ease of pushing the plunger of a capped nozzle syringe containing gasb.) observing colored gas spreading into an inverted jar placed on top of a jar containing the gas3. a hot air balloon has an air vent that keeps the air pressure inside and outside the same. allen observes that a hot air balloon rises up when the gas molecules inside it are heated. which of the following laws is used to understand the behavior of the gas and why? a.) the high temperature makes the gas molecules spread apart according to charles's law because this law describes how a gas will behave at constant pressure. b.) the high temperature raises volume according to boyle's law because this law describes how a gas will behave when the number of moles remains constant.
