Dalton's Law states...

• that at a constant temperature the volume of a confined ideal gas varies inversely with its pressure.
• that the total pressure exerted by the mixture of non-reactive gases is equal to the sum of the partial pressures of individual gases
• how gases tend to expand when heated
• that the density of an ideal gas at constant pressure varies inversely with the absolute temperature of the gas.

Which equation represents Dalton's Law?

• e=mc2
• PV=nRT
• P1/T1=P2/T2
• Ptotal=P1, P2, P3...

density

• a physical property of matter that describes the number of particles of a substance that fits in a unit of volume

• a chemical property of matter that describes the amount of mass a substance has per unit of volume

• a physical property of matter that describes the amount of mass a substance has per unit of volume

Which of the following is not true about gases?

• They spread out to fill their containers
• They have a low density. 
• The particles move very slowly. 
• The volume changes with whatever shape the room is.
