Properties of Gases

Properties of Gases

Density of air (outside) = 1.2 mg/mL. Density of air (inside) = 0.88 mg/mL. Properties of Gases. Pressure: the pressure of a gas is caused by the gas particles colliding with the walls of the container. Pressure is always a force exerted over an area. (P = F/A)

What is the difference between the molecules in a cup of water and the molecules in a cube of ice?

What is the difference between the molecules in a cup of water and the molecules in a cube of ice?

What is the difference between the molecules in a cup of water and the molecules in a cube of ice?. A the molecules in water have less kinetic energy. The molecules in the cube of ice are less free to move. The molecules in the cube of ice are moving faster.

Reactions that cause change of oxidation numbers are called redox reactions.

Reactions that cause change of oxidation numbers are called redox reactions.

Reactions that cause change of oxidation numbers are called redox reactions. Element loses electrons → its oxidation number increases → element is oxidized → oxidation reaction. Substance that contains the oxidized element is call the reducing agent.
