Compare and contrast the following types of solutions: 

the active material in a helium-neon laser (glows like a neon light),bronze (copper-tin), cloudy ice cubes,and ginger ale.

Helium-neon laser:

Helium neon laser is a type of gas laser in which a mixture of helium and neon gas is used as a gain medium. Helium gas is also known as He-Ne laser.(is a gas-gas)

Bronze:Metal alloy (solid-solid)

Cloudy ice cube:(solid-gas)
