Write any three uses of Neon.

Neon Signs: Neon gas is widely used in creating bright, colorful signs and advertisements. When an electric current passes through neon gas, it emits a distinctive red-orange glow, making it perfect for eye-catching signs seen on storefronts, billboards, and cityscapes.
Neon Lighting: Beyond signs, neon is used in lighting applications, particularly in specialized lighting designs for art installations, architectural accents, and interior decor. Neon tubes can be shaped into various forms and colors, offering unique lighting solutions for both commercial and residential spaces.
Cryogenic Refrigeration: Neon is often used as a cryogenic refrigerant in applications where extremely low temperatures are required, such as in scientific research, medical imaging equipment like MRI machines, and certain industrial processes. Its low boiling point and inert nature make it suitable for maintaining stable, low-temperature environments.
