What type of changes does the ball experience when it is frozen in liquid nitrogen and then dropped on floor?

When a ball is frozen in liquid nitrogen and then dropped on the floor, it undergoes several physical changes:

1. Contraction: Liquid nitrogen has an extremely low temperature, typically around -196 degrees Celsius (-321 degrees Fahrenheit). This causes the ball to undergo rapid and significant contraction. The molecules within the ball lose energy and move closer together, reducing the overall volume of the ball.

2. Brittleness: The freezing process makes the ball extremely brittle. The reduced molecular movement results in a rigid and inflexible structure. As a result, the ball becomes more susceptible to cracking or shattering upon impact.

3. Increased Density: Due to the contraction and reduced molecular motion, the density of the ball increases. The mass remains the same, but the volume decreases, leading to a higher density.

4. Loss of Elasticity: The elastic properties of the ball are greatly reduced or even lost when frozen in liquid nitrogen. The material becomes less able to absorb and store energy upon impact, leading to a decreased ability to bounce or deform without breaking.

5. Reduced Electrical Conductivity: Metals exhibit a decrease in electrical conductivity when cooled to extremely low temperatures. If the ball contains metal components, their electrical conductivity will be reduced, potentially affecting any electronic features or sensors within the ball.

6. Color Changes: Some materials may exhibit color changes or become transparent when subjected to extremely low temperatures. Depending on the composition of the ball, it may undergo subtle or noticeable color shifts during the freezing and dropping process.

It's important to note that these changes may vary depending on the specific material composition and properties of the ball, as well as the precise conditions during the freezing and dropping process.
