Describe Chemical and physical changes of ice water placed in the refrigerator

1 answer:

6 0

So in a chemical change, the product would loses its properties, would form new products and would not be easily reversed.

In a physical change, the products WILL NOT lose any of their properties, WILL NOT form any new products and WILL be easily reversed.

Talking about Water turning to ice I would say it’s all about physical change and not chemical change.
But I would suggest you to either make a research about it or ask your teacher :))

Zanzabum

Answer:

57.8kg

Explanation:

Potential energy is given by:

$U =mgh$

Where U is potential energy, m is mass, g is acceleration due to gravity, and h is height. Using this equation:

$3400=m(9.8)(6)\\3400=58.8m\\m=57.8kg$
