Why does water with salt in it freeze much more slower than water without it ? Explain

Answers

Answer 1
Answer: When you add salt to water, you lower to freezing point of the substance.

So for example, normal water freezes at 0°C. But water with salt in it won't freeze at 0°C, because its freezing point is lowered. 

In answer to the question. It takes longer for water with salt in it to freeze because the substance requires a lower temperature than normal water to freeze.
Answer 2
Answer: The more salt in the water, the lower the freezing point will be. When freshwaterfreezeswater molecules of hydrogen and oxygen have bonded together into a crystalline structure of ice. The presence of salt makes it harder for water molecules to bond to the ice structure, because ice naturally repels salt molecules.

Sometimes clothes removed from the dryer cling together. What kinds of charges are on the clothes ?

Answers

The answer is "opposite charges."

Final answer:

When clothes are removed from the dryer and cling together, it is because static electricity is created from the clothes rubbing together in the dryer. This results in an imbalance of electrical charge on the clothes, with some having a net positive charge and others a net negative charge, which makes them attract and stick to each other.

Explanation:

When clothes are removed from the dryer and they cling together, this is due to the presence of static electricity. Static electricity occurs when materials are rubbed together, causing an exchange of electrons. This exchange results in the materials being electrically charged. In the case of your dryer, the process of tumbling and rubbing the clothes together can strip electrons from the clothes and deposit them on other pieces.

This creates an imbalance in charge, leading to some clothes having a net positive charge and others with a net negative charge. The positively charged clothes are attracted to the negatively charged ones, and this attraction causes the clothes to stick together. The force that brings these different charged clothes together is called electrostatic force. If the clothes are damp, the presence of water molecules can suppress the charge, reducing the static cling.

Answers

The muscles of the body are part of the musculoskeletal system but would not operate without the nervous system providing the impulses that cause the muscles to act. Correct answer: C The nervous system controls all activities within the human body, including the muscles. It sends messages between the brain and the muscles very quickly using nerve impulses (action potentials).

Nervous is the system that provides impulse
