Your hair stands up when you remove your hat in cold, dry weather because of the difference in temperature and humidity. When you wear a hat, it traps heat and moisture close to your scalp, causing your hair to lay flat. Removing the hat exposes your hair to the cooler, drier air, causing it to stand up due to static electricity and the cuticle of the hair strands reacting to the changes in environment.

Why does your hair stand up in a cold dry day?

When two things rub together (like your hair and a hat) electrons can move from one thing to another. Your hair has picked up extra electrons all have the same charge. This causes your hair to repel against each other because like charges repel one another. The furthest any hair can get from another hair is to stand straight up.


When you brush or comb your hair vigorously on an extremely dry day your hair strands on end because?

this is due to static electricity building up in your hair when you brush or comb vigorously on a dry day. The friction from the brushing or combing can cause electrons to transfer between your hair strands, creating an imbalance of charge that makes your hair stand up. Using a moisturizing hair product or a humidifier can help reduce static electricity in your hair.


If you take a cold can of juice from the refrigerator on a hot day. Predict whether condensation or evaporation will take place on the outside of the can. Explain.?

Condensation will likely occur on the outside of the cold can when taken out from the refrigerator on a hot day. This is because the cold surface of the can will cause the water vapor present in the warmer air to cool down and condense into droplets on the can's surface.


Why is my breath cold when I exhale on a cold day?

When you exhale on a cold day, your breath appears cold because the warm air from your lungs meets the cold air outside, causing the water vapor in your breath to condense into tiny droplets, creating a visible mist.


Why does a metal bench feel cold on a cold day?

Metal is a good conductor of heat, so on a cold day, the metal bench quickly loses heat to the environment, making it feel cold to the touch. Your body also conducts heat to the metal, causing it to feel cold as it draws heat away from your body.

Why does your hair stand on end when you take off your hat or a cold dry day?

When you take off your hat, you hair stands on end because of static electricity. Basically, the friction from your hat being removed causes the hairs to lose some electrons and become positively charged. Like-charges repel, so all of the positively charged hairs try to get as far away from each other as possible. This is why it stands on end. When you are cold, your hairs stand up to trap air. Air is a very good insulator, so the hairs trap pockets of it in an attempt to keep you warm. They stand up because little muscles under the skin attached to each hair (called hair erector muscles) contract, pulling the hairs upright.
