The answer is heat transfer :D
When sunlight hits your skin, it transfers energy to the molecules in your skin, causing them to move faster and generating heat. This heat is what makes you feel warm when you're out in the sunshine.
Sunlight contains ultraviolet (UV) radiation that penetrates the skin and is absorbed by cells. This energy is converted into heat, which causes the skin to feel warm. Additionally, sunlight triggers the production of melanin, a pigment that helps protect the skin from UV damage.
In direct sunlight, you feel warm because the sun's rays heat up your skin. In the shade, you feel cooler because you are not directly exposed to the sun's rays, so there is less heat reaching your skin.
Sunlight contains energy in the form of electromagnetic radiation. This energy is absorbed by molecules in your skin, causing them to vibrate and generate heat. This heat is what makes you feel warm when exposed to sunlight.
I think it is because when radiation hits your skin, it actually cooks your skin, creating heat that you feel as warmth. Yet, eventually the Sun cooks your skin for to long and burns it, creating what we call, a sunburn.
If it'a tempurtaure is high, it'll feel warm and some cells in ya brain will respond.
Infrared radiation is the electromagnetic wave that makes your skin feel warm. It has longer wavelengths than visible light and can penetrate the skin's surface, causing it to heat up.
Friction
When your skin is in the sun on a summer day, it feels warm because the sun's rays contain ultraviolet (UV) radiation. This radiation penetrates the skin and causes blood vessels to dilate, increasing blood flow to the skin's surface. This increased blood flow is what makes your skin feel warm.
If they hit your skin, then they definitely always do.
A human's skin is normally soft, warm, and smooth. A rooster or chicken's skin will feel bumpy, and coarse.
False. Some objects do have heat, but are not always warm. For example, Jupiter has heat but it is not always warm because it doesn't always have direct sunlight from the Sun.
