Question

Explain why dew forms on the metal parts than on the rubber parts of a bicycle placed out side at night.

Answer 1

Answer:

Dew is water in the form of droplets that appears on thin, exposed objects in the morning or evening due to condensation.

Explanation:

As the exposed surface cools by radiating its heat, atmospheric moisture condenses at a rate greater than that at which it can evaporate, resulting in the formation of water droplets.[2]

When temperatures are low enough, dew takes the form of ice; this form is called frost.

Because dew is related to the temperature of surfaces, in late summer it forms most easily on surfaces that are not warmed by conducted heat from deep ground, such as grass, leaves, railings, car roofs, and bridges.

Dew should not be confused with guttation, which is the process by which plants release excess water from the tips of their leaves.

Answer 2

Answer:

Dew is water that condenses into droplets and forms in the morning or evening on thin, exposed things.

Explanation:

• The creation of water droplets occurs as atmospheric moisture condenses at a rate greater than that at which it can evaporate as the exposed surface cools by radiating its heat.
• A specific volume of water vapour is present in the air.
• The amount of water it can hold greatly depends on the temperature outside.
• The amount of water vapour that air can retain increases with temperature.
• Numerous items outside, such as grass, cars, many metal objects, lawn chairs, etc., are unable to powerfully transfer heat from deep in the earth or they otherwise release heat more quickly than they can absorb it in the evening and during the night.
• These items' surfaces may eventually become colder than the "dew point" As a result, droplets of water will form on the items due to the condensation of air moisture.

Therefore, dew forms on the metal parts rather than the rubber parts.
