Worked Solution & Example Answer:The foil and the towel were both at a temperature of 10 °C - Junior Cycle Science - Question e - 2013
Step 1
Why did the foil feel colder?
Answer
The aluminum foil feels colder than the cotton towel because it is a better conductor of heat. When you touch the foil, it conducts heat away from your skin more efficiently than the cotton towel, which acts as an insulator.
Aluminum has a high thermal conductivity, meaning it can transfer heat quickly. As your skin warms the foil, it rapidly draws heat away, making it feel colder. Conversely, the cotton towel is a poor conductor of heat, which helps retain warmth and feels warmer to the touch.
