I tried to answer this below but coin was misspelled
coin has higher heat transfer, will het your finger up faster. "
I want a clear answer please?
To determine which object will feel warmer when you touch it, we need to consider their thermal conductivity. Thermal conductivity is the ability of a material to conduct heat. In this case, we can compare the thermal conductivity of a coin and glass.
Generally, metals, including coins, have high thermal conductivity, meaning they are efficient at conducting heat away from your skin. Glass, on the other hand, has relatively low thermal conductivity, which means it is not as efficient at conducting heat.
Considering this, when you touch the coin and piece of glass heated to the same temperature, the coin will feel much colder than the glass. This is because the coin will conduct heat away from your skin more rapidly, making it feel cooler, while the glass will conduct heat more slowly, making it feel warmer.
However, it's important to note that the perceived warmth or coolness of an object also depends on factors like its texture, the duration of contact, and individual sensitivity.
