Chapter 5: Problem 18

A coin and a piece of glass are both heated to \(60^{\circ} \mathrm{C}\). Which will feel warmer when you touch it?

Short Answer

Expert verified
Answer: The coin will likely feel warmer when touched compared to the piece of glass, due to its higher thermal conductivity.

Step by step solution

01

Define thermal conductivity

Thermal conductivity is a property of a material that measures its ability to conduct heat. In this context, the object that has higher thermal conductivity will feel warmer when touching it, as it can transfer heat more efficiently to the hand.
02

Compare thermal conductivity values for given materials

In general, metals have higher thermal conductivity than non-metals; therefore, the coin (assuming it's made of metal) has higher thermal conductivity than the glass. We need to compare the thermal conductivity values for the two materials to confirm our assumption.
03

Check the comparative sensation

We can expect the object with higher thermal conductivity to feel warmer when touching it. Since the coin is made of metal and metals generally have higher thermal conductivity than non-metals like glass, the coin will likely feel warmer when touched.
04

Conclusion

Based on the comparison of thermal conductivity values, the coin will likely feel warmer when touched compared to the piece of glass, even though both have been heated to the same temperature of \(60^{\circ} \mathrm{C}\).

What is the significance of absolute zero?

In Example \(5.3\), is it really necessary to know the mass of the concrete block to solve this problem? Put another way, would the answer be different if it was a 10 -kg block that was dropped instead of a 5 -kg one?

What is entropy? In general, how does the entropy of a system change with time?

What happens to the atoms and molecules in a substance as its temperature increases?

A company decides to make a novelty glass thermometer that uses water instead of mercury or alcohol. (a) The thermometer would include a warning informing the user that it should not be exposed to temperatures below \(0^{\circ} \mathrm{C}\). Why? (b) Suppose the thermometer is taken outside where the temperature is \(1^{\circ} \mathrm{C}\). Describe how the level of the water would change as it adjusts to the new temperature and how at some point it would behave very differently than a mercury- or alcohol-filled thermometer.
