Question

On a hot day, the beach sand gets hot but the water stays cool. Would you predict that the specific heat of sand is higher or lower than that of water? Explain.

Accepted Answer

Welcome back everyone. Even when exposed to the same hot weather condition, a deck made of rubber tiles feels hotter than a duck made of concrete tiles. Based on this observation predict whether it's a specific heat of rubber is higher or lower than that of concrete and provide a justification for your answer. In choice. A it states that the heat of rubber is lower than the specific heat of concrete since it requires less heat to raise its temperature compared to concrete. In choice B it states that the specific heat of rubber is lower than concrete because it requires more heat to raise its temperature compared to concrete. And in choice C it states that the specific heat of rubber is the same as that of concrete. Since they both require the same amount of heat to raise their temperature. We're going to need to recall our concept of C which represents our specific heat capacity of a substance and recall that specific he capacity describes our amount of heat that is required to change one g of a substance by one degree Celsius. Now going back to the prompt, we're told that we or the tiles whether rubber or concrete experience the same hot weather conditions recall that heat can be expressed by the term Q. So for our rubber and concrete tile, we have the same cue that is applied. Now noting down what we're given from our pumps, we are given the fact that our temperature change of our rubber is greater than that of the temperature change of our concrete tiles. So the concrete tiles have to absorb more heat before they reach a higher temperature in comparison to the rubber tiles which reach the higher temperature fairly quickly. So we can conclude that our rubber tiles require less heat to increase its temperature. And so therefore, our specific heat of our rubber would be lower than the specific heat capacity of our concrete tiles. So going back to our answer choices, we can rule out choice C which states that the specific heat of the tiles would be the same. And we can also rule out the specific uh choice C sorry choice B since it states that the rubber tiles require more heat to raise its temperature compared to concrete when we agreed that it requires less heat to increase its temperature compared to the concrete. So that leaves us with choice. A as our only correct choice, which explains that for our observation of the rubber tiles feeling hotter than that of concrete when exposed to the same heat conditions, our specific heat of rubber is going to be lower than the specific heat of concrete since it will require less heat to raise its temperature compared to the concrete. So a is our final answer. I hope that this made sense and let us know if you have any questions.
