why did a portion of the tabletop get cold when Natasha placed her cold drink on the table.
a.the table's molecules were vibrating more slowly in that area
b.the table's have spread farther apart in that area
c.the table's had gained energy in that area
d.(this is blank because there won't be that area if this answer was true)
i am studying for a test i have later today and would love some help
can u post them plz because im stuggling :(
its A i know trust me i did the test before and kept the answers
When Natasha placed her cold drink on the table, a portion of the tabletop got cold. This happens because of the process of heat transfer. Heat always flows from areas of higher temperature to areas of lower temperature, until the temperatures are equalized.
In this scenario, the cold drink has a lower temperature than the table. When they come into contact, heat transfer occurs. The answer to your question would be:
a. The table's molecules were vibrating more slowly in that area.
When the cold drink is placed on the table, the molecules in that specific area of the table absorb some of the heat energy from the drink. As a result, the molecules in that area of the table slow down their vibration, causing the temperature to decrease and making that portion of the tabletop feel cold.
I'd be happy to help! To understand why a portion of the tabletop gets cold when Natasha placed her cold drink on the table, we need to consider the concept of heat transfer. Heat is transferred from a warmer object to a colder object until both reach the same temperature.
In this case, when Natasha places her cold drink on the table, heat will begin to transfer from the table to the drink, aiming to equalize their temperatures. However, to determine which option explains this phenomenon, let's evaluate each option:
a. The table's molecules vibrating more slowly in that area: This option doesn't explain why the tabletop gets cold. Slower molecular vibrations would imply a decrease in temperature, resulting in a colder overall table, not just a portion of it.
b. The table's molecules have spread farther apart in that area: This option is incorrect. The spacing between molecules in a solid, such as a table, does not change significantly when a cold drink is placed on it.
c. The table's molecules have gained energy in that area: This option is incorrect. Gaining energy would result in an increase in temperature, which is opposite to what actually happens.
d. This answer doesn't contribute to the explanation.
Based on the analysis, the correct answer is option a. The portion of the tabletop gets cold because the table's molecules are vibrating more slowly in that area. When the drink absorbs heat from the table, it causes the nearby molecules to lose energy and slow down their motion, resulting in a colder sensation on the tabletop.
Understanding the underlying principles and reasoning behind concepts is essential for success in your test. Good luck with your studies and your upcoming test!
