Dan got into his car in the middle of summer. When he sat on the hot black leather seats, he burned his legs. His sister said th

at conduction was the reason Dan burned his legs, but Dan blamed the sunshine and said it was radiation that caused him to get burned. Who was right and why?
Question 24 options:


Both Dan and his sister are right. The sun heated the car seats through radiation heat transfer, but then Dan touched the seat and the heat was conducted to his legs.


Dan was right because the sun heated the car without touching it. That is radiation.


Dan's sister was right because conduction can transfer heat through both solids and fluids (such as air).


Dan's sister was correct because Dan's legs touched the car seats. That is an indicator of heat transfer by conduction.

<h2>Answer:</h2>

The correct answer is option D is correct one which is, "Dan's sister was correct because Dan's legs touched the car seats. That is an indicator of heat transfer by conduction".

<h3>Explanation:</h3>

Conduction is the method of heat energy transfer in which the microscopic vibrations are the cause of heat transfer from one en of the material to another.

The argument was on the burning of Dan's leg not the heating of car.

So in this manner only conduction responsible for the Dan's leg burning.

As Dan sat in the car, his leg touched the seat, heat energy transferred from seat to leg through conduction.

The correct answer is D) Dan's sister was correct because Dan's legs touched the car seats. That is an indicator of heat transfer by conduction.

Conduction only happens when a heated object touches a non-heated (or not as heated) object. Radiation did cause the car to become hot, but conduction caused Dan to get burned.

Hope this helps!! :D

How does convection occur in the troposhere ​
adell [148]

Answer:The surface heated air expands as it warms, becomes less dense than surrounding cooler air and rises as buoyant and turbulent bubbles. This is convection and is the main process by which the troposphere mixes and heats. Although convection stirs and mixes the troposphere, the higher it is the colder it becomes.

9. What are the advantages of using an indicator to inform pH measurements? What are the advantages of using a pH meter?
Llana [10]

Answer:

The advantages of using an indicator to inform pH measurements:

It gives a mathematically result of the pH, in addition, it gives the precise pH of solvent, and it also gives an idea of the straight of the solution also.

Now, the advantage of using a pH meter:

It is a rapid method to characterize between acids, bases. However, this method does not show how strong acid or base actually are, plus it tends to gives a range of acidity or basicity not quite accurate as a result.
