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

Answer:

Matter is anything that has mass and takes up space. Matter can change form through physical and chemical changes, but through any of these changes, matter is conserved. The same amount of matter exists before and after the change none is created or destroyed.

In bullet points: explain the difference between thermal energy, heat and temperature.
sergeinik [125]
  • Thermal Energy- is the energy that comes from heat. This heat is generated by the movement of tiny particles within an object. The faster these particles move, the more heat is generated.

  • Heat-energy is the result of the movement of tiny particles called atoms, molecules or ions in solids, liquids and gases. Heat energy can be transferred from one object to another. The transfer or flow due to the difference in temperature between the two objects.

  • Temperature- is a measure of how hot or cold something is; specifically, a measure of the average kinetic energy of the particles in an object, which is a type of energy associated with motion.
