Directions: Based on the activity, answer the following questions:
Q1. What did you feel upon touching both the spoons?
Q2. Which among the spoons is the best conductor of heat? Which spoon is the poorest
conductor of heat?
Q3. Did heat transfer takes place between your hands and the spoons? If yes, how and in
what direction did energy transfer between them?
Q4. What happened to the food coloring after placing the glass above the other glass?
Why did this happen?
Q5. How is heat transfer taking place in the setup?
Q6. You have just observed another method of heat transfer called convection. In your
own words, how does convection take place?
Q7. How is this process different from conduction?
Q8. Do you think convection only occurs when the source of heat is in the glass at the
bottom? What if the source of heat is in the glass at the top? Explain.
Note: You may try it by interchanging the containers in your previous experiment. Please be
careful with the hot water, seek the help of an adult if possible.

Answer!
Q1. the kinetic energy along by colliding with molecules in the adjacent, cooler part. This continues through the spoon, until the molecules in the handle are also heated.
Q2. Metal is a good conductor of heat, stainless steel is a poor conductor.
Q3. Yes, Heat moves naturally by any of three means. The processes are known as conduction, convection and radiation. Sometimes more than one may occur at the same time.
Q4. Molecules in a liquid have enough energy to move around and pass each other, because water can flow and take the shape of the glass you pour it into.
Q5. Convection currents are set up in the fluid because the hotter part of the fluid is not as dense as the cooler part.
Q6. with a lot of heat energy in a liquid or gas move and take the place of particles with less heat energy.
Q7. In conduction, heat transfer takes place between objects by direct contact. In convection, the heat transfer takes within the fluid.
Q8. that glass is such a valuable material is that it exhibits a very low absorption of electromagnetic radiation in the visible range.
Q9. (Own answer)
Q10. it can take place anywhere but the other modes , convention and conduction , cannot take place in vacuum but radiation can.
