Question

You heat the end of three metal rods and measure the temperature at the other ends of the rods. Which result shows the best thermal conductivity? A. the rod that changes temperature last B. the rod that shows no change in temperature C. the rod that shows the first increase in temperature D. the rod that shows the first decrease in temperature

Answer 1

the rod that shows the first increase in temperature

Explanation:

The rod that shows the first increase in temperature is that which has the best thermal conductivity. Thermal conductivity is the ability of a substance to conduct heat.

• Most metals have a high thermal conductivity which results from the transfer of heat due to the fixed vibration of their atoms.
• Substances that conducts heat faster will increase in temperature progressively well are good thermal conducts.
• This shows the relative ease with which their component atoms are able to vibrate and transfer heat.
