A blacksmith strikes a piece of metal with a hammer repeatedly. The metal slowly begins to glow as the temperature increases, and the metal becomes more malleable. Which changes on a microscopic level led to the visible changes in the properties of the metal?

Question

The average temperature of the particles increased

The potential energy of the particles decreased

The kinetic energy of the particles decreased

The average speed of the particles increased

Answer 1

I did it for the boys the answers are

1. Temperature
2.The average speed of the particles increased
3.Heat flows from hot to cold and is the transfer of thermal energy
4.The molecules will have more potential energy because of their arrangement

Answer 2

nic is right

Answer 3

Thanks nic

Answer 4

the third is not correct

Answer 5

The 3rd question answer is 'Heat flows from hot to cold and is the transfer of thermal energy.' I chose 'Heat flows from cold to hot and is the transfer of thermal energy.' by mistake so make sure you read what you've chosen just to make sure you have it right. But yes, Nic is right on all of the questions, thank you!

Answer 6

Yes thanks nic your 100% correct I got 4/4 Anwsers are below!

1) Temperature
2) The average speed of the particles increased.
3) Heat flows from hot to cold and is the transfer of thermal energy.
4) The molecules will have more potential energy because of their freedom to move

Answer 7

I love this website

Answer 8

123 is correct for Nic, but the 4th question I got wrong, it is the total kinetic energy of all particles in a substance.

Answer 9

first i swerv my top a then i finish the lyrics
