Question

Give an example of an energy transformation.
@hilbertboy96 @DanJS @eric_d

Answer 1

think of ball at the top of hill not moving at first. What kind of energy does it have?

Answer 2

The burning of a log.

Answer 3

a steam turbine

Answer 4

can you explain the burning of a log

Answer 5

a pendulum

Answer 6

Chemical energy to heat energy/kinetic enrgy of the molecules

Answer 7

the burning of a log is potential energy from the log becoming thermal energy as the fire burns

Answer 8

i get it thanks guys! you guys are very helpful and understanding! :)

Answer 9

Give an example of heat transfer by convection.

Answer 10

an oven

Answer 11

microwave as well if i am correct

Answer 12

microwave is radiation

Answer 13

yea my bad lol

Answer 14

Convection currents in the ocean, warm water flows towards colder waters

Answer 15

is that an example?

Answer 16

yeh

Answer 17

and it explains everything too?

Answer 18

can you explain it a little better @ danJS

Answer 19

@DanJS

Answer 20

Convection is like the diffusion of heat

Answer 21

The hot water diffuses into the colder water , warming it up

Answer 22

how can i put that in an answer?

Answer 23

like give e a complete example

Answer 24

@DanJS

Answer 25

Convection is the movement of heat energy from one place to another by the movement of fluids. Essentially it is a movement of heat by mass transfer. Convection is usually used to describe the effects of heat conduction within a fluid, also called diffusion.

Answer 26

That is what the ocean and the atmosphere do

Answer 27

ok now can you give me an example of heat transfer by convection and explain it please. It can be any example. Thank you so much! :) @DanJS

Answer 28

that is what i just said

Answer 29

whats the example though?

Answer 30

the flow of heat in the oceans and the atmosphere, because of the paragraph above.

Answer 31

oh ok :)

Answer 32

thank you soooo much! you helped me a lot :)

Answer 33

or

Answer 34

thermal convection from a human hand to the surrounding still atmosphere. Like in those thermal imaging cameras you can see the color change where heat is moving

Answer 35

Or those ripples in the atmosphere close to a hot pavement road, that is from convection currents distorting the light
