Question

Heat is applied to 1.0 kilogram of copper. The temperature of the Copper changes from -8

Answer 1

To 9 celcius. It takes 390 heat units to increase the temperature of 1 kilogram of copper 1 celcius. How many heat units were apples to the sample

Answer 2

Is this the full question? And is this for chem? Because I think you'd use the equation (mass(g))*(specific heat capacity of copper)*(change in temperature)?

Answer 3

Sadly this is 7th grade math.

Answer 4

the mass is the same so ignore for our purposes just to state equivalent
to change by 1 degree needs 390 units of heat
here changed from -8 to 9 degrees how any degrees changed ?

Answer 5

17. So would be 17*390?

Answer 6

many correct

Answer 7

Thx.

Answer 8

you are welcome

next time open a new question

need to have the same units then you can compare

Answer 11

how many sec make a minute?

Answer 12

Sorry i tried. New to this. So I did 900/1830 and 15/18

Answer 13
