Question

A 0.80 kg block of a substance requires 2.08 kJ of heat to raise its temperature 20 K. Use the table to identify the substance. (attached inside!)

Iron, aluminum, gold, or copper?

**not sure which it would be? :/ thank you!!

Answer 1

here we have to compute the specific heat, first, so we have to apply this formula:
\[\Large c = \frac{Q}{{m\Delta T}}\]

Answer 2

okay!! how can we plug in? :/

Answer 3

\[\Large c = \frac{Q}{{m\Delta T}} = \frac{{2080}}{{0.80 \times 20}} = ...\frac{{Joules}}{{Kg \times Kelvin}}\]

Answer 4

ohh okay! so we get 130?

and that is the same as gold? so our answer is gold? :O

Answer 5

yes!

Answer 6

yay! thank you:D

Answer 7

thank you!! :D
