## anonymous one year ago 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!!

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

3. anonymous

okay!! how can we plug in? :/

4. Michele_Laino

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

ohh okay! so we get 130? and that is the same as gold? so our answer is gold? :O

6. Michele_Laino

yes!

yay! thank you:D
