## anonymous one year ago The amount of heat needed to raise 2.0 kg of a substance by 80 K is 33 kJ. What is the specific heat of the substance? A. 210 (J/kg*K) B. 2,100 (J/kg*K) C. 1,300 (J/kg*K) D. 1.3 * 10^6 (J/kg*K)

it is simple, we have to apply this formula: $c = \frac{1}{m}\frac{{\Delta Q}}{{\Delta t}} = \frac{1}{2}\frac{{33 \times {{10}^3}}}{{80}}$

ok! so we get this? 206.25? so our solution should be choice A?

3. Michele_Laino
