Alkali metals, alkali earth metals, transition metals, noble gases, halogens, and chalcogens
Answer:
See below
Explanation:
Q = m c T c = specific heat T = temp change Q = heat joules
32 = 4 c 40 <u> c = .2 J/g-C</u>
314 to 344 k is a change of 30 K
Q = m c T
= 4 * .2 * 30 = <u>24 Joules </u>
The answer is C because as you add heat, the atoms grow in energy. See the law of conservation of energy states that energy is neither created nor destroyed. This means energy is being added, or converted, in the form of adding heat, increasing the speed of the molecules. This also explains the change from state to state.
