Answer:
Molecular solids
Covalent compounds
Explanation:

Endothermic bc of the temperature change
Answer:
The sample will look expanded and occupy more space.
Explanation:
Since, the pressure is constant here, but the temperature is changed. Therefore, according to Charles' Law Volume is directly proportional to Temperature, provided the pressure is kept constant. Mathematically:
V1/T1 = V2/T2
V1 = (T1/T2)(V2)
V1 = (300 k/450 k)(V2)
<u>V1 = (0.67)V2</u>
The equation indicates that The fina volume of the gas V2 will be greater than the initial volume V1. <u>Thus, sample will look expanded and occupy more space than the previous state.</u>
none of the above. is the answer
