A. Natural Gas is a substance that is a source of hydrocarbons.
Answer:
Explanation:
The change in enthalpy of a substance when heated is given by
ΔH = m x Csp x ΔT
so the enthalpy change is dependent on the specific heat , i.e its capactity to absorb heat, and is not influenced by factors such as being closer to the melting point, volume , potential energy or being a solid or liquid.
The liquid is blue is an example of qualitative data. Qualitative data is data that can not be represented by numbers. The volume and density are both quantitative data.
