In the gaseous state, the molecules are spread very widely apart from one another and are free to move about. If placed in a container, the molecules will occupy the volume of the container and take its shape as well.
The molecules in the liquid state are closer than in the gaseous state and less free to move about. They are in layers that slide over one another, allowing the substance to flow. If placed in a container, the liquid water will take its shape but not the volume.
The molecules in the solid state are fixed in position, only able to vibrate about their fixed points. The structure formed is rigid, it does not flow and its shape and volume are fixed.
Answer:
A, C, and D
Explanation:
The correct options that apply to the principal conservation of energy are A, C, and D.
A is correct because energy can neither be created nor destroyed. However, energy can be transfered from one location to another or be converted from one form to another. <em>Whether transferred to converted, the magnitude remains the same.</em>
C is correct because energy cannot be destroyed but can be transferred or converted. <em>Hence, if a body or a location loses temprature, then the loss is being gained by another body or location.</em>
D is also correct. A closed system is a system that does not exchange matter with its surroundings. <em>Hence, the total energy remains the same within the system. </em>
D. Matter and energy are the same.
The rate of growth is faster in the (10 - 14) age group and slows down after the age of 14. After the age of 16 the growth is the slowest
