Answer:
Moles = Molecules / (6.0221415 x 10^23)
Explanation:
Answer:
The volume of a gas approaches zero as the temperature approaches absolute zero.
Step-by-step explanation:
You may have done a <em>Charles' Law experiment</em> in the lab, in which you measured the volumes of a gas at various temperatures.
You plotted them on a graph, and perhaps you were asked to extrapolate the graph to lower temperatures.
Your graph probably looked something like the one below.
There is clearly an x-intercept at some low temperature.
Inference: The volume of a gas approaches zero as the temperature approaches absolute zero.
Most solids a) are dense and difficult to compress.
Most solids are closely compacted, their molecules are close together and vibrate. They don't move freely like gas or water molecules do.
They are difficult to be squeezed or flattened.
