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.
Answer:
C. Between 0 and 1 seconds
Explanation:
Since 0 - 1 seconds the car accelerates to 20mph. The rest each second the car accelerates 5mph.
Answer: d) 16.34 grams
Explanation:
To calculate the moles :
According to stoichiometry :
As 2 moles of 
are produced by= 4 moles of 
Thus 0.292 moles of are produced by= =
of
Mass of 
Thus 16.34 g of will be needed
Well, from what i remeber, u need a charge at each end of the wire, then u turn it on by a generator, and the elecricity thats in the charges, or batteries, travels up the wires.
hope this helps.
impulse= force ×time
1) 0.1×200=20
2) 5×5.5=27.5
3) 10×2=20
4) 25×0.8==20
so the answers are 1,3,4
<h3>hope it helped :-)</h3>
