The volume of the drum after chilled quickly is 3.6 L.
<u>Explanation:</u>
As per the Charles Law, for any gas at constant pressure, volume of the gas is in direct proportion with the temperature measured in Kelvin. As the temperature increases, the gas expands and vice versa.
After chilling the drum, the volume will get reduced and it can be found as,
V2 =
=
= 3.6 L
Here the drum is chilled quickly, that is temperature is reduced and so the volume also decreases.
I think the correct answer would be the first option. Scientists need scientific models because they can often be used to make predictions. Models are representation of a process, natural phenomenon, or an idea that is being used to describe and define the occurrence which cannot be seen directly. These are very useful tools in order to predict certain values that would be tedious to be obtain through experiment. Also, this would help scientists to obtain values that is outside the range of their experiment. Examples of these models are the models of the motions of the earth, sun and the moon.<span />
Answer:
No it is a poor conductor of heat but is a fair conductor of electricity
Explanation:
Answer:
Explanation:
Relation of with is given by the formula:
where,
= equilibrium constant in terms of partial pressure
= equilibrium constant in terms of concentration
R = Gas constant
T = temperature
= change in number of moles of gas particles =
when = 0
a)
= change in number of moles of gas particles =
b)
= change in number of moles of gas particles =
c)
= change in number of moles of gas particles =
d)
= change in number of moles of gas particles =
Thus for reaction , , as = 0
Answer: (2), increases
Explanation: Metals are substances which readily loose electrons.
