When the barometer rises it means air pressure goes up. When that happens there is clear skies and little clouds. So you would be expecting hotter weather.
Answer:
Density = 0.17 g/L
Explanation:
It is given that,
Volume of the inflated balloon filled with Helium,
Mass, m = 374 g
We need to find the density of helium. It is equal to its mass per unit volume. It can be given by :
d =m/V
So, the density of helium in the balloon is 0.17 g/L.
Gas 2 because it has more particles that are colliding
