Boyle's law states that in an ideal gas system, pressure and volume have an inverse relationship when the temperature remains constant. So B.
Answer:
Explanation:
Given that,
Orbital period, T = 42.5 hours = 153000 seconds
The average distance of Jupiter's mass, r = 422,000 km
We need to find Jupiter's mass. The formula for the orbital period is given by :
So, the mass of Jupiter is 
.
Answer:
1.....
2.....
Explanation:
1. For the elements in column 1,2 and 13-18 the atoms in the same column have the same amount of outermost electrons, called valence electrons. Atoms in column 1 (H, Li and Na for example) have 1 valence electron.
2. Electron affinity increases from left to right across the periodic table. This is caused by the decrease in atomic radius. As we already explained, moving from left to right across a period, atoms become smaller and smaller as the atomic number increases.
