Answer:
yes, in certain cases
there are different types of bondings between atoms
and in some they lend electrons to make their atom stable this type of bonding is called ionic bonding
and in covalent bond the atoms share their electrons
 
        
             
        
        
        
According to Charles' Law the volume of an ideal gas is directly proportional to its absolute temperature in Kelvin keeping the pressure constant.
V∝ T, P  is constant  
where V, T and P are volume, temperature and pressure 
 =
 = 
where V₁, T₁, V₂ and T₂ are initial volume, initial temperature, final volume and final temperature.

Answer:
Rock A because after physical weather and chemical weathering it more likely for Rock A to experience more chemical weathering.
Explanation: Weathering: This is a geological term used to describe the various processes and Activities involved in the breaking down of rocks either through physical,mechanical,chemical etc actions into smaller particles. 
ROCK A WILL HAVE MORE CHEMICAL WEATHERING BECAUSE THE PHYSICAL WEATHERING MUST HAVE BROKEN DOWN THE PARTICLES FOR EASY WATER AND OTHER SUBSTANCE NEEDED FOR EASIER CHEMICAL REACTION OR WEATHERING.
