Answer:
When an electron is hit by a photon of light, it absorbs the quanta of energy the photon was carrying and moves to a higher energy state. One way of thinking about this higher energy state is to imagine that the electron is now moving faster, (it has just been "hit" by a rapidly moving photon).

Answer:
Robert Boyle
Explanation:
Robert Boyle was an Irish chemist and is famously referred to as the first modern chemist. He was born on the 25th of January, 1627 in Lismore, Ireland and died on the 31st, December 1691, London, United Kingdom.
Robert Boyle was the first to determine the relationship between the pressure and volume of a gas.
Boyles states that when the temperature of an ideal gas is kept constant, the pressure of the gas is inversely proportional to the volume occupied by the gas. 
Mathematically, Boyles law is given by;
 
 
 
 
Where;
V1 and V2 represents the initial and final volumes respectively.
T1 and T2 represents the initial and final temperatures respectively.
 
        
             
        
        
        
Answer:the branch of science which examines the material of the universe and changes that these materials undergo
Chemistry deals with composition,structure,properties of matter and changes that these materials undergo
 
        
             
        
        
        
Yes because of the gas combination.
