Answer:
1. Inversely proportional 
2. Option C. Boyle's Law 
3. Directly proportional 
4. Option C. Gay-Lussac's Law 
5. Directly proportional 
6. Option C. Charles' Law
Explanation 
Boyle's law states that the volume of a fixed mass of gas is inversely proportional to the pressure provided temperature remains constant. Mathematically, 
V & 1/P
V = K/P
PV = K(constant) 
Charles' law states that the volume of a fixed mass of gas is directly proportional to it's absolute temperature, provided pressure remains constant. Mathematically, 
V & T 
V = KT
V / T = K(constant) 
Gay-Lussac's Law states that the pressure of a fixed mass of gas is directly proportional to it's absolute temperature, provided the volume remains constant. Mathematically 
P & T
P = KT
P/ T = K (constant)
