(Answer to Q. 1)  ANS: C
Boyle's law can be expressed as a ratio: P1V1 = P2V2.

(Answer to Q. 2)  ANS: A

(Answer to Q. 3)  ANS: C
Boyle's law states that at a constant temperature, the volume of a gas varies inversely proportion-al to pressure V = 1/P. The relationship between volume and temperature is expressed in Charles' law. The relationship between pressure and temperature is described by Gay-Lussac's law.

(Answer to Q. 4)  ANS: C
The relationship between pressure and volume is described by Boyle's law; between volume and temperature, by Charles' law; between pressure and temperature, by Gay-Lussac's law. Newton detailed the many relationships of gravitational force and motion.

(Answer to Q. 5)  ANS: D
Near the surface of the Earth, two equations apply: d = m/v, dw = w/v. In space and at zero gravity, weight is not a factor; at the Earth's core, extreme gravitational forces would increase the weight as mass remained constant.
