When using a manometer to check boyle's law, why is the pressure changed slowly? a. to avoid compressing the liquid b. to avoid compressing the gas c. to avoid changing the gas temperature d. to avoid changing the mass of the gas

Option C is correct.

c. to avoid changing the gas temperature

Manometers are devices using columns of a suitable liquid to measure the difference in pressure between two points and the atmosphere. A manometer is required for measuring substantial gauge pressures. It is the modified form of the piezometric tube.

question: ray weighs 100 kilograms, his wrestling partner, bobby, weighs 50 kilograms. if ray moves at 4 m s , how fast will bobby have to run at him to apply an equal amount of kinetic energy?

answer: 8 m/s he needs to run twice as fast to keep up so he has some work to do

explanation:   if the mass has units of kilograms and the velocity of meters per second, the kinetic energy has units of kilograms-meters squared per second squared.
