Some gas is trapped in a large syringe by a piston. The atmospheric pressure is 100kpa. The pressure gauge indicates that the gas pressurr is 200kpa above atmospheric pressure. The piston moves outwards and the volume of the gas doubles. The temperature remains constant. What is the new gas pressure?

The new gas pressure is 150 kPa.

Explanation :

Boyle's Law: This law states that pressure is inversely proportional to the volume of the gas at constant temperature and number of moles.

    (At constant temperature and number of moles)

where,

= initial pressure of gas  = (100+200) kPa = 300 kPa

= final pressure of gas  = ?

= initial volume of gas  = v

= final volume of gas  = 2v

Therefore, the new gas pressure is 150 kPa.

jupiter is the largest planet in our solar system, having a mass and radius that are respectively, 318 and 11.2 times that of earth. suppose that an object falls from rest near the surface of each planet and that the acceleration due to gravity remains constant during the fall. each object falls the same distance before striking the ground. determine the ratio of the time of fall on jupiter to that on earth.

its a 5.5 n

glad that
