1. A gas has an initial volume of 2.0 m3 is heated with isobaris condition until finally the volume to 4.5 m3. If the gas pressure is 2 atm, determine the gas outside!(1 atm = 1.01 x 105 Pa)2. 1.5 m3 of helium gas is heated isobaric temperature 27oC to 87oC. If the gas pressure of 2 x 105 N/m2 helium, helium gas did venture outside for ....

1. 16 grams of Oxygen gas (M = 32 g / mol) is at a pressure of 1 atm and a temperature of 27oC. Determine the volume of gas if:a) given the value of R = 8.314 J / mol.Kb) given the value of R = 8314 J / kmol.K2. Mass of 4 kg gas temperature is 27oC in a hollow tube.

If the tube is heated to a temperature of 127oC, and expansion tubes ignored specify:a) the mass of gas remaining in the tubeb) the mass of gas that comes out of the tubec) ratio of the mass of the gas that comes out of the tube with the initial mass of gasd) mass ratio of gas remaining in the tube with the initial mass of gase) ratio of the mass of the gas that comes out of the tube with a mass of gas remaining in the tube

1. A fish is at a depth of 15 meters below the water surface.

If the water density 1000 kg/m3, 10 m/s2 acceleration of gravity and air pressure outside of 105 N / m, determine:a) hydrostatic pressure experienced by fishb) total pressure experienced by fish2. A child would take up rock-mass 1 ton with tool as shown below!

If the cross-sectional area of the pipe is the pipe cross-sectional area 250 times smaller and negligible pressure fluid filler pipe, determine the minimum force that must be given so that the child can be lifted rocks!

1. A bucket and its contents with mass m = 20 kg are connected by a rope to a solid cylindrical pulley of mass M = 10 kg. Bucket initially detained and then released in a silent condition.

If the pulley radius 25 cm and 10 m/s2 acceleration of gravity specify:a) the acceleration of falling objects motion mb) the angular acceleration of the pulleyc) string tension2. A child climbing a rope and stops at the position as shown in the following picture!

Determine the magnitude of the voltage-tension strap that secures the child if the child's mass is 50 kg!

Ahmad fill the bucket that has a capacity of 20 liters with water from a faucet like the picture below!

If the cross-sectional area faucet with diameter D2 is 2 cm2 and velocity of water flow at the faucet is 10 m / s find:a) Water dischargeb) The time it takes to fill the bucket
