A piston contains 1 kg of argon gas at 300 K and 1 bar. The initial Volume occupied by the gas is 0.624 m3. Heat, in the amount 104.2 KJ, is added to elevate the temperature of the argon to 500 K while the pressure in the piston remains constant. The final gas volume is 1.041 m3. i.) If the expansion is reversible, calculate work associated with the process and draw a P – V diagram which schematically shows this calculation. ii.) Is the value of work positive or negative ? why? iii.) Calculate the extensive value ?Ut. iv.) Calculate the extensive value ?Ht. v.) Calculate the intensive value ?H. vi.) Prove that for any reversible isobaric process, such as the one above, ?Ht = Q

Four horses are tethered at 4 corners of a square field of side 70 metres so that they just cannot reach one another. What is the area left ungrazed by the horses
At time t=0 a grinding wheel has an angular velocity of 26.0 rad/s. It has a constant angular acceleration of 29.0 rad/s^2 until a circuit breaker trips at time t = 2.50 s. From then on, the wheel turns during an angle of 440 rad as it coasts to a..
A shot putter launches a 7.240 kg shot by pushing it along a straight line of length 1.650 m and at an angle of 34.00° from the horizontal, accelerating the shot to the launch speed from its initial speed of 2.500 m/s (which is due to the athlete'..
