An Introduction to Thermal Physics 1
Problem 35P According to the Sackur-Tetrode equation, the entropy of a monatomic ideal gas can become negative when its temperature (and hence its energy) is sufficiently low. Of course this is absurd, so the Sackur-Tetrode equation must be invalid at very low temperatures. Suppose you start with a s

Problem 3P Define Physical Property and chemical property. Identify each type of property in the following statements: (a) Yellow-green chlorine gas attack silvery sodium metal to form white crystal of sodium chloride(table salt). (b) A magnet separates a mixture of black iron shavings and white sand

Physics: Principles with Applications 6
The Achilles tendon is attached to the rear of the foot as shown in Fig. 9-66. When a person elevates himself just barely off the floor on the "ball of one foot." estimate the tensionFtin the Achilles tendon (pulling upward), and the (downward) forceFBexerted by the lower leg bone on the foot. Assume

Problem 32E On a horizontal, frictionless table, an open-topped 5.20-kg box is attached to an ideal horizontal spring having force constant 375 N/m. Inside the box is a 3.44-kg stone. The system is oscillating with an amplitude of 7.50 cm. When the box has reached its maximum speed, the stone is su
