37. The coefficient of volumetric expansion for gold is 4.20 x 10-5/C. The density of gold is 19 300 kg/m³ at 0.0 °C. What is the density of gold at 1050 °C? A) 20 200 kg/ m3 B) 19 300 kg/m C) 19 000 kg/m³ Dj 18 800 kg/m3 E) 18 500 kg/m3 38.A block that slides on a rough surface slows down and eventually stops. The reverse process never occurs. That is, a block at rest never begins to move and accelerate on a rough surface without the action of an external agent. The second situation is forbidden because it would violate A) conservation of total energy. B) conservation of momentum. C) the first law of thermodynamics
