Q3. (I) A certain car has 14.0 L of liquid coolant circulating at a temperature of 93°C through the engine's cooling system. Assume that, in this normal condition, the coolant completely fills the 3.5-L volume of the aluminum radiator and the 10.5-L internal cavities within the aluminum engine When a car overheats, the radiator, engine, and coolant expand and a small reservoir connected to the radiator catches any resultant coolant overflow. Estimate how much coolant overflows to the reservoir if...
(I) The Eiffel Tower (Fig. 13-31) is built of wrought iron approximately 300 m tall. Estimate how much its height changes between January (average temperature of 2°C) and July (average temperature of 25°C). Ignore the angles of the iron beams and treat the tower as a vertical beam. Ignore effects of Gravity (I) A concrete highway is built of slabs 12 m long (15°C). How wide should the expansion cracks between the slabs be (at 15°C) to prevent buckling if...
HELP PLEASE Most automobiles have a coolant reservoir to catch radiator fluid that may overflow when the engine is hot. A radiator is made of copper and is filled to its 21.5-L capacity when at 13.0degreeC. What volume of radiator fluid will overflow when the radiator and fluid reach their 95.0degree C operating temperature, given the fluid's volume coefficient of expansion is 400.10^-67degreeC and that of copper is 51 . 10_7degreeC. Note that most car radiators have operating temperatures of...
2) A person pours 400 g of water at 45°C into an 855-g aluminum container with an initial temperature of 10°c. The specific heat of aluminum is 900 J/(kg-K) and that of water is 4190 J/(kg K). What is the final temperature of assuming no heat is exchanged with the surroundings? A) 3 B) 35°C D) 28°C E) 33°C 3) A heat engine with aneffic ency of 300% performs 300 of work. How much heat is discharged to the lower...
