- Most automobiles have a coolant reservoir to catch radiator fluid than may overflow when 1he engine is hot. A radiator is made of copper and is filled to its 16.0L capacity when at 10.0C. What volume of radiator fluid will overflow when the radiator and fluid reach their 95.0C operating temperature, given that the fluid’s volume coefficient of expansion is =400106/C ? Note that this coefficient is approximate, because most car radiators have operating temperatures of greater than 95.0C.(9) A metal rod made of some alloy is to be used as a thermometer. At OoC its length is 40000cm, and at 1000C its length is 40060cm. (a) What is the linear expansion coefficient of the alloy? (b) what is the temperature when its length is 39975cm?On the sea bottom at the Galapagos Rift, water heated to 350 °C gushes out of hydrothermal vents at a depth of 3000 m. Will this water boil or remain liquid at this depth? Assume the enthalpy of vaporization for water to be independent of pressure and temperature.
