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.

ANSWER THE FF AND SHOW THE COMPLETE SOLUTION: a.) A Styrofoam cooler contains ice at 0 degrees Celsius. For the ice to melt into water at 0 degrees Celsius, it needs to take in 34 kJ of heat. How long would this take if the heat current through the cooler is 9.4 W? (answer for this is: 1hr) b.) A Styrofoam cooler contains ice at 0 degrees Celsius. The cooler is left outside where the temperature is 30 degrees Celsius. For the ice to melt into water at 0 degrees Celsius, it needs to take in 34 kJ of heat.
