10. Concrete sidewalks are always laid in sections, with gaps between each section. For example, the figure shows five identical 5.70-m sections, the outer two of which are against immovable walls. The four identical gaps between the sections are provided so that thermal expansion will not create the thermal stress that could lead to cracks. What is the minimum gap width necessary to account for an increase in temperature of 38 °C? cm Gap il6 ccil6 ccil6 cci16. 116 cci16 cci16 ceil6 ceil6 ccil6 ce écile 6 cc 16 ceil6 cci16 ceit 116 cci16 ceicci16 cci16 cci16 ceil ceil6 ccil6 ccil6 cei16

14. 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 12-L capacity when at 10°C. What volume of radiator fluid will overflow when the radiator fluid reach their 95°C operating temperature, given that the fluids volume coefficient of expansion is B= 400X10^-6/°C? Note that this coefficient is approximate, because most car radiators have operating temperatures of greater than 95° C. The volume coefficient of expansion of copper is 5.1X10^-5 /°C. Hint:consider the expansions of both the fluid and the radiator.
