1) A concrete highway is built of slabs 16.0 m long (at 18 °C). How wide should the expansion cracks be (at 18 °C) between the slabs to prevent buckling if the annual extreme temperatures are -27 °C and 54 °C? (The coefficient of linear expansion of concrete is 1.20 x 10-5 °C^-1)

2) A quartz sphere is 14.0 cm in diameter. What will be its change in volume if its temperature is increased by 320 °F? (the coefficient of volume expansion of quartz is 1.50 x 10^-6 °C^-1)

3) A small immersion heater is rated at 360 Watts. Estimate how long it will take to heat a cup of soup (assume this is 230g of water) from 21 °C to 52 °C.
