1. A student wants to cool 0.25kg of diet soda (mostly water), initially at 25°C, by adding ice initially at -20 °C. How much ice should she add so that the final temperature will be 0 °C with all the ice melted if the heat capacity of the container maybe neglected? Cwater = 4, 186 J/kg-Cº Answer: Cice=2.09 x 103³ J/kg-Cº L₁= 3.35 x105 J/kg mice = 0.069 kg (69 g)

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.
