Heat Capacity & Temperature ChangesStates of Matter: Solid, Liquid & GasFiltration ApparatusDistillation ApparatusExample 1An antacid tablet weighing 0.853 g reacted with an acid solution weighing 56.52 g.3 One of the reaction products was carbon dioxide gas which was observed as a fizz.3 If the resulting solution weighed 57.15 g, how many grams of carbon dioxide were produced?Answer: 0.22 gExample 2Convert 70.0°F to °C and to Kelvins.Example 3If it is 28°C outside, would you consider it a warm day or a cold day?Example 4Express absolute zero in units of °F, °C,and K.Example 5A brownie contains 320 Calories. Express this in calories and in Joules.Example 6How much energy is required to heat 10.0 gof iron from 25.0°C to 100.0°C? The specific heat capacity of iron is 0.45 J/g°C.Example 7A 19.6 g sample of an unknown metal washeated from 22.0°C to 53.8°C by the additionof 558.6 J of energy. Find the specific heat capacity of the metal. Refer to the table of specific heat capacities in your textbook to predict what metal this might be.Example 8How much energy (in joules) is needed to heat a cupof water for coffee? Assume the following:the cup holds 250 mL of water the density of water is 1.00 g/mL the water is initially at 19°C the ideal temperature for brewing coffee is 97°C Answer: 81.6 x 103
