1. A block of aluminum weighing 140.0 g is cooled from 98.4° C to 62.2° C with the release of 1080 cal of heat. From these data, calculate the specific heat of aluminum.
2. A total of 54.0 cal of heat are absorbed as 58.3 g of lead is heated from 12.0° C to 42.0° C. From these data, what is the specific heat of lead?
3. A 25.0 g block of rhenium metal (specific heat = 0.0329 cal/ g° C) is heated from 25.0° C to 88.2° C. How much energy is required to heat the block of rhenium?
4. A sample of mercury metal is heated from 25.5° C to 52.5° C. It took 187 cal of heat to make this temperature change. What mass of mercury was in the sample? The specific heat of mercury is 0.033 cal/ g° C
5. The specific heat of ethanol is 2.46 J/g oC. Find the heat required to raise the temperature of 193 g of ethanol from 19oC to 35oC.
None I don't believe.
