Question
Find the specific heat of the unknown in J/kg .o C using Table 2 below to help. Note that your mass measurements were in grams
Find the specific heat of the unknown in J/kg.oC using Table 2 below to help. Note that your mass measurements were in grams and not kilograms, so you will have to change your final answer to reflect kilograms.
| Variable | Observation |
| Mass of cup in grams | 31.2 |
| Mass of cup and water in grams | 171.1 |
| Mass of unknown material in grams | 181 |
| Initial temperature of the unknown material in oC. | 100 |
| Initial temperature of the water in oC. | 12 |
| Final temperature of the unknown material and the water in oC. | 28.5 |
Show your calculation/work for the mass of water:
Show your calculation/work for the DT for water.
Show your calculation/work the heat gained by the water.
Show your calculation/work for the DT for the unknown.
Show you calculation/work for the specific heat of the unknown in J/g,oC
100c*4.184*171.1= 71588.2
| Variable | Calculation Result |
| Mass of water in g | |
| Specific heat of water J/g,oC | 4.186 |
| DT for water (Tf - Ti) | |
| Heat Gained by the Water in J | |
| Heat Lost by the Metal in J | |
| Mass of unknown in g | |
| DT for unknown | |
| Specific heat of unknown J/g,oC | |
| Specific heat of unknown J/kg,oC |
