Explain. 3. Which is the consequence of copper's relatively low specific heat (0.385 J/(g°C)) compared to water (4.18 J/(g°C)) on the temperature change...
When 702.5 J of heat energy is added to a 53.0 g sample of solid copper, the temperature increases to 87.6°C. What was the original temperature of the solid in °C? The specific heat capacity of solid copper is 0.385 J/g • K.
A sample of copper absorbs 43.6 kJ of heat, resulting in a temperature rise of 75.0 °C, determine the mass (in kg) of the copper sample if the specific heat capacity of copper is 0.385 J/g°C.
have united attempts/There is no attempt penalty Question (6 points) See page 236 1st attempt See Periodic Table See Hint An insulated container is used to hold 48.5 g of water at 39.8°C. A sample of copper weighing 7.60 g is placed in a dry test tube and heated for 30 minutes in a boiling water bath at 100.0°C. The heated test tube is carefully removed from the water bath with laboratory tongs and inclined so that the copper slides...
It specific heat of copper is 0.385 J/(g.C). If 34.2 g of copper, initially at 24.0 C, absorbs 4.689 kJ, what will be the final temperature of the copper?
1st attempt See Periodic Table See Hint COAST Tutorial Problem Phthalates used as plasticizers in rubber and plastic products are believed to act as hormone mimics in humans. The value of AH comb for dimethylphthalate (C10H1004) is -4685 kJ/mol. Assume 0.870 g of dimethylphthalate is combusted in a calorimeter whose heat capacity (Ccalorimeter) is 6.35 kJ/°C at 21.5°C. What is the final temperature of the calorimeter? "С SUBMIT ANSWER 1 OF 5 QUESTIONS COMPLETED < 04/05 >
