Q6. Dealing with two different samples in a thermodynamic experiment, a 1.55 kg sample increases its temperature from 14.5°C to 49.2°C by absorbing 40 kJ of heat energy and second one absorbed 50 kJ of heat energy to change its temperature from 15.8ºC to 50.5°C. Compare its specific heat capacities, if they have same mass. Point out which has more specific heat capacity? This sample taken in a closed vessel at 14.5°C under a pressure of 98 mm of Hg. How much pressure (in atm) is required to increase its temperature to 49.2 °C? can you express this result in bar?

Expert Solution
Step 1
Here we look into the relation between heat, temperature and heat capacity of material and use it to compare the heat capacities of given samples. Next, we use Charles law to determine the final pressure.
