Concept explainers
(a)
Interpretation:
The heat capacity of liquid toluene at 40°C should be calculated.
Concept introduction:
The amount of heat required to increase the temperature of the system by one degree is known as heat capacity. The unit to express the heat capacity is thermal energy per degree temperature.
(b)
Interpretation:
The heat capacity of toluene vapor at 40° C should be calculated.
Concept introduction:
The amount of heat required to increase the temperature of the system by one degree is known as heat capacity. The unit to express the heat capacity is thermal energy per degree temperature.
(c)
Interpretation:
The heat capacity of solid carbon at 40°C should be calculated.
Concept introduction:
The amount of heat required to increase the temperature of the system by one degree is known as heat capacity. The unit to express the heat capacity is thermal energy per degree temperature.
(d)
Interpretation:
The change in enthalpy for toluene should be calculated.
Concept introduction:
The amount of heat required to increase the temperature of the system by one degree is known as heat capacity. The unit to express the heat capacity is thermal energy per degree temperature.
(e)
Interpretation:
