Question
![**Heating Nitrogen in a Closed Rigid Vessel**
In this problem, 2 kg of nitrogen is heated in a closed rigid vessel. The initial temperature of the nitrogen is \( T_1 = 20 \,^\circ\text{C} \), and it is heated to a final temperature of \( T_2 = 120 \,^\circ\text{C} \). The task is to determine the amount of heat transferred, measured in kilojoules (kJ).
Considerations for solving this problem include understanding the properties of nitrogen, the process of heating in a rigid container, and the application of the specific heat capacity formula to calculate the heat transferred:
\[ Q = m \cdot c \cdot \Delta T \]
Where:
- \( Q \) is the heat transferred (in kJ)
- \( m \) is the mass of the substance (in kg)
- \( c \) is the specific heat capacity (in kJ/kg·K)
- \( \Delta T \) is the change in temperature (in K)](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2F00030fb4-2bf0-41c7-8151-28e1f2b4f688%2F417bc2fc-b96d-4e40-9b02-5fad5ebaba2f%2F3xqbmre_processed.jpeg&w=3840&q=75)
