Questions & Step-by-Step Solutions
What is the specific heat capacity of air at constant pressure? (2022)
Step 1: Understand what specific heat capacity means. It is the amount of heat energy required to raise the temperature of a unit mass of a substance by one degree Celsius (or one Kelvin).
Step 2: Recognize that there are two types of specific heat capacity: at constant volume and at constant pressure. This question asks for the value at constant pressure.
Step 3: Know that for air, the specific heat capacity at constant pressure is a known value in physics and engineering.
Step 4: Look up or recall the approximate value for the specific heat capacity of air at constant pressure, which is about 1.005 joules per kilogram per Kelvin (J/kg·K).
Step 5: Conclude that the specific heat capacity of air at constant pressure is approximately 1.005 J/kg·K.
