Final answer:
To determine the heat transfer in an isobaric process, use the formula Q = m * c * ΔT, where Q is the heat transfer, m is the mass, c is the specific heat capacity, and ΔT is the change in temperature. Calculate the change in temperature by subtracting the initial temperature from the final temperature. Determine the specific heat capacity of the refrigerant by multiplying the molar specific heat capacity by the molar mass. Plug in the values into the formula to find the heat transfer.
Step-by-step explanation:
When the pressure remains constant in a process, it is called an isobaric process. In this case, the refrigerant-134a undergoes an isobaric process from -10°C to 40°C. To determine the heat transfer for this process, we can use the equation:
Q = m * c * ΔT
where Q is the heat transfer, m is the mass of the refrigerant, c is the specific heat capacity of the refrigerant, and ΔT is the change in temperature. First, we need to find the change in temperature:
ΔT = final temperature - initial temperature = 40°C - (-10°C) = 50°C
Next, we need to find the specific heat capacity of refrigerant-134a. The specific heat capacity can be found in a reference table or by using the molar specific heat capacity multiplied by the molar mass:
c = C * M
where c is the specific heat capacity, C is the molar specific heat capacity, and M is the molar mass.
Finally, we can calculate the heat transfer:
Q = m * c * ΔT
