Answer:

165 °C

Explanation:

Given data

  • Initial pressure (P₁): 660 kPa
  • Initial temperature (T₁): 602 °C
  • Final pressure (P₂): 330 kPa
  • Final temperature (T₂): ?

Step 1: Convert the initial temperature to Kelvin

When working with gases, we always have to use the Kelvin scale. We can convert from Celsius to Kelvin using the following expression.

[tex]K = \°C + 273.15\\K = 602 + 273.15 = 875 K[/tex]

Step 2: Calculate the final temperature

We will use the Gay-Lussac's law.

[tex]\frac{P_1}{T_1} =\frac{P_2}{T_2}\\T_2 = \frac{P_2 \times T_1 }{P_1} = \frac{330 kPa \times 875K }{660kPa}=438K[/tex]

Step 3: Convert the final temperature to Celsius

[tex]K = \° C + 273.15\\ \° C = K - 273.15 = 438 - 273.15 = 165 \° C[/tex]
