Question

what is the estimated temperature, in kelvins, of the gas when its volume is 4 cubic decimeters?
a 640
b 600
c 40
d 4

Explanation:

Step1: Analyze the graph axes

The x - axis represents volume (cubic decimeters), and the y - axis represents temperature (kelvins). We need to find the temperature when volume \( x = 4 \) cubic decimeters.

Step2: Locate \( x = 4 \) on the graph

Find the point on the line where the volume (x - value) is 4. Then, check the corresponding y - value (temperature) on the y - axis. From the graph, when \( x = 4 \), the temperature (y - value) aligns with 600 kelvins (by observing the grid and the line's position).

Answer:

B. 600
