Answer:

-149.0K

Explanation:

Charles's law states that the volume of a gas is directly proportional to the absolute temperature under constant pressure.

The equation is:

V1/T1 = V2/T2

Where V1 is initial volume = 6.00L

T1 is absolute initial temperature = 25.0°C + 273 = 298K

V2 is final volume = 2.50L

T2 is our incognite

Replacing:

6.00L/298K = 2.50L/T2

T2 = 2.50L * 298K / 6.00L

T2 = 124.17K

The temperature is 124.17K - 273.15K =

Transform boundaries are places where plates slide sideways past each other. At transform boundaries lithosphere is neither created nor destroyed. Many transform boundaries are found on the sea floor, where they connect segments of diverging mid-ocean ridges. California's San Andreas fault is a transform boundary. So its true
