The volume of a gas is directly related to the temperature of the gas. at 30 degrees celsius a certain gas has a volume of 125 cubic centimeters. what will the new volume be at 50 degrees celsius? a) 75 cubic cm b) 83 1 3 cubic cm c) 166 2 3 cubic cm d) 208 1 3 cubic cm

Use the direct variance formula:

V = kt, in which:

v = volume

k = constant of proportion

t = temperature

When the Celsius is 30 degrees, the volume is 125. Plug it into the formula

V = kt

125 = 30(k)

Isolate the k. Divide 30 from both sides

125/30 = 30k/30

k = 125/30

k = 4.167 (rounded).

Plug in 4.167 for k for the equation, and solve for 50 degrees.

V = kt

V = (4.167)(50)

Simplify

V = 208.35

D)208 1/3 cubic cm is your closest answer

hope this helps
