Question

At 0°C, the volume of a gas is 22 liters. For each degree the temperature T (in degrees Celsius) increases, the volume V (in liters) of the gas increases by 2/25. Write an equation that represents the volume of the gas in terms of the temperature.

Answer 1

V=(2/25)x + 22
when x=0 the volume is equal to 22.
when x=1 the volume is equal to 22 +2/25
when x=2 the volume is equal to 22+2/25*2, etc.
So, each degree increases in temperature, the volume is increasing by 2/25 cubic liters.
