Question

A balloon is heated and undergoes the following volume changes at the corresponding temperatures. Construct a graph of volume verses temperature. Determine the slope of the line generated, the y-intercept and write the equation for the relationship.

Temperature (C)

100.0

80.0

60.0

30.0

20.0

0.0

Volume (liters)

4.78

4.52

4.26

3.88

3.76

3.50

Answer 1

Answer – We are given the temp and volume data and we need to draw the graph temp Vs volume.

The graph of Temperature(^oC) Vs Volume (L) as follow –

The line equation , y = 0.0128x +3.4997

The slope of the line generated is 0.0128

y-intercept, C = 3.4997

The given data show as the temperature decrease volume also gets decreased, so the temp and volume are directly proportional to each other

T a V

So this is Charles law, V1/T1 = V2/T2
