Problem
A sample of neon gas is confined in a rigid container whose volume does not change with temperature. The measured pressures at various Celsius temperatures are listed.
Temperature T (∘C)
0
25
50
75
100
Pressure P (kPa)
98.0
107.2
116.0
124.7
133.5
Assume that the relationship between pressure and temperature is exactly linear over this range.
(a) On appropriately labeled axes, sketch the graph of pressure P versus temperature T using the data in the table.
(b) Determine the numerical slope and vertical intercept of the straight line that best fits the data.
(c) Using your linear equation, calculate the temperature (in ∘C) at which the pressure of the gas would be zero.
(d) Express the temperature found in part (c) on the Kelvin scale.
