Q
A
- PV= k T
- when pressure or volume of an ideal gas tends to zero–> temperature must also tend to 0 as the two are directly proprtional
- the temeprature scale with this zero of temperature is the kelvin scale (absolute scale)
5
Q
A
- large number of molecules in random motion
- forces between particles are negligable, except during collisions
- partciles occupy negligable volume compared to volume of gas
- collisions are perfeclty elastic
- time of a collision is negligable compared to time between collisions

Q
A
- draw worst line of fir through bars
- determine a new value for absolute zero and find difference between this value and new intercept
10
Q
A
- ensure largest possible proportion of flask is immersed
- make colume of tubing small compared to volume of flask (makes calculation more accurate)
- remove heat source and stir water to ensure water at uniform temperature throughout
- allow time for heat energy to conduct through glass to air before reading temperature
