bi)The boiling point of a liquid is the temperature
at which the vapor pressure of the
liquid equals the pressure surrounding the liquid
liquid changes into a vapor.
bii) impurities increases the temperature range a
substance can exist as a liquid
SLOPE(s)=(LogT2*10^-2 – LogT1*10^-2)(/Log L2 *10^-1 – LogL1*10^-1)
i)ensured supports of pendula were rigged
ii)avoided parallax error on meter rule/stop watch
simple harmonic motion is the motion of a body whose acceleration is always direct towards a fixed point and is proportional to the displacement from the fixed points
0079 shown on graph with corresponding Log L read L correctly determined
i)ensured clean/tight terminals
ii)open key when reading was taken
3bi)As × increases the Brightness of the bulb increases, voltage and current through the bulb increases hence brightness increases.
3bii)Electrical device that do not obey ohm’s law are..:
