Sp Heat Capacity Q = m X Lf or P t = m x Lf
Q= mxc x∆t VIt = m X Lf
Pt =mxcx∆t Sp Latent Heat of Vaporisation
VIt=mxcx∆t Q = m x Lv or Pt = m x Lv

1.General Physics
1.1 Length and time The use of measuring cylinder for volume
The Use of rules to measure length
Submultiples of m
1cm=10 -2 m
1mm=10-3m
1um=10-6 m
1nm= 10-9 m
1km=1000 m
How measurements are done:
Stare directly above a ruler

, 1.2 Speed, velocity and acceleration
Speed is the distance travelled in unit time.
Speed-time graphs
Start to Point A- Constant speed To find distance- find area under
