- The higher the density of the medium,
the smaller is the weight of object X
- The lower the density of the medium,
the greater is the weight of object X
Hypothesis

17. The longer the wire,
the dimmer the bulb.
The shorter the wire,
the brighter the bulb.

18. Factors Affecting the Rate of Transpiration
Manipulated variables
Responding variables
Fixed variables
1. LIGHT
2. TEMPERATURE
3. WIND
4. HUMIDITY
Light, Temperature, Humidity, time
size and type of plant
Presence of wind
Rate of transpiration
/ difference in weight of the apparatus
Hypothesis – Windy condition
increases the
rate of transpiration
Observation
The water loss is more for the
potometer that is subjected to wind.
Conclusion
The rate of transpiration is
faster if wind is present.
