Comparison between boiling and Evaporation – (Process)Similarities:-Similarities:-Boiling and evaporation (Both) are a process in which
liquid changing into a gas and heat is absorbed.Differences:-Differences:- Evaporation takes place at all temperatures below
boiling point but boiling takes place at the boiling point only.
Evaporation is a slow process, boiling is a very fast process
- Evaporation - takes place from the surface of the liquid. - Boiling – throughout the liquid.
CARA MENJAWAB..
USE WHAT AND WHY..
Renal artery has thicker wall because it carries blood in higher pressure.
WHAT
WHY
Knowing the limitation of measuring apparatus
35
34
= 34.2cm³
or 34.2 ml
Measuring cylinder can Measure the volume of liquidup to 0.1 ml accuracy.
CALCULATION Step 1 – write down the formula Load X distance of load = effort X distance of effort
Step 2 – substitute with the relevant values 5 N X 16 cm = Effort X 20 cm
Step 3 – solve the problem to get the answer Effort = 5N X 16 cm 20 cm Effort = 10 N
WORK DONE Work done =Force (N) X Distance (m) Work done = (52+28)x10N X 10 m = 800 N X 10 m = 8000Nm = 8000J = 8 KJ
From QUESTION
Both the iron and glass are heated simultaneously. The time taken for thumbtack drop is recorded.
manipulated
responding
A student carried out an experiment to study the affect of light intensity on the rate of photosynthesis.
Manipulated :
Responding :
Light intensity
Rate of photosynthesis
Example:……
Variables :-a.Constant – Base areab.Manipulated – Position of centre of gravity
( )c.Responding – Stability of object
Position of centre of gravity affects the stability of object
Hypothesis ????
2. The lower / higher / increase / decrease ______
** Gunakan manipulated V dahulu, diikuti dengan responding V ……
Hypothesis: The conductivity of heat increase, time taken for thumbtack fall down decrease
Manipulated
Responding
The higher the centre of gravity (variable that is manipulated)
The less stable the object (variable that respond)
The lower the centre of gravity (variable that is manipulated)
The more stable the object (variable that respond)
INFERENCE
________ _______ because ___________.
What how ( responding v) why ( manipulated )
