Step 1 = Unscramble the Keywords and Mixed Definitions sheet:

o   Kinaesthetic Learners = Cut and Stick

o   Visual Learners = type out and blog

 

Step 2 =   Check your keywords by using one of the following online games.  Mark each keyword with a red pen.  Correct any mistakes.

Objective 4.5

 Kettle

10 squares = 2000J/s therefore 1 square = 200J/s

Wasted Heat = 2 squares = 400J/s

Useful Heat = 5 squares = 1000J/s

Wasted sound = 3 squares = 600J/s

 

Efficiency = Useful Eout / Total Ein x 100

Efficiency = 1000 / 2000 x 100

Efficiency = 50%

 

Computer

Conservation of energy so…

Total Ein = Total Eout

150J = 20 + 10 + Useful Eout

Useful Eout = 120J

 

Efficiency = Useful Eout / Total Ein x 100

Efficiency = 120 / 150 x 100

Efficiency = 80%
