The pictures show four items from around the house that transform energy.
Match each object with the correct type of energy transformation.
Column A
1.
Q:
a
Q
2.
R:
R
3.
S:
S
4.
T:
d
T
Column B
a.chemical to light and heat
b.electrical to mechanical and sound
c.electrical to sound and light
d.electrical to heat
1. Q: c (electric fan turning electrical energy into mechanical motion and sound)
2. R: b (electric drill converting electrical energy into mechanical motion and sound)
3. S: a (candle converting chemical energy into light and heat)
4. T: d (toaster converting electrical energy into heat)
To match each object with the correct type of energy transformation, we can analyze the descriptions of the objects and their corresponding types of energy transformation.
Column A:
1. Object: [Q]
Energy Transformation: [a.chemical to light and heat]
2. Object: [R]
Energy Transformation: [c.electrical to sound and light]
3. Object: [S]
Energy Transformation: [b.electrical to mechanical and sound]
4. Object: [T]
Energy Transformation: [d.electrical to heat]
Therefore, the correct matches are:
1-Q with a
2-R with c
3-S with b
4-T with d
