The type of container
b)
The length of time the spoons stayed in the water
c)
The type of spoon
d)
The temperature of the water

10.
A student made several attempts to turn on a light using a simple circuit. The students made the conclusion that the circuit must be closed in order for the light to turn on. Is the student's conclusion reasonable?
a)
Yes, because all conclusions are correct.
b)
Yes, because circuits must be closed in order for the electricity to flow through them.
c)
No, because the circuit must be open in order for electricity to flow through it.
