Final answer:
A pair of 800W hair straighteners transfer 800 Joules of energy every second.
Step-by-step explanation:
To calculate the amount of energy transferred by a pair of 800W hair straighteners every second, we use the formula:
Energy = Power x Time
Given that the power of each hair straightener is 800W, and the time is 1 second, we can substitute these values into the formula:
Energy = 800W x 1s = 800 Joules
Therefore, a pair of 800W hair straighteners transfer 800 Joules of energy every second.
