Final answer:
The energy consumed by an 1,800 W blow dryer in 4 minutes is calculated using the formula E = P × T, which results in 432,000 joules (or 432 kJ), when converting 4 minutes to 240 seconds.
Step-by-step explanation:
To find the energy consumed by a blow dryer in 4 minutes, we need to know the power rating of the blow dryer and apply the formula for electrical energy consumption. Unfortunately, the power rating isn't given in the question. However, using the typical power rating for blow dryers which is around 1,800 W as mentioned in the reference material, we can still make an estimation.
The formula to calculate energy is Energy (E) = Power (P) × Time (T), where E is energy in joules (J), P is the power in watts (W), and T is the time in seconds (s). First, we need to convert the time from 4 minutes to seconds, which gives us 240 seconds (4 minutes × 60 seconds/minute). Then we can calculate the energy consumed.
For an 1,800 W blow dryer running for 4 minutes (240 seconds), the calculation would be: E = 1,800 W × 240 s = 432,000 J (or 432 kJ).
This calculation estimates the energy consumed by the blow dryer in the given time frame, assuming it was operating at its maximum power rating throughout the entire duration.
