Energy is an amount, while power is a rate at which energy is used. Energy is measured in watt-hours (WÂ·h) or joules (J). Power is measured in watts (W) or joules per second (J/s). Watt-hours are like buckets, and watts are like buckets per hour. If you have 5 buckets of energy and you pour one bucket per hour, you'll be able to pour for 5 hours before you run out.
A) Joules Degrees Celsius/Fahrenheit are a measure of temperature, the most common measures of heat energy are BTU's (British Thermal Unit), Joules, and Calories.i, D. Heat energy is in Joules, but can be measured in both celsius and fahenheit depending on which system is used. Thanks for the thumbs down, but it still can be converted so D is correct. They are still measurments of heat energy so I'll stick to my answer.
