Convert between energy units. c. 4.99 × 10 3 kJ to kWh

Hey everyone, we're asked to perform the following conversion from Tillage Jules, two kilowatt hour. Now we've learned that one kilowatt hour Is going to contain 3.6 times 10 to the six jewels and we can go ahead and use this to answer our question Starting off with 1.04, 9 times 10 to the four killer jewels Will convert our killer jewels into jewels and we know that we have 10 to the third jewels per one kg jewels Plugging in our 3.6 times 10 to the six jewels. And we have this per one kilowatt hour. Now when we calculate this out, We end up with a value of 2.91 kilowatt hour, which is going to be our final answer. So I hope this made sense and let us know if you have any questions.

Key Concepts

Here are the essential concepts you must grasp in order to answer the question correctly.

Energy Units

Energy can be measured in various units, with kilojoules (kJ) and kilowatt-hours (kWh) being common in chemistry and electrical contexts. A kilojoule is a unit of energy equal to 1,000 joules, while a kilowatt-hour is the energy consumed by a power of one kilowatt running for one hour, equivalent to 3.6 million joules.

Conversion Factors

To convert between different energy units, specific conversion factors are used. For instance, to convert kJ to kWh, one must know that 1 kWh equals 3.6 million joules. Therefore, the conversion involves dividing the energy in kJ by 3,600 to obtain the equivalent in kWh.

Dimensional Analysis

Dimensional analysis is a mathematical technique used to convert units by multiplying by conversion factors that cancel out unwanted units. This method ensures that the final answer is in the desired unit, making it a crucial tool for solving problems involving unit conversions in chemistry.
