4. How many joules of heat energy does it take to burn off 500 000 cal of potato chips? (1 cal = 4.184 )) Show your work.

Explanation:

Hello.

In this case, we need to perform a unit conversion problem between cal and joule, taking into account that 1 cal equals 4.184 joules of energy, therefore, we write the following proportional factor:

Whereas the 1 cal is written under the line in order to simplify the initial can and the 4.184 J on the line as joules are the required units. Thus, we obtain:

As the energy required to burn off such amount of energy given of potato chips.

Best regards.
