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.

in chemistry, adhesion and cohesion are attractive forces that exist between molecules. they hold the molecules together from each other. they are different in that adhesive force exists between molecules of different substance while cohesive force happens between molecules of same substance.

adhesion between water and glass causes water molecules at the edge of water and glass interface to climb up the wall in a narrow glass tube. this is called capillary action. cohesion is what gives glass its shape and causes water to form a droplet.
