Classify each of the following as energy primarily transferred as heat or energy primarily transferred as work. 1. the energy transferred from your body to a shopping cart as you push the shopping cart down the aisle. 2. the energy transferred from the flames to your hot dog when you cook your hot dog over a campfire.

answer: option (a) is the correct answer.

explanation:

the measurement of hydrogen ions in a solution is known as ph.

if ph of a solution is less than 7 then the solution is acidic. if ph of a solution is greater than 7 then the solution is basic.

when the ph of a solution equals 7, then the solution is considered as neutral.

the ph of pure water is 7, therefore, it means that concentration of hydronium ions equals that of hydroxide ions.
