Which of following statements about energy are correct select? Select all that apply. A . Energy can be created or destroyed B . Energy is the ability to do work C . Energy is a material substance D . Energy can change from one form to another E . An object can only have one from of energy at a time .

B and C

Explanation:

Energy is simply defined as the capacity to do work and according to the law of conservation of energy (first law of thermodynamics), energy can neither be created nor destroyed but can, however, be converted from one form to another.

An object can have more than one form of energy at a time. For example, a moving object possesses kinetic energy and can also possess heat energy due to the heat generated while overcoming frictional force.

Option A negates the law of conservation of energy while option D is grossly incorrect.

The correct options are B and C.

hello, i am papaguy.

i have found an answer to your question but use it as information.

information: because weak acids/bases have low concentration of hydrogen ions, the addition of water has a large impact on the ph. 2. a difference in 1 unit is a 10x difference in concentration for example; a liquid with ph of 3 is 10x more acidic than a liquid with a ph of 4. therefore, a liquid with a ph of 3 is stronger.

best of luck!

d) physical means can be used to separate the components of air.
