Which of the following describes the thermal energy of particles in a substance?
a) average value of all kinetic energy
b) total value of all kinetic energy
c) total value of all kinetic and potential energy
d) average value of all kinetic and potential energy

c. because step up transformer steps up the input voltage i.e increases the input voltage  

the number of turns are greater on the secondary side of step up transformer  

transformer does not handle dc current

because of all the things that happen around the us, many people get into arguments which sadly could get physical, but we should actually make a change for that.

substituting a hydrogen atom with a halogen in a hydrocarbon:

- the single bond remains single. a is wrong.

- the bond with hydrogen is as strong as with a halogen. c is wrong

- a hydrocarbon is saturated if there is no double bond. we do not know that so d is wrong.

- carbon will always have four valence electrons. e is wrong.

by elimination, the correct answer is b. the boiling point of the new compound increases.
