The reason there is a difference between the mass of the candle before and after burning is that <u>C. Some of the </u><u>candle wax </u><u>was </u><u>converted </u><u>into</u><u> light energy. </u>
When a candle is being burnt, the candle wax acts as a fuel for the fire. This wax is burnt by the fire such that heat and light energy are formed. The candle wax was therefore converted from chemical energy to light energy.
The other options are wrong because:
- Gases escaping won't reduce mass of candle
- Masses were not the same after the candle was burnt
- The law of conservation of mass still applies but the mass simply transferred to another form
In conclusion, the mass of the candle changed because some of the wax was converted to light energy.

Answer:
There were two main shortcomings with the Literary Digest's 1936 presidential poll:
- Sample bias: the magazine selected 10 million people out of three sources: telephone directories, club memberships, and magazine-suscriber lists. These sources gave the sample and middle an upper middle cass bias because in the epoch, few poor people owned telephones, were members of private clubs, or were suscribers of magazines.
- Nonresponse bias: Literary Digest wanted to survey 10 million people, but out of the 10 million people who received the poll, only 2.5 million people responded. This is called a nonresponse bias because the people who respond surveys have specific qualities different from the people who do not respond surveys.
Modern-pollsters tries to be more careful when selecting a sample: it should be representative of the population as a whole. Pollsters also have to deal with nonresponse bias, therefore, they try to send their surveys to people who are more likely to respond.
Believing that others are right is
to private acceptance and as conforming without believing is to public
compliance. Public compliance involves a change in behavior including the
public expression of opinions that is not accompanied by an actual change in
one’s private opinion. Thus, compliance represents what people do or say in
public, even though they believe something different in private. A driver might
follow the speed limit or wear a tie which is a behavior to conform to social
norms even though we may not necessarily believe that it is appropriate to do
so which is opinion. However, behaviors that are formerly executed out of a
desire to be accepted which is normative conformity may frequently produce
changes in beliefs to match them and the result becomes private acceptance
which is for instance a child who begins smoking to please his friends but soon
convinces himself that it is the right thing to do or a prisoner of war who
eventually accepts the political beliefs of his captor.
