Why are moral or ethical questions NOT testable? A. They are questions that are impossible to answer. B. They are better answere
Radda [10]

Answer:

<u>C. The answers depend on people's opinions, not on observations.</u>

Explanation:

Morals are what people <em>think</em> is the right or wrong behavior and the <em>goodness</em> or <em>badness</em> of a character.

Ethics are <em><u>morals</u></em> that <em><u>govern</u></em> a person.

So the answer is C because these answers cannot be seen from the outside.

For example: A PERSONALITY TRAIT is something you can't really see. A PHYSICAL TRAIT is something you <em>can</em> see.

Ethics and morals are like personality traits.

what was the initial pressure of 14.8 mL of gas at 75.5 C , when it occupied a volume of 16.5 mL at 70.2 C and 101.3 kPa?
OLEGan [10]

Answer:

1038.96 kPa

Explanation:

We’ll use the ideal gas law; P1V1/T1 = P2V2/T2

P1*14.8/75.5 = 101.3*16.5/70.2

P1 = (101.3 * 16.5 * 75.5) / (70.2 *14.8)

P1 = 1038.96

The heating curve shows the energy gain of a substance as it changes from solid to gas. Which section of the graph shows the liq
Schach [20]

Answer:

C. C

Explanation:

The heating curve is a graphical representation shows that how different phases of substances change as it is influenced by the increase in temperature or heat.

Section A represents solid phase, Section B represents solid-liquid phase, section C represents liquid phase, section D represent liquid-gas phase and section E represents gas phase.

Section C of the graph shows the liquid phase of the substance gaining kinetic energy. During Phase C, heat energy is absorbed and liquid particles gain kinetic energy to change into gas form that is section E.

Hence, the correct option is C.C.
