Question: What AC format is especially known for playing Christmas music in the Christmas season?

Answer: soft AC

<hl> In recent years it has become common for many AC stations, particularly soft AC stations, to play primarily or exclusively Christmas music during the Christmas season in November and December. <hl> While these tend mostly to be contemporary seasonal recordings by the same few artists featured under the normal format, most stations will also air some vintage holiday tunes from older pop, MOR, and adult standards artists – such as Nat King Cole, Bing Crosby, Dean Martin, The Carpenters, Percy Faith, Johnny Mathis and Andy Williams – many of whom would never be played on these stations during the rest of the year.

Question: In what century was the term matter defined excluding energy phenomena like light and sound?

Answer: 20th

<hl> Before the 20th century, the term matter included ordinary matter composed of atoms and excluded other energy phenomena such as light or sound. <hl> This concept of matter may be generalized from atoms to include any objects having mass even when at rest, but this is ill-defined because an object's mass can arise from its (possibly massless) constituents' motion and interaction energies. Thus, matter does not have a universal definition, nor is it a fundamental concept in physics today. Matter is also used loosely as a general term for the substance that makes up all observable physical objects.

Question: What kind of particles make up every object in the world that can be touched?

Answer: atoms

<hl> All the objects from everyday life that we can bump into, touch or squeeze are composed of atoms . <hl> This atomic matter is in turn made up of interacting subatomic particles—usually a nucleus of protons and neutrons, and a cloud of orbiting electrons. Typically, science considers these composite particles matter because they have both rest mass and volume. By contrast, massless particles, such as photons, are not considered matter, because they have neither rest mass nor volume. However, not all particles with rest mass have a classical volume, since fundamental particles such as quarks and leptons (sometimes equated with matter) are considered "point particles" with no effective size or volume. Nevertheless, quarks and leptons together make up "ordinary matter", and their interactions contribute to the effective volume of the composite particles that make up ordinary matter.

Question: How many phases of matter are there?

Answer: four

<hl> Matter commonly exists in four states (or phases): solid, liquid and gas, and plasma. <hl> However, advances in experimental techniques have revealed other previously theoretical phases, such as Bose–Einstein condensates and fermionic condensates. A focus on an elementary-particle view of matter also leads to new phases of matter, such as the quark–gluon plasma. For much of the history of the natural sciences people have contemplated the exact nature of matter. The idea that matter was built of discrete building blocks, the so-called particulate theory of matter, was first put forward by the Greek philosophers Leucippus (~490 BC) and Democritus (~470–380 BC).

Question: What similar term is often used interchangeably with matter, although the two differ slightly in modern physics?

Answer: mass

<hl> Matter should not be confused with mass , as the two are not quite the same in modern physics. <hl> For example, mass is a conserved quantity, which means that its value is unchanging through time, within closed systems. However, matter is not conserved in such systems, although this is not obvious in ordinary conditions on Earth, where matter is approximately conserved. Still, special relativity shows that matter may disappear by conversion into energy, even inside closed systems, and it can also be created from energy, within such systems. However, because mass (like energy) can neither be created nor destroyed, the quantity of mass and the quantity of energy remain the same during a transformation of matter (which represents a certain amount of energy) into non-material (i.e., non-matter) energy. This is also true in the reverse transformation of energy into matter.
