Answer the following question given this paragraph: Summary Four quantities must be known for a complete physical description of a sample of a gas: temperature, volume, amount, and pressure. Pressure is force per unit area of surface; the SI unit for pressure is the pascal (Pa), defined as 1 newton per square meter (N/m2). The pressure exerted by an object is proportional to the force it exerts and inversely proportional to the area on which the force is exerted. The pressure exerted by Earth's atmosphere, called atmospheric pressure, is about 101 kPa or 14.7 lb/in.2 at sea level. Atmospheric pressure can be measured with abarometer, a closed, inverted tube filled with mercury. The height of the mercury column is proportional to atmospheric pressure, which is often reported in units ofmillimeters of mercury (mmHg), also called torr. Standard atmospheric pressure, the pressure required to support a column of mercury 760 mm tall, is yet. Q: What is the si unit for pressure? A:

OPTIONS:
- watt
- laurent
- le
- pascal

Answer: pascal

Problem: OPTIONS:
- protons
- more alcohol
- ions
- ketones
Q: Answer the following question given this paragraph: The carbonyl group, a carbon-to-oxygen double bond, is the defining feature ofaldehydes and ketones. In aldehydes at least one bond on the carbonyl group is a carbon-to-hydrogen bond; in ketones, both available bonds on the carbonyl carbon atom are carbon-to-carbon bonds. Aldehydes are synthesized by the oxidation of primary alcohols. The aldehyde can be further oxidized to a carboxylic acid. Ketones are prepared by the oxidation of secondary alcohols. Mild oxidizing agents oxidize aldehydes to carboxylic acids. Ketones are not oxidized by these reagents. A thiol is a compound with an SH functional group. Q: What are prepared by the oxidation of secondary alcohols? A:
Answer: ketones

Problem:OPTIONS:
- moon
- earth
- horizon
- sun

Answer the following question given this paragraph: The orbits of the planets lie in nearly the same plane. The Sun is at the center. Q: The planets orbit around what celestial body? A:
****
A: sun

Answer the following question given this paragraph: Solar energy is used to heat homes and water, and to make electricity. Scientists and engineers have many ways to get energy from the Sun ( Figure above ). One is by using solar cells. Solar cells are devices that turn sunlight directly into electricity. Lots of solar cells make up an individual solar panel. You may have seen solar panels on roof tops. The Sun's heat can also be trapped in your home by using south facing windows and good insulation. Q: The sun's heat can also be trapped in your home by using south facing windows and good what? A:
OPTIONS:
- floors
- vegetation
- curtains
- insulation
insulation

Answer the following question given this paragraph: You encounter solids and liquids in many forms in your everyday life. Solids, unlike liquids, hold a definite shape. Both solids and liquids hold a definite volume. However, on a molecular level, these two states of matter are quite different. In this lesson we will introduce some of the properties of liquids and solids that affect your interactions with the substances all around you. Q: Both solids and liquids hold a definite what? A:
OPTIONS:
- mass
- size
- shape
- volume

Answer: volume

input with options: Answer the following question given this paragraph: Q: What do you call an incomplete outer shell of an atom? A:
OPTIONS:
- helium shell
- motile shell
- nucleic shell
- valence shell
output:
valence shell
