Q: Answer the following question given this paragraph: When water is heated in the boiler, it expands. It might burst the pipes of the system if it weren't for the expansion tank. This tank holds excess water after it expands. Q: What happens to water when it is heated in the broiler? A:
Answer: it expands

Answer the following question given this paragraph: However, despite this secrecy several contributions were made to modern-day chemistry. Early acids and bases were discovered, and glassware for running chemical reactions was developed. Alchemy helped improve the study of metallurgy and the extraction of metals from ores. More systematic approaches to research were being developed, although the idea of orderly scientific experimentation was not yet well-established. The groundwork was being laid for the development of chemistry as a foundational science. Q: What was the early study of chemistry called? A:
****
A: alchemy

Answer the following question given this paragraph: All life relies on a relatively narrow range of pH, or acidity. That's because protein structure and function are very sensitive to pH. Air pollution can cause precipitation to become acidic. Nitrogen and sulfur oxides, mainly from motor vehicle exhaust and coal burning, create acids when they combine with water in the air. The acids lower the pH of precipitation, forming acid rain . If acid rain falls on the ground, it may damage soil and soil organisms. If it falls on plants, it may kill them (see Figure below ). If it falls into lakes, it lowers the pH of the water and kills aquatic organisms. Q: When the ph of precipitation is lowered because of air pollution, what results? A:
OPTIONS:
- abnormal rain
- climate change
- sleet
- acid rain
acid rain

Answer the following question given this paragraph: Ground subsidence is a consequences of groundwater overuse. Q: Ground subsidence is a consequences of the overuse of what? A:
OPTIONS:
- plants
- chemicals
- topsoil
- groundwater

Answer: groundwater

input with options: Answer the following question given this paragraph: Liquid water is formed when water vapor condenses (i. e. , H 2 O(g) H 2 O(l) or when ice melts (i. e. , H 2 O(s) H 2 O(l)). Because water is a molecular substance, it is a poor conductor of electricity in its pure form. However, as we will see later, its conductivity can be improved by the addition of certain substances. Water molecules are polar, and this overall polarity gives rise to many of the properties of water. For example, an interesting effect is seen when water is placed in a static electric field, as shown in the Figure below and the video below. This phenomenon can be explained in terms of the polarity of water molecules. Q: What is type of substance is formed when water vapor condenses or when ice melts? A:
OPTIONS:
- toxic water
- chemical water
- gaseous water
- liquid water
output:
liquid water
