Answer the following question given this paragraph: The smallest and lightest alcohols (methanol, ethanol, propanol) are completely soluble in water in all proportions. In a solution, the hydroxyl groups of alcohol molecules and the water molecules form hydrogen bonds with each other, resulting in complete miscibility. However, as the length of the carbon chain increases, the solubility decreases. The solubility of 1-butanol is 7.4 g per 100 g of water, while that of 1-pentanol is 2.7 g per 100 g water, and 1-octanol is 0.06 g per 100 g water. The carbon chain portion of the larger alcohol molecule is nonpolar and leads to the decreased solubility of the overall compound. Q: The smallest and lightest alcohols (methanol, ethanol, propanol) are completely soluble in? A:
OPTIONS:
- gasoline
- oil
- argon
- water
water

Answer the following question given this paragraph: Formaldehyde is a gas at room temperature. Acetaldehyde boils at 20C; in an open vessel, it boils away in a warm room. Most other common aldehydes are liquids at room temperature. Q: What form does formaldehyde take at room temperature? A:
OPTIONS:
- solid
- liquids
- plasma
- gas

Answer: gas

Question: Answer the following question given this paragraph: Light is a wave of changing electric and magnetic fields. Light waves are caused by disturbances in an electromagnetic field, like the acceleration of charged particles (such as electrons). Light has a dual nature; at times, it acts like waves, while at other times it acts like particles, called photons . Light travels through space at the maximum speed allowed by the laws of physics, called the speed of light. Light has no mass, but it carries energy and momentum. Fermat's principle states that light will always take the path that takes the least amount of time (not distance). Q: Fermat's principle states that what will always take the path that takes the least amount of time? A:
OPTIONS:
- sound
- wind
- electricity
- light
Answer: light

OPTIONS:
- water
- oxygen
- air
- light
output: light
