Question: Answer the following question given this paragraph: rates The rates at which reactants are consumed and products are formed during chemical reactions vary greatly. We can identify five factors that affect the rates of chemical reactions: the chemical nature of the reacting substances, the state of subdivision (one large lump versus many small particles) of the reactants, the temperature of the reactants, the concentration of the reactants, and the presence of a catalyst. Q: The presence of what, which acts as a trigger, affects the rate of chemical reaction? A:
OPTIONS:
- friction
- heat
- light
- catalyst
Answer: catalyst

input with options: Answer the following question given this paragraph: The pressure of a sample of gas is measured with an open-end manometer, partially shown to the right. The liquid in the manometer is mercury. Assuming atmospheric pressure is 29.92 in. Hg, determine the pressure of the gas in: (a) torr (b) Pa (c) bar. Q: The pressure of a sample of gas is measured with an open-end what? A:
OPTIONS:
- thermometer
- barometer
- altimeter
- manometer
output: manometer

Q: Answer the following question given this paragraph: The process in which a liquid changes to a solid is called freezing . The temperature at which a liquid changes to a solid is its freezing point. The freezing point of water is 0C (32F). Other types of matter may have higher or lower freezing points. For example, the freezing point of iron is 1535C. The freezing point of oxygen is -219C. Q: What is the process by which a liquid changes to a solid? A:

OPTIONS:
- melting
- vaporizing
- boiling
- freezing

A: freezing

input: OPTIONS:
- accumulation
- conductivity
- power
- radioactivity Now, answer this question: Answer the following question given this paragraph: Radioactivity is the ability of an atom to emit charged particles and energy from its nucleus. The charged particles and energy are called by the general term radiation. Q: What is the ability of an atom to emit charged particles and energy from its nucleus called? A:
A:
output: radioactivity

Answer the following question given this paragraph: You can see several examples of people or things in motion in Figure below . You can probably think of many other examples. You know from experience what motion is, so it may seem like a straightforward concept. Motion can also be defined simply, as a change in position. But if you think about examples of motion in more depth, you'll find that the idea of motion is not quite as simple and straightforward as it seems. Q: What can be defined simply, as a change in position? A:

OPTIONS:
- velocity
- gravity
- speed
- motion

Answer: motion

Q: Answer the following question given this paragraph: Q: A complex interactions of hormones result in an edible fruit that entices animals that help disperse what? A:

OPTIONS:
- pests
- water
- rocks
- seeds

A:
seeds
