Answer the following question given this paragraph: The stomach is a sac-like organ at the end of the esophagus. It has thick muscular walls that contract and relax to squeeze and mix food. This helps break the food into smaller pieces. It also helps mix the food with enzymes and other secretions in the stomach. For example, the stomach secretes the enzyme pepsin, which helps digest proteins. Q: What is a sac-like organ at the end of the esophagus? A:

OPTIONS:
- appendix
- larynx
- spleen
- the stomach

Answer: the stomach

Problem: OPTIONS:
- vein pressure
- blood force
- artery pressure
- blood pressure
Q: Answer the following question given this paragraph: Q: What is generated when a heart ventricle contracts? A:
Answer: blood pressure

Problem:OPTIONS:
- heat gas
- cold gas
- fast gas
- ideal gas

Answer the following question given this paragraph: An ideal gas is one that follows the gas laws at all conditions of temperature and pressure. To do so, the gas would need to completely abide by the kinetic-molecular theory. The gas particles would need to occupy zero volume and they would need to exhibit no attractive forces what so ever toward each other. Since neither of those conditions can be true, there is no such thing as an ideal gas. A real gas is a gas that does not behave according to the assumptions of the kinetic-molecular theory. Fortunately, at the conditions of temperature and pressure that are normally encountered in a laboratory, real gases tend to behave very much like ideal gases. Q: What is the term for a gas that completely abides by the kinetic-molecular theory? A:
****
A: ideal gas

Answer the following question given this paragraph: Convection is the transfer of heat by a current. Convection happens in a liquid or a gas. Air near the ground is warmed by heat radiating from Earth's surface. The warm air is less dense, so it rises. As it rises, it cools. The cool air is dense, so it sinks to the surface. This creates a convection current, like the one in Figure below . Convection is the most important way that heat travels in the atmosphere. Q: What is the transfer of heat by a current? A:
OPTIONS:
- radiation
- combustion
- diffusion
- convection
convection

Answer the following question given this paragraph: Just as the burning of wood releases energy in the form of heat, many other chemical reactions also release heat. There are also chemical reactions, such as photosynthesis in plants, which absorb energy in the form of heat. The study of energy changes in chemical reactions is called thermochemistry . The broader term thermodynamics also looks at how heat, work, and various forms of energy are related to one another. In this lesson, we will study the difference between reactions that absorb versus release heat as well as how to measure this change in energy. Q: What branch of physical science looks at how heat, work, and various forms of energy are related to one another? A:
OPTIONS:
- photosynthesis
- frigidity
- transformations
- thermodynamics

Answer: thermodynamics
