Physical Properties
- E.
Solubility
Correct Answer
D. Physical PropertiesExplanation
Physical properties are characteristics of a substance that can be observed or measured without changing the substance into something else. These properties include mass, which is the amount of matter in an object, and matter itself, which refers to anything that occupies space and has mass. Chemical reactions, on the other hand, involve the transformation of one substance into another, so they do not fall under the category of physical properties. Solubility, while it can be observed without changing the substance, is a specific property related to the ability of a substance to dissolve in another substance, so it is also considered a physical property.Rate this question:

What process is the opposite of evaporation?
- A.
Sublimination
- B.
Precipitation
- C.
Condensation
- D.
Boiling point
- E.
Air pressure
Correct Answer
C. CondensationExplanation
Condensation is the process opposite to evaporation because it involves the conversion of a gas or vapor into a liquid. During condensation, the molecules lose energy and come closer together, forming liquid droplets. This process occurs when the temperature of a gas or vapor decreases, causing it to change state. In contrast, evaporation is the process by which a liquid changes into a gas or vapor, typically due to an increase in temperature. Therefore, condensation is the correct answer as it is the opposite process to evaporation.Rate this question:

What state of matter does not have a definitive shape or volume?
Correct Answer
gasExplanation
Gas is a state of matter that does not have a definitive shape or volume. Unlike solids and liquids, gas particles are not tightly packed and can move freely, filling the space available to them. This allows gases to take the shape and volume of their container. The particles in a gas are in constant motion, colliding with each other and the walls of the container. Therefore, gas does not have a fixed shape or volume and can expand or contract depending on the conditions it is subjected to.Rate this question:

- A.
Created
- B.
Destroyed
- C.
Created and Destroyed immediately after.
- D.
Neither Created nor Destroyed.
- E.
It depends on the scientific experiment and which substances you are using.
Correct Answer
D. Neither Created nor Destroyed.Explanation
During a physical or chemical change, matter is not created or destroyed, but rather transformed from one form to another. This is known as the law of conservation of mass, which states that the total mass of a closed system remains constant over time. Therefore, the amount of matter present before and after the change will be the same, even though it may have undergone a physical or chemical transformation.Rate this question:

Power
- D.
Position
- E.
Momentum
Correct Answer
E. MomentumExplanation
Momentum is the product of an object's weight and mass, and it is a measure of how hard it is to slow down or stop an object. Momentum depends on both the mass and velocity of an object. The greater the mass or the higher the velocity, the greater the momentum. This is because an object with more mass or higher velocity has more inertia and requires more force to change its state of motion. Therefore, momentum can be considered as a measure of an object's resistance to changes in its motion.Rate this question:

- A.
Gravitational pull
- B.
Inertia
- C.
An orbit
- D.
Universal force
- E.
Law of the universe
Correct Answer
C. An orbitExplanation
An orbit refers to the path that a body in space follows as it revolves around another body. It is the result of the gravitational pull between the two bodies, which causes the orbiting body to continuously fall towards the central body while also moving forward. This combination of falling and forward motion creates a curved path known as an orbit. Inertia, gravitational pull, and the universal force are all factors that contribute to the formation and maintenance of an orbit. However, an orbit itself is the specific term used to describe this path.Rate this question:

Correct Answer
B. They are in limited supplyExplanation
Fossil fuels are considered nonrenewable resources because they are in limited supply. This means that once they are used up, they cannot be replaced within a human lifespan. Fossil fuels, such as coal, oil, and natural gas, are formed over millions of years from the remains of ancient plants and animals. The process of their formation is extremely slow, making it impossible for them to be replenished at the same rate they are consumed. Therefore, their availability is finite, making them nonrenewable resources.Rate this question:
