What is the main reason that liquids take the shape of their container?

Their particles can flow past each other

Their particles are very far apart

Their particles are fixed in place

Their particles vibrate in one spot

Which of the following best describes the structure of a typical solid?

Particles are arranged in a fixed pattern and are closely packed

Particles are loosely packed and slide over each other

Particles are scattered randomly and far apart

Particles move freely and fill the entire space

What is thermal expansion?

The increase in volume of a material due to heating

The decrease in temperature of a material

The change of state from solid to liquid

The increase in pressure in a gas

What does the law of conservation of mass state?

Mass cannot be created or destroyed in a chemical reaction

Mass can be created or destroyed

Mass can change form but not change weight

Mass is only important in physical reactions

Which of the following is an example of conservation of mass?

Burning wood produces ash and gases but the mass of the original wood equals the mass of the products

Mixing salt in water makes the total mass heavier

Evaporating water makes it disappear completely

Melting ice makes the water less heavy

In a closed container, if you mix vinegar and baking soda and observe a reaction, what happens to the total mass?

The total mass remains the same before and after the reaction

The total mass cannot be measured accurately

The total mass increases due to the reaction

The total mass decreases after the reaction

When a piece of paper is burned, what happens to the mass of the paper?

The mass is transformed into ash and gases, but the total mass remains constant

The mass increases because of the heat

If you have a sealed jar with a reaction happening inside, what can you say about the mass of the substances inside the jar?

The mass of the substances will stay the same throughout the reaction

The mass will decrease as gases escape

The mass will change depending on temperature

The mass will double because of the reaction

What happens to the mass of an ice cube when it melts into water?

The mass remains the same before and after melting

The mass is lost as steam escapes

The mass decreases because water is lighter

The mass increases because ice expands

If you dissolve sugar in water, what can you say about the total mass of the sugar and water together?

The total mass remains the same before and after dissolving

The total mass increases due to the sugar

The total mass cannot be determined

The total mass decreases because sugar disappears

During a chemical reaction, how is mass conserved?

The total mass of the reactants equals the total mass of the products

Mass is absorbed from the environment

Mass is lost as energy during the reaction

What effect does cutting a piece of paper in half have on its mass?

The total mass stays the same before and after cutting

The mass increases because it becomes two pieces

The mass decreases because it is smaller

The mass changes based on how it is cut

During a chemical reaction, if one reactant is a gas, what happens to the total mass of the system if it is contained?

The mass is conserved and remains the same as long as the container is sealed

The mass decreases as gas escapes

The mass increases because of gas pressure

The mass is lost during the reaction
