This is a plastic cylinder used to measure liquid.
what is a syringe
This law tells us that the volume of gas increases as the temperature increases.
What is Charles' Law?
It is the "P" in the ideal gas law equation.
What is pressure?
Formed by a reaction between an acid and a base, this common ionic compound has the formula NaCl.
What is salt?
Defined as using one or more of your senses to gather information, it is generally the first step in the scientific method.
What is the observation question?
Coated with a universal indicator, this paper changes color to identify whether a substance is an acid or a base?
What is pH paper
This law states that the pressure of a gas is inversely proportional to its volume, as long as the temperature remains constant.
What is Boyle's Law?
In an experiment, these are the factors, traits, or conditions that can exist in differing amounts or types.
What are variables?
What is the gas formed when baking soda and vinegar are mixed?
What is carbon dioxide or CO2?
This final step of an experiment summarizes the results and states whether the data supports or rejects the hypothesis.
What is a conclusion?
Commonly used in lab experience and found in kitchens, this device is used to measure the heaviness of an object.
What is a scale?
According to Charles's Law, if temperature increases, this variable also increases.
What is Volume?
When a lighted candle is covered by a glass in a dish of water, the combustion consumes oxygen, creating this, which causes the water to be forced up into the glass.
What is change in pressure or low pressure?
This process occurs when liquid water is changed to a gas.
What is evaporation?
In the scientific method, this essential step is an educated guess or a testable answer to a scientific question.
What is a hypothesis?
Galileo is credited with inventing the first instrument to measure temperature know by this 11 letter name.
What is a thermometer
This law is known as P1V1=P2V2
What is the Boyle's Law?
This is the term for a reaction that absorbs energy, often causing the surrounding temperature to decrease.
What is an Endothermic reaction?
Because the salt retains its chemical identity and can be recovered by evaporating the water, this dissolving process is known as this type of change, not a chemical one.
What is physical change?
This is the variable that is intentionally changed during the procedure of an experiment.
What is the independent variable?
"This object, typically secured over a cut-off water bottle, acts as a 'diaphragm' to demonstrate Boyle’s law."
What is a balloon?
What temperature scale must be used in all gas law calculations?
What is Kelvin?
Formed by one or more atoms held together by chemical bonds, these are the smallest particles of a chemical compound.
What is a molecule?
Common in kitchens, this white powder with the formula NaHCO3 is used as a leavening agent in baking and to neutralize acids.
what is sodium bicarbonate or baking soda?
Plural term for facts, statistics, or items of information collected together for analysis.
What is data?
