What is a quanitive and qualitive observation?
Quanitive observation is the mathematical aspect of the experiment, such as the amount of water used or the height of a plant. Qualitive observation is using descriptions and words to describe parts of the experiment. One example is the chemical color change of a gas (what shade of color does it have?)
Is it a chemical change physical change chemical property or physical property when hydrogen chloride is a gas at room temperature.?
The observation that hydrogen chloride is a gas at room temperature is a PHYSICAL property.
A qualitive observation?
A qualitive observation is an observation of a product of a reaction which cannot be measured numerically, e.g. colour, state of matter. A quantitive observation is an observation which can be measured, e.g. size, volume.
What are the differences between laboratory observation and naturalistic observation?
Laboratory observation takes place in a controlled environment where researchers manipulate variables, while naturalistic observation occurs in the subject's natural environment without interference. Laboratory observation allows for more precise control over variables and conditions, whereas naturalistic observation provides insights into real-world behaviors and interactions.
What is a word for an interpretation of an observation?
Inference is a word for an interpretation of an observation
Example of activity using observation as scientific method?
Observing a change in state of matter is a observation that could be made and recorded.
When was chemical change discovered?
This is a very old observation, from the prehistoric times.
How did the scientific revolution change how scientists did their work?
they relied more on observation
What does a quantitative observation mean?
This means an observation where you take a numerical measurement, as opposed to a qualitative one where you notice something else, like a color change.
What does it mean to change objects and events and compare them to the original objects and events?
observation
How did the scientfic revolution change the way scientist did their work?
they relied more on observation.
How did the scientfic revolution change the way scientists did their work?

How did the scientific change the way scientists proved their ideas?

What are two observations you might make when a physical change occurs?
Change in state: One observation would be a change in the physical state of the substance, such as from solid to liquid or gas. Reversibility: Another observation might be that the physical change is typically reversible, meaning the substance can return to its original state by reversing the process that caused the change.
What are four inicators that a chemical change has taken place?
Color Change Temperature change Observation of gas being released (bubbles) Formation of a precipitate
When the candle was lit a pool of liquid wax formed in the area around the wick and then spilled over the side and solidified does this observation reefer to a physicalor a chemical change?
This observation refers to a physical change. The melting and solidifying of the wax is a reversible process that does not change the chemical composition of the wax molecules.
How did the scientific Revolution change the way scientists proved their ideas?
