Lesson One Flashcards
Physics and Chemistry are both the studies of ___________ and __________ .
Matter and energy.
What two things does matter have?
Volume and mass.
What is mass?
How much stuff is inside a particular material.
Why is mass not always measured by weight.?
Because objects do not have weight in space, but they do have the same mass in space.
How can we measure volume?
By immersing an object in liquid.
Which is denser- a one-inch block of gold or a one-inch block of wood?
The cube of gold is denser because the atoms and the gold are more tightly packed together, and they are more massive.
Name as many properties of matter as you can recall.
Answers will vary; could include mass, volume, density, state of matter, viscosity, color, hardness, odor, malleability, ductility, plasticity, and reactivity.
What is viscosity?
Thickness or resistance to flow in a liquid. For example, honey has higher viscosity than water.
What is buoyancy?
The ability of something to float.
