Lesson 1.1–1.5 Notes Review: States of Matter, Model of Matter, Precision & Percent Error, Density, Heat Transfer

A set of Q&A flashcards covering states of matter, model of matter, precision/percent error, density, and heat transfer concepts from the notes.

What are the three states of matter?

Solid, liquid, and gas.

In a solid, how are the particles packed and what is the density relative to other states?

Tightly packed; high density.

In a liquid, how are the particles arranged and density relative to solids and gases?

Close together but can move past each other; medium density.

In a gas, how are the particles arranged and density relative to solids and liquids?

Far apart; low density.

How do particles move in a solid?

Vibrate in place.

How do particles move in a liquid?

Slide past each other.

How do particles move in a gas?

Move freely and quickly.

What is the volume behavior of a solid?

Fixed volume.

What is the volume behavior of a liquid?

Fixed volume; takes the shape of the container.

What is the volume behavior of a gas?

Fills the entire container; no fixed volume.

What shape does a solid have?

Definite shape.

What shape does a liquid have?

No definite shape; takes the container's shape.

What shape does a gas have?

No definite shape.

What are the four key ideas in the Model of Matter?

All matter is made of tiny particles; Particles are in constant motion; There are spaces between particles; Particles are attracted to each other.

Which instrument has the lowest precision?

Beaker.

Which instrument has higher precision for measuring volume?

Graduated cylinder.

What is the Percent Error formula?

Percent Error = |Experimental Value - Accepted Value| / Accepted Value × 100.

What is the density formula?

D = M / V.

What are the units for density in the example?

g/cm^3.

If the slope of mass vs volume is 5.0 g/cm^3, what does that represent?

The density of the metal.

What is the formula for heat transfer (q)?

q = m · c · ΔT.

How do you solve for the specific heat capacity c?

c = q / (m · ΔT).

What does ΔT stand for in the heat transfer formula?

Change in temperature.
