Question

physical science six week
units 1a, 1b, and 2a:

1. the kinetic molecular theory (kmt) states that:

a. as energy (temperature) increases, so does the parti
speed
b. energy cannot be created or destroyed, only conver
from one form to another
c. as you compress particles, the density will increase
d. is there even hope???

1. which one of these is a chemical property?

a. luster
b. flammability
c. boiling point
d. density
) which one of these is not a physical property?
a. ph
b. hardness
c. luster
d. viscosity
a substance made of more than one type of atom in a fix
ratio is called:
a. a heterogeneous mixture
b. a homogenous mixture
c. an element
d. a compound
which one of these is an example of a homogenous mix
a. chicken noodle soup
b. oil and

Explanation:

For question 1, the Kinetic Molecular Theory (KMT) relates temperature (energy) to particle speed. For question 2, flammability is a chemical property as it involves a chemical change (burning). For question 3, pH is a chemical property (related to acidity/basicity, a chemical characteristic), while hardness, luster, and viscosity are physical properties. For question 4, a compound has a fixed ratio of different atoms.

Answer:

1. a. As energy (temperature) increases, so does the particle speed.
2. b. Flammability.
3. a. pH.
4. d. A compound.
