Question

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

a. as energy (temperature) increases, so does the particle speed
b. energy cannot be created or destroyed, only converted 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

1. which one of these is not a physical property?

a. ph
b. hardness
c. luster
d. viscosity

1. a substance made of more than one type of atom in a fixed ratio is called:

a. a heterogeneous mixture
b. a homogenous mixture
c. an element
d. a compound

1. which one of these is an example of a homogenous mixture?

a. chicken noodle soup
b. oil and vinegar salad dressing

Explanation:

1.

The Kinetic Molecular Theory (KMT) describes the behavior of particles in matter. One of its key points is that as energy (temperature) increases, particle speed increases. Option b is the law of conservation of energy (not KMT), option c is more about density - particle relationship not KMT's main focus, and option d is a non - scientific statement.

A chemical property is a characteristic of a substance that is observed during a chemical reaction. Flammability is a chemical property as it involves a substance reacting with oxygen (burning). Luster (a physical property related to appearance), boiling point (a physical property related to state change), and density (a physical property related to mass and volume) are physical properties.

A physical property can be observed without changing the substance's chemical composition. pH is a chemical property as it relates to the acidity or basicity of a substance (a chemical characteristic). Hardness (related to physical resistance), luster (appearance), and viscosity (flow property) are physical properties.

Answer:

a. As energy (temperature) increases, so does the particle speed
