Unit 1

100

Two gasses are placed in a container that reaches thermal equilibrium of 283 K. Describe the kinetic energy of the gasses.

Both gasses have the same average kinetic energy because they are at the same temperature

200

Which graph best represents the best thermal equilibrium graph to represent mixing 200mL of 90°C water with 50mL of 20°C water?

C - there is a larger volume of the higher temperature water, the equilibrium temperature will be closer to the higher temperature water.

300

What are three ways to increase the volume of a balloon.

1. The number of particles increases

Lower pressure outside balloon

Warm the balloon

400

What is the volume of a balloon that contains 2 moles of carbon at 3 atm and 400 K?

21.89 L

Unit 2

100

List three intensive properties

Mass, volume, length

200

A sample of calcium has a mass of 80 g, how many moles are present?

2 moles ca

300

According to Kinetic molecular theory as temperature increases pressure increases because the particles move _________ colliding with the wall of the container _________ frequently.

Faster, more

400

1. Lithium is a metal that is shiny and malleable. Is this description physical or chemical properties?

Physical

Unit 3

100

Why cannot extensive properties be used to identify a substance?

They do change based on amount so it tells you almost nothing about composition without further study

200

You are not allowed to eat sugar. You sneak some sugar into your tea. Your parents walk into the room, see the sugar, and ground you. List three things you could have done to avoid being grounded.

1. Crush the sugar (decrease the particle size)

        Heat the water

        Stir the tea

300

When a small volume of water is boiled, a large volume of steam is produced. Why?

The molecules are further apart for the steam.

Unit 4

100

Describe the change that occurs between points B →  C.

The kinetic energy is constant & potential energy increases

200

Now that you have avoided being grounded you get greedy and decide to add more sugar to the drink.  How can you dissolve more sugar?

Increase the temperature.

300

List three physical properties

Color, density, state of matter, solubility, melting point.

Unit 5

100

100 gram block of copper at 20 ∘C lowered into 100 grams of water at 100 ∘C. Heat will flow from ____ to ______ until it reaches ________?

The water to the copper until thermal equilibrium.

200

100 g of water was heated from 30*C to 80*C. The specific heat of water is 4.18 J/g*C.

20,900 J

300

List two chemical properties.

reactivity, combustibility, corrosivity, toxicity
